Let's divide 66463931 by 681
We want to divide 66463931 by 681.

Advancing to step 1:
681 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 681

Step 2:
The number 681 fits into 66 0 times, leaving a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Append the next digit (4) from the dividend to 66 and continue with: 664 / 681

On to step 3:
When dividing 664 by 681, we get 0 with a remainder of 664.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 664 and we're left with 664.
Fetch the next digit (6) from the dividend, attach it to 664 and continue: 6646 / 681

Advancing to step 4:
6646 divided by 681 is 9 with a remainder of 517.
The next digit of our result is 9. 
Result so far: 9.0
If we take 6129 away from 6646, we end up with 517.
Take the next digit (3) from the dividend and append it to 517, then repeat: 5173 / 681

Advancing to step 5:
The number 681 fits into 5173 7 times, leaving a remainder of 406.
Write down 7 as next digit of the result. 
Result so far: 97.0
Deduct 4767 from 5173 and we're left with 406.
Grab the next digit (9) from the dividend, add it to 406, then carry on: 4069 / 681

On to step 6:
681 can be fit into 4069 5 times, resulting in a remainder of 664.
The number 5 becomes the next digit in our result. 
Result so far: 975.0
Subtracting 3405 from 4069 leaves us with 664.
Take the next digit (3) from the dividend and append it to 664, then repeat: 6643 / 681

Advancing to step 7:
If we divide 6643 by 681, we get 9 and a remainder of 514.
The next digit of our result is 9. 
Result so far: 9759.0
If we subtract 6129 from 6643, we get 514.
Include the next digit (1) from the dividend after 514, then repeat: 5141 / 681

Moving on to step 8:
If we divide 5141 by 681, we get 7 and a remainder of 374.
The number 7 becomes the next digit in our result. 
Result so far: 97597.0
Subtracting 4767 from 5141 leaves us with 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Moving on to step 9:
681 can be fit into 3740 5 times, resulting in a remainder of 335.
The next digit of our result is 5. 
Result so far: 97597.5
Deduct 3405 from 3740 and we're left with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Let's proceed to step 10:
3350 divided by 681 is 4 with a remainder of 626.
Record the quotient 4 as the next digit in the result. 
Result so far: 97597.54
Subtract 2724 from 3350 to get 626.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

Advancing to step 11:
6260 divided by 681 is 9 with a remainder of 131.
The number 9 becomes the next digit in our result. 
Result so far: 97597.549
Subtracting 6129 from 6260 leaves us with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Step 12:
If we divide 1310 by 681, we get 1 and a remainder of 629.
Write down 1 as next digit of the result. 
Result so far: 97597.5491
Subtracting 681 from 1310 leaves us with 629.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6290, and continue the process.

On to step 13:
681 can be fit into 6290 9 times, resulting in a remainder of 161.
Use 9 as the next digit of our solution. 
Result so far: 97597.54919
Subtract 6129 from 6290 to get 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Moving on to step 14:
If we divide 1610 by 681, we get 2 and a remainder of 248.
Put 2 as the next digit of the answer. 
Result so far: 97597.549192
Subtract 1362 from 1610 to get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Going ahead to step 15:
If we divide 2480 by 681, we get 3 and a remainder of 437.
Write down 3 as next digit of the result. 
Result so far: 97597.5491923
If we subtract 2043 from 2480, we get 437.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4370, and continue the process.

Going ahead to step 16:
681 can be fit into 4370 6 times, resulting in a remainder of 284.
Write down 6 as next digit of the result. 
Result so far: 97597.54919236
The remainder is 284 after subtracting 4086 from 4370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

The final result is 97597.54919236 with a remainder of 2.84e-07.
