We're dividing 39715601 by 851 
Let's see how many times 851 fits into 39715601.

Advancing to step 1:
If we divide 3 by 851, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 851

Going ahead to step 2:
If we divide 39 by 851, we get 0 and a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Bring next digit (7) of the dividend behind the 39 and repeat the process: 397 / 851

Let's proceed to step 3:
397 divided by 851 is 0 with a remainder of 397.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 397 to get 397.
Include the next digit (1) from the dividend after 397, then repeat: 3971 / 851

Let's proceed to step 4:
If we divide 3971 by 851, we get 4 and a remainder of 567.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 3404 from 3971 to get 567.
Append the next digit (5) from the dividend to 567 and continue with: 5675 / 851

On to step 5:
851 can be fit into 5675 6 times, resulting in a remainder of 569.
Write down 6 as next digit of the result. 
Result so far: 46.0
Subtract 5106 from 5675 to get 569.
Fetch the next digit (6) from the dividend, attach it to 569 and continue: 5696 / 851

Step 6:
851 can be fit into 5696 6 times, resulting in a remainder of 590.
Put 6 as the next digit of the answer. 
Result so far: 466.0
Deduct 5106 from 5696 and we're left with 590.
Grab the next digit (0) from the dividend, add it to 590, then carry on: 5900 / 851

Step 7:
5900 divided by 851 is 6 with a remainder of 794.
Record the quotient 6 as the next digit in the result. 
Result so far: 4666.0
The remainder is 794 after subtracting 5106 from 5900.
Fetch the next digit (1) from the dividend, attach it to 794 and continue: 7941 / 851

Step 8:
7941 divided by 851 is 9 with a remainder of 282.
Write down 9 as next digit of the result. 
Result so far: 46669.0
Subtracting 7659 from 7941 leaves us with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Advancing to step 9:
The number 851 fits into 2820 3 times, leaving a remainder of 267.
Write down 3 as next digit of the result. 
Result so far: 46669.3
Subtracting 2553 from 2820 leaves us with 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Let's proceed to step 10:
851 goes into 2670 3 times with a remainder of 117.
The next digit of our result is 3. 
Result so far: 46669.33
The remainder is 117 after subtracting 2553 from 2670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

The quotient of the division is 46669.33, and the remainder is 0.117.
