Let's divide 39923748 by 681
We want to divide 39923748 by 681.

Advancing to step 1:
When dividing 3 by 681, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 681

On to step 2:
681 can be fit into 39 0 times, resulting in a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Include the next digit (9) from the dividend after 39, then repeat: 399 / 681

Let's proceed to step 3:
399 divided by 681 is 0 with a remainder of 399.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 399 to get 399.
Take the next digit (2) from the dividend and append it to 399, then repeat: 3992 / 681

Step 4:
681 goes into 3992 5 times with a remainder of 587.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 3405 from 3992, we get 587.
Bring next digit (3) of the dividend behind the 587 and repeat the process: 5873 / 681

Advancing to step 5:
If we divide 5873 by 681, we get 8 and a remainder of 425.
Put 8 as the next digit of the answer. 
Result so far: 58.0
If we take 5448 away from 5873, we end up with 425.
Append the next digit (7) from the dividend to 425 and continue with: 4257 / 681

On to step 6:
681 goes into 4257 6 times with a remainder of 171.
The number 6 becomes the next digit in our result. 
Result so far: 586.0
If we take 4086 away from 4257, we end up with 171.
Fetch the next digit (4) from the dividend, attach it to 171 and continue: 1714 / 681

Going ahead to step 7:
681 goes into 1714 2 times with a remainder of 352.
Put 2 as the next digit of the answer. 
Result so far: 5862.0
If we subtract 1362 from 1714, we get 352.
Include the next digit (8) from the dividend after 352, then repeat: 3528 / 681

On to step 8:
The number 681 fits into 3528 5 times, leaving a remainder of 123.
The number 5 becomes the next digit in our result. 
Result so far: 58625.0
Deduct 3405 from 3528 and we're left with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Step 9:
The number 681 fits into 1230 1 times, leaving a remainder of 549.
Put 1 as the next digit of the answer. 
Result so far: 58625.1
If we subtract 681 from 1230, we get 549.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5490, and continue the process.

Going ahead to step 10:
The number 681 fits into 5490 8 times, leaving a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 58625.18
Subtract 5448 from 5490 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 11:
If we divide 420 by 681, we get 0 and a remainder of 420.
Put 0 as the next digit of the answer. 
Result so far: 58625.18
If we take 0 away from 420, we end up with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Moving on to step 12:
681 can be fit into 4200 6 times, resulting in a remainder of 114.
Put 6 as the next digit of the answer. 
Result so far: 58625.1806
If we subtract 4086 from 4200, we get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Advancing to step 13:
When dividing 1140 by 681, we get 1 with a remainder of 459.
The next digit of our result is 1. 
Result so far: 58625.18061
If we subtract 681 from 1140, we get 459.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4590, and continue the process.

On to step 14:
The number 681 fits into 4590 6 times, leaving a remainder of 504.
Use 6 as the next digit of our solution. 
Result so far: 58625.180616
If we take 4086 away from 4590, we end up with 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Step 15:
If we divide 5040 by 681, we get 7 and a remainder of 273.
The next digit of our result is 7. 
Result so far: 58625.1806167
Subtract 4767 from 5040 to get 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

Let's proceed to step 16:
681 can be fit into 2730 4 times, resulting in a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 58625.18061674
The remainder is 6 after subtracting 2724 from 2730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Our division results in 58625.18061674 with a remaining 6e-09.
