Let's divide 64009980 by 993
Our goal is to divide 64009980 by 993.

Let's proceed to step 1:
When dividing 6 by 993, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 993

Moving on to step 2:
993 can be fit into 64 0 times, resulting in a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Bring next digit (0) of the dividend behind the 64 and repeat the process: 640 / 993

On to step 3:
993 can be fit into 640 0 times, resulting in a remainder of 640.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 640, we end up with 640.
Bring next digit (0) of the dividend behind the 640 and repeat the process: 6400 / 993

Going ahead to step 4:
993 goes into 6400 6 times with a remainder of 442.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 442 after subtracting 5958 from 6400.
Bring next digit (9) of the dividend behind the 442 and repeat the process: 4429 / 993

Advancing to step 5:
993 can be fit into 4429 4 times, resulting in a remainder of 457.
Put 4 as the next digit of the answer. 
Result so far: 64.0
Subtracting 3972 from 4429 leaves us with 457.
Grab the next digit (9) from the dividend, add it to 457, then carry on: 4579 / 993

Going ahead to step 6:
The number 993 fits into 4579 4 times, leaving a remainder of 607.
The number 4 becomes the next digit in our result. 
Result so far: 644.0
The remainder is 607 after subtracting 3972 from 4579.
Bring next digit (8) of the dividend behind the 607 and repeat the process: 6078 / 993

Step 7:
The number 993 fits into 6078 6 times, leaving a remainder of 120.
Write down 6 as next digit of the result. 
Result so far: 6446.0
Deduct 5958 from 6078 and we're left with 120.
Take the next digit (0) from the dividend and append it to 120, then repeat: 1200 / 993

Moving on to step 8:
If we divide 1200 by 993, we get 1 and a remainder of 207.
Write down 1 as next digit of the result. 
Result so far: 64461.0
Subtracting 993 from 1200 leaves us with 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Step 9:
993 goes into 2070 2 times with a remainder of 84.
Write down 2 as next digit of the result. 
Result so far: 64461.2
Deduct 1986 from 2070 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 10:
The number 993 fits into 840 0 times, leaving a remainder of 840.
Write down 0 as next digit of the result. 
Result so far: 64461.2
Subtract 0 from 840 to get 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8400, and continue the process.

Step 11:
8400 divided by 993 is 8 with a remainder of 456.
Use 8 as the next digit of our solution. 
Result so far: 64461.208
Deduct 7944 from 8400 and we're left with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

On to step 12:
993 goes into 4560 4 times with a remainder of 588.
Record the quotient 4 as the next digit in the result. 
Result so far: 64461.2084
The remainder is 588 after subtracting 3972 from 4560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

Advancing to step 13:
993 goes into 5880 5 times with a remainder of 915.
Use 5 as the next digit of our solution. 
Result so far: 64461.20845
Subtract 4965 from 5880 to get 915.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9150, and continue the process.

Going ahead to step 14:
993 goes into 9150 9 times with a remainder of 213.
Use 9 as the next digit of our solution. 
Result so far: 64461.208459
Deduct 8937 from 9150 and we're left with 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Moving on to step 15:
The number 993 fits into 2130 2 times, leaving a remainder of 144.
The next digit of our result is 2. 
Result so far: 64461.2084592
The remainder is 144 after subtracting 1986 from 2130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Step 16:
When dividing 1440 by 993, we get 1 with a remainder of 447.
The number 1 becomes the next digit in our result. 
Result so far: 64461.20845921
If we take 993 away from 1440, we end up with 447.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4470, and continue the process.

Our division results in 64461.20845921 with a remaining 4.47e-07.
