We look at the division of 12651810 by 874 
We want to divide 12651810 by 874.

Moving on to step 1:
874 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 874

Moving on to step 2:
If we divide 12 by 874, we get 0 and a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Include the next digit (6) from the dividend after 12, then repeat: 126 / 874

Moving on to step 3:
When dividing 126 by 874, we get 0 with a remainder of 126.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 126, we end up with 126.
Append the next digit (5) from the dividend to 126 and continue with: 1265 / 874

Going ahead to step 4:
874 goes into 1265 1 times with a remainder of 391.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 391 after subtracting 874 from 1265.
Append the next digit (1) from the dividend to 391 and continue with: 3911 / 874

Moving on to step 5:
The number 874 fits into 3911 4 times, leaving a remainder of 415.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Deduct 3496 from 3911 and we're left with 415.
Grab the next digit (8) from the dividend, add it to 415, then carry on: 4158 / 874

Advancing to step 6:
874 can be fit into 4158 4 times, resulting in a remainder of 662.
The next digit of our result is 4. 
Result so far: 144.0
If we subtract 3496 from 4158, we get 662.
Take the next digit (1) from the dividend and append it to 662, then repeat: 6621 / 874

Let's proceed to step 7:
If we divide 6621 by 874, we get 7 and a remainder of 503.
Put 7 as the next digit of the answer. 
Result so far: 1447.0
If we take 6118 away from 6621, we end up with 503.
Take the next digit (0) from the dividend and append it to 503, then repeat: 5030 / 874

Moving on to step 8:
If we divide 5030 by 874, we get 5 and a remainder of 660.
Write down 5 as next digit of the result. 
Result so far: 14475.0
The remainder is 660 after subtracting 4370 from 5030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Step 9:
874 can be fit into 6600 7 times, resulting in a remainder of 482.
Record the quotient 7 as the next digit in the result. 
Result so far: 14475.7
Subtract 6118 from 6600 to get 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Moving on to step 10:
874 can be fit into 4820 5 times, resulting in a remainder of 450.
The number 5 becomes the next digit in our result. 
Result so far: 14475.75
Subtract 4370 from 4820 to get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Advancing to step 11:
The number 874 fits into 4500 5 times, leaving a remainder of 130.
Write down 5 as next digit of the result. 
Result so far: 14475.755
If we take 4370 away from 4500, we end up 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 final outcome is 14475.755, with a leftover of 0.013.
