We look at the division of 25121477 by 851 
Our goal is to divide 25121477 by 851.

Moving on to step 1:
851 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 851

Moving on to step 2:
If we divide 25 by 851, we get 0 and a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Include the next digit (1) from the dividend after 25, then repeat: 251 / 851

Step 3:
If we divide 251 by 851, we get 0 and a remainder of 251.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 251 leaves us with 251.
Take the next digit (2) from the dividend and append it to 251, then repeat: 2512 / 851

On to step 4:
851 can be fit into 2512 2 times, resulting in a remainder of 810.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 810 after subtracting 1702 from 2512.
Fetch the next digit (1) from the dividend, attach it to 810 and continue: 8101 / 851

Advancing to step 5:
8101 divided by 851 is 9 with a remainder of 442.
Write down 9 as next digit of the result. 
Result so far: 29.0
The remainder is 442 after subtracting 7659 from 8101.
Include the next digit (4) from the dividend after 442, then repeat: 4424 / 851

Let's proceed to step 6:
4424 divided by 851 is 5 with a remainder of 169.
Put 5 as the next digit of the answer. 
Result so far: 295.0
The remainder is 169 after subtracting 4255 from 4424.
Fetch the next digit (7) from the dividend, attach it to 169 and continue: 1697 / 851

Moving on to step 7:
851 goes into 1697 1 times with a remainder of 846.
Use 1 as the next digit of our solution. 
Result so far: 2951.0
If we take 851 away from 1697, we end up with 846.
Append the next digit (7) from the dividend to 846 and continue with: 8467 / 851

On to step 8:
If we divide 8467 by 851, we get 9 and a remainder of 808.
Write down 9 as next digit of the result. 
Result so far: 29519.0
Subtract 7659 from 8467 to get 808.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8080, and continue the process.

Step 9:
The number 851 fits into 8080 9 times, leaving a remainder of 421.
Write down 9 as next digit of the result. 
Result so far: 29519.9
Subtract 7659 from 8080 to get 421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4210, and continue the process.

Going ahead to step 10:
When dividing 4210 by 851, we get 4 with a remainder of 806.
The next digit of our result is 4. 
Result so far: 29519.94
The remainder is 806 after subtracting 3404 from 4210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8060, and continue the process.

Let's proceed to step 11:
851 can be fit into 8060 9 times, resulting in a remainder of 401.
Put 9 as the next digit of the answer. 
Result so far: 29519.949
Subtract 7659 from 8060 to get 401.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4010, and continue the process.

Going ahead to step 12:
851 goes into 4010 4 times with a remainder of 606.
The number 4 becomes the next digit in our result. 
Result so far: 29519.9494
If we take 3404 away from 4010, we end up with 606.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6060, and continue the process.

On to step 13:
851 goes into 6060 7 times with a remainder of 103.
Use 7 as the next digit of our solution. 
Result so far: 29519.94947
Subtract 5957 from 6060 to get 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Let's proceed to step 14:
The number 851 fits into 1030 1 times, leaving a remainder of 179.
Record the quotient 1 as the next digit in the result. 
Result so far: 29519.949471
The remainder is 179 after subtracting 851 from 1030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Advancing to step 15:
If we divide 1790 by 851, we get 2 and a remainder of 88.
Write down 2 as next digit of the result. 
Result so far: 29519.9494712
The remainder is 88 after subtracting 1702 from 1790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 16:
When dividing 880 by 851, we get 1 with a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 29519.94947121
If we subtract 851 from 880, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

The quotient of the division is 29519.94947121, and the remainder is 2.9e-08.
