We look at the division of 38215902 by 851 
Our goal is to divide 38215902 by 851.

Step 1:
The number 851 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 851

Going ahead to step 2:
When dividing 38 by 851, we get 0 with a remainder of 38.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 38 after subtracting 0 from 38.
Bring next digit (2) of the dividend behind the 38 and repeat the process: 382 / 851

Advancing to step 3:
If we divide 382 by 851, we get 0 and a remainder of 382.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 382 to get 382.
Take the next digit (1) from the dividend and append it to 382, then repeat: 3821 / 851

Going ahead to step 4:
The number 851 fits into 3821 4 times, leaving a remainder of 417.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 417 after subtracting 3404 from 3821.
Include the next digit (5) from the dividend after 417, then repeat: 4175 / 851

Moving on to step 5:
851 goes into 4175 4 times with a remainder of 771.
The number 4 becomes the next digit in our result. 
Result so far: 44.0
The remainder is 771 after subtracting 3404 from 4175.
Include the next digit (9) from the dividend after 771, then repeat: 7719 / 851

Going ahead to step 6:
851 goes into 7719 9 times with a remainder of 60.
Write down 9 as next digit of the result. 
Result so far: 449.0
The remainder is 60 after subtracting 7659 from 7719.
Take the next digit (0) from the dividend and append it to 60, then repeat: 600 / 851

Step 7:
The number 851 fits into 600 0 times, leaving a remainder of 600.
The number 0 becomes the next digit in our result. 
Result so far: 4490.0
The remainder is 600 after subtracting 0 from 600.
Take the next digit (2) from the dividend and append it to 600, then repeat: 6002 / 851

Advancing to step 8:
When dividing 6002 by 851, we get 7 with a remainder of 45.
The number 7 becomes the next digit in our result. 
Result so far: 44907.0
Deduct 5957 from 6002 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 9:
If we divide 450 by 851, we get 0 and a remainder of 450.
Write down 0 as next digit of the result. 
Result so far: 44907.0
The remainder is 450 after subtracting 0 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Going ahead to step 10:
When dividing 4500 by 851, we get 5 with a remainder of 245.
Put 5 as the next digit of the answer. 
Result so far: 44907.05
If we subtract 4255 from 4500, we get 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Going ahead to step 11:
851 goes into 2450 2 times with a remainder of 748.
The number 2 becomes the next digit in our result. 
Result so far: 44907.052
Subtract 1702 from 2450 to get 748.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7480, and continue the process.

Let's proceed to step 12:
If we divide 7480 by 851, we get 8 and a remainder of 672.
Write down 8 as next digit of the result. 
Result so far: 44907.0528
Subtract 6808 from 7480 to get 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

On to step 13:
851 can be fit into 6720 7 times, resulting in a remainder of 763.
The number 7 becomes the next digit in our result. 
Result so far: 44907.05287
If we take 5957 away from 6720, we end up with 763.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7630, and continue the process.

Let's proceed to step 14:
The number 851 fits into 7630 8 times, leaving a remainder of 822.
The number 8 becomes the next digit in our result. 
Result so far: 44907.052878
The remainder is 822 after subtracting 6808 from 7630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8220, and continue the process.

Step 15:
851 can be fit into 8220 9 times, resulting in a remainder of 561.
Write down 9 as next digit of the result. 
Result so far: 44907.0528789
Subtracting 7659 from 8220 leaves us with 561.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5610, and continue the process.

Moving on to step 16:
5610 divided by 851 is 6 with a remainder of 504.
The next digit of our result is 6. 
Result so far: 44907.05287896
Subtracting 5106 from 5610 leaves us 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.

The final outcome is 44907.05287896, with a leftover of 5.04e-07.
