We're dividing 17875444 by 129 
We want to divide 17875444 by 129.

Advancing to step 1:
The number 129 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 129

Advancing to step 2:
129 goes into 17 0 times with a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 17 leaves us with 17.
Grab the next digit (8) from the dividend, add it to 17, then carry on: 178 / 129

Let's proceed to step 3:
When dividing 178 by 129, we get 1 with a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 129 from 178, we get 49.
Append the next digit (7) from the dividend to 49 and continue with: 497 / 129

Moving on to step 4:
129 goes into 497 3 times with a remainder of 110.
The next digit of our result is 3. 
Result so far: 13.0
If we subtract 387 from 497, we get 110.
Take the next digit (5) from the dividend and append it to 110, then repeat: 1105 / 129

On to step 5:
The number 129 fits into 1105 8 times, leaving a remainder of 73.
Put 8 as the next digit of the answer. 
Result so far: 138.0
Deduct 1032 from 1105 and we're left with 73.
Fetch the next digit (4) from the dividend, attach it to 73 and continue: 734 / 129

Let's proceed to step 6:
129 goes into 734 5 times with a remainder of 89.
Record the quotient 5 as the next digit in the result. 
Result so far: 1385.0
If we take 645 away from 734, we end up with 89.
Append the next digit (4) from the dividend to 89 and continue with: 894 / 129

Step 7:
129 goes into 894 6 times with a remainder of 120.
Put 6 as the next digit of the answer. 
Result so far: 13856.0
If we subtract 774 from 894, we get 120.
Grab the next digit (4) from the dividend, add it to 120, then carry on: 1204 / 129

Step 8:
1204 divided by 129 is 9 with a remainder of 43.
The next digit of our result is 9. 
Result so far: 138569.0
If we subtract 1161 from 1204, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 9:
430 divided by 129 is 3 with a remainder of 43.
The next digit of our result is 3. 
Result so far: 138569.3
Deduct 387 from 430 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 10:
129 goes into 430 3 times with a remainder of 43.
Record the quotient 3 as the next digit in the result. 
Result so far: 138569.33
Subtracting 387 from 430 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Our division results in 138569.33 with a remaining 0.043.
