42170494 divided by 993 
We're looking to find how many times 993 goes into 42170494.

Advancing to step 1:
993 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 993

Going ahead to step 2:
993 goes into 42 0 times with a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Append the next digit (1) from the dividend to 42 and continue with: 421 / 993

Advancing to step 3:
When dividing 421 by 993, we get 0 with a remainder of 421.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 421 leaves us with 421.
Bring next digit (7) of the dividend behind the 421 and repeat the process: 4217 / 993

Going ahead to step 4:
993 goes into 4217 4 times with a remainder of 245.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 3972 from 4217 to get 245.
Include the next digit (0) from the dividend after 245, then repeat: 2450 / 993

Advancing to step 5:
2450 divided by 993 is 2 with a remainder of 464.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
If we take 1986 away from 2450, we end up with 464.
Fetch the next digit (4) from the dividend, attach it to 464 and continue: 4644 / 993

Moving on to step 6:
993 goes into 4644 4 times with a remainder of 672.
Put 4 as the next digit of the answer. 
Result so far: 424.0
Subtracting 3972 from 4644 leaves us with 672.
Grab the next digit (9) from the dividend, add it to 672, then carry on: 6729 / 993

Going ahead to step 7:
If we divide 6729 by 993, we get 6 and a remainder of 771.
Record the quotient 6 as the next digit in the result. 
Result so far: 4246.0
The remainder is 771 after subtracting 5958 from 6729.
Take the next digit (4) from the dividend and append it to 771, then repeat: 7714 / 993

On to step 8:
If we divide 7714 by 993, we get 7 and a remainder of 763.
Write down 7 as next digit of the result. 
Result so far: 42467.0
The remainder is 763 after subtracting 6951 from 7714.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7630, and continue the process.

Let's proceed to step 9:
The number 993 fits into 7630 7 times, leaving a remainder of 679.
Record the quotient 7 as the next digit in the result. 
Result so far: 42467.7
If we take 6951 away from 7630, we end up with 679.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6790, and continue the process.

Let's proceed to step 10:
993 can be fit into 6790 6 times, resulting in a remainder of 832.
The number 6 becomes the next digit in our result. 
Result so far: 42467.76
If we subtract 5958 from 6790, we get 832.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8320, and continue the process.

Advancing to step 11:
If we divide 8320 by 993, we get 8 and a remainder of 376.
The next digit of our result is 8. 
Result so far: 42467.768
Deduct 7944 from 8320 and we're left with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Step 12:
993 goes into 3760 3 times with a remainder of 781.
Record the quotient 3 as the next digit in the result. 
Result so far: 42467.7683
The remainder is 781 after subtracting 2979 from 3760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7810, and continue the process.

On to step 13:
If we divide 7810 by 993, we get 7 and a remainder of 859.
Write down 7 as next digit of the result. 
Result so far: 42467.76837
If we take 6951 away from 7810, we end up with 859.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8590, and continue the process.

Going ahead to step 14:
993 can be fit into 8590 8 times, resulting in a remainder of 646.
The number 8 becomes the next digit in our result. 
Result so far: 42467.768378
Deduct 7944 from 8590 and we're left with 646.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6460, and continue the process.

Going ahead to step 15:
If we divide 6460 by 993, we get 6 and a remainder of 502.
Put 6 as the next digit of the answer. 
Result so far: 42467.7683786
If we take 5958 away from 6460, we end up with 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

Advancing to step 16:
When dividing 5020 by 993, we get 5 with a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 42467.76837865
If we subtract 4965 from 5020, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

After the division, we end up with 42467.76837865 and a remainder of 5.5e-08.
