Let's divide 39908357 by 851
We want to divide 39908357 by 851.

Step 1:
851 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 851

Moving on to step 2:
851 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
Deduct 0 from 39 and we're left with 39.
Include the next digit (9) from the dividend after 39, then repeat: 399 / 851

Moving on to step 3:
If we divide 399 by 851, we get 0 and a remainder of 399.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 399, we end up with 399.
Include the next digit (0) from the dividend after 399, then repeat: 3990 / 851

Moving on to step 4:
If we divide 3990 by 851, we get 4 and a remainder of 586.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 3404 from 3990 leaves us with 586.
Fetch the next digit (8) from the dividend, attach it to 586 and continue: 5868 / 851

Going ahead to step 5:
851 can be fit into 5868 6 times, resulting in a remainder of 762.
The next digit of our result is 6. 
Result so far: 46.0
The remainder is 762 after subtracting 5106 from 5868.
Take the next digit (3) from the dividend and append it to 762, then repeat: 7623 / 851

Going ahead to step 6:
851 can be fit into 7623 8 times, resulting in a remainder of 815.
Write down 8 as next digit of the result. 
Result so far: 468.0
Subtract 6808 from 7623 to get 815.
Fetch the next digit (5) from the dividend, attach it to 815 and continue: 8155 / 851

Going ahead to step 7:
851 can be fit into 8155 9 times, resulting in a remainder of 496.
The number 9 becomes the next digit in our result. 
Result so far: 4689.0
Subtract 7659 from 8155 to get 496.
Take the next digit (7) from the dividend and append it to 496, then repeat: 4967 / 851

Let's proceed to step 8:
4967 divided by 851 is 5 with a remainder of 712.
Write down 5 as next digit of the result. 
Result so far: 46895.0
Subtract 4255 from 4967 to get 712.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7120, and continue the process.

Let's proceed to step 9:
7120 divided by 851 is 8 with a remainder of 312.
The number 8 becomes the next digit in our result. 
Result so far: 46895.8
Subtract 6808 from 7120 to get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

On to step 10:
851 can be fit into 3120 3 times, resulting in a remainder of 567.
Write down 3 as next digit of the result. 
Result so far: 46895.83
The remainder is 567 after subtracting 2553 from 3120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5670, and continue the process.

Moving on to step 11:
If we divide 5670 by 851, we get 6 and a remainder of 564.
The next digit of our result is 6. 
Result so far: 46895.836
The remainder is 564 after subtracting 5106 from 5670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

Moving on to step 12:
The number 851 fits into 5640 6 times, leaving a remainder of 534.
The next digit of our result is 6. 
Result so far: 46895.8366
Deduct 5106 from 5640 and we're left with 534.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

The final outcome is 46895.8366, with a leftover of 0.00534.
