We're dividing 12657851 by 410 
Our goal is to divide 12657851 by 410.

On to step 1:
410 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 410

Going ahead to step 2:
410 can be fit into 12 0 times, resulting in a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Append the next digit (6) from the dividend to 12 and continue with: 126 / 410

Going ahead to step 3:
When dividing 126 by 410, we get 0 with a remainder of 126.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 126, we get 126.
Grab the next digit (5) from the dividend, add it to 126, then carry on: 1265 / 410

Going ahead to step 4:
410 can be fit into 1265 3 times, resulting in a remainder of 35.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 1230 from 1265 to get 35.
Include the next digit (7) from the dividend after 35, then repeat: 357 / 410

Step 5:
If we divide 357 by 410, we get 0 and a remainder of 357.
Write down 0 as next digit of the result. 
Result so far: 30.0
If we subtract 0 from 357, we get 357.
Include the next digit (8) from the dividend after 357, then repeat: 3578 / 410

Let's proceed to step 6:
410 can be fit into 3578 8 times, resulting in a remainder of 298.
Write down 8 as next digit of the result. 
Result so far: 308.0
If we take 3280 away from 3578, we end up with 298.
Bring next digit (5) of the dividend behind the 298 and repeat the process: 2985 / 410

Moving on to step 7:
2985 divided by 410 is 7 with a remainder of 115.
Record the quotient 7 as the next digit in the result. 
Result so far: 3087.0
The remainder is 115 after subtracting 2870 from 2985.
Grab the next digit (1) from the dividend, add it to 115, then carry on: 1151 / 410

On to step 8:
If we divide 1151 by 410, we get 2 and a remainder of 331.
The number 2 becomes the next digit in our result. 
Result so far: 30872.0
Subtracting 820 from 1151 leaves us with 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Advancing to step 9:
The number 410 fits into 3310 8 times, leaving a remainder of 30.
The next digit of our result is 8. 
Result so far: 30872.8
If we subtract 3280 from 3310, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 10:
410 goes into 300 0 times with a remainder of 300.
Record the quotient 0 as the next digit in the result. 
Result so far: 30872.8
Subtracting 0 from 300 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Let's proceed to step 11:
410 goes into 3000 7 times with a remainder of 130.
The next digit of our result is 7. 
Result so far: 30872.807
Subtract 2870 from 3000 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 12:
When dividing 1300 by 410, we get 3 with a remainder of 70.
Write down 3 as next digit of the result. 
Result so far: 30872.8073
Subtract 1230 from 1300 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 13:
410 can be fit into 700 1 times, resulting in a remainder of 290.
Write down 1 as next digit of the result. 
Result so far: 30872.80731
Subtract 410 from 700 to get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Advancing to step 14:
410 goes into 2900 7 times with a remainder of 30.
Put 7 as the next digit of the answer. 
Result so far: 30872.807317
If we take 2870 away from 2900, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 15:
410 can be fit into 300 0 times, resulting in a remainder of 300.
The next digit of our result is 0. 
Result so far: 30872.807317
Subtracting 0 from 300 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 16:
3000 divided by 410 is 7 with a remainder of 130.
Put 7 as the next digit of the answer. 
Result so far: 30872.80731707
Deduct 2870 from 3000 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

The quotient of the division is 30872.80731707, and the remainder is 1.3e-07.
