The number 993 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 993

Moving on to step 2:
42 divided by 993 is 0 with a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Bring next digit (4) of the dividend behind the 42 and repeat the process: 424 / 993

Advancing to step 3:
424 divided by 993 is 0 with a remainder of 424.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 424, we end up with 424.
Fetch the next digit (6) from the dividend, attach it to 424 and continue: 4246 / 993

Step 4:
The number 993 fits into 4246 4 times, leaving a remainder of 274.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 3972 from 4246 and we're left with 274.
Take the next digit (6) from the dividend and append it to 274, then repeat: 2746 / 993

On to step 5:
The number 993 fits into 2746 2 times, leaving a remainder of 760.
Put 2 as the next digit of the answer. 
Result so far: 42.0
Subtracting 1986 from 2746 leaves us with 760.
Grab the next digit (8) from the dividend, add it to 760, then carry on: 7608 / 993

Moving on to step 6:
993 goes into 7608 7 times with a remainder of 657.
Use 7 as the next digit of our solution. 
Result so far: 427.0
If we subtract 6951 from 7608, we get 657.
Bring next digit (3) of the dividend behind the 657 and repeat the process: 6573 / 993

Moving on to step 7:
When dividing 6573 by 993, we get 6 with a remainder of 615.
Put 6 as the next digit of the answer. 
Result so far: 4276.0
Subtract 5958 from 6573 to get 615.
Include the next digit (8) from the dividend after 615, then repeat: 6158 / 993

Advancing to step 8:
993 can be fit into 6158 6 times, resulting in a remainder of 200.
Use 6 as the next digit of our solution. 
Result so far: 42766.0
Deduct 5958 from 6158 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 9:
The number 993 fits into 2000 2 times, leaving a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 42766.2
Subtract 1986 from 2000 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 10:
If we divide 140 by 993, we get 0 and a remainder of 140.
Use 0 as the next digit of our solution. 
Result so far: 42766.2
If we take 0 away from 140, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 11:
When dividing 1400 by 993, we get 1 with a remainder of 407.
Use 1 as the next digit of our solution. 
Result so far: 42766.201
If we take 993 away from 1400, we end up with 407.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

Moving on to step 12:
When dividing 4070 by 993, we get 4 with a remainder of 98.
Put 4 as the next digit of the answer. 
Result so far: 42766.2014
Subtracting 3972 from 4070 leaves us with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Going ahead to step 13:
980 divided by 993 is 0 with a remainder of 980.
Record the quotient 0 as the next digit in the result. 
Result so far: 42766.2014
If we subtract 0 from 980, we get 980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9800, and continue the process.

Moving on to step 14:
993 goes into 9800 9 times with a remainder of 863.
Write down 9 as next digit of the result. 
Result so far: 42766.201409
Subtracting 8937 from 9800 leaves us with 863.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8630, and continue the process.

Advancing to step 15:
If we divide 8630 by 993, we get 8 and a remainder of 686.
The number 8 becomes the next digit in our result. 
Result so far: 42766.2014098
The remainder is 686 after subtracting 7944 from 8630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6860, and continue the process.

Step 16:
The number 993 fits into 6860 6 times, leaving a remainder of 902.
Record the quotient 6 as the next digit in the result. 
Result so far: 42766.20140986
Subtract 5958 from 6860 to get 902.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9020, and continue the process.

Our division results in 42766.20140986 with a remaining 9.02e-07.
