We divide 31642494 by 129
We're looking to find how many times 129 goes into 31642494.

On to step 1:
The number 129 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 129

Going ahead to step 2:
31 divided by 129 is 0 with a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Bring next digit (6) of the dividend behind the 31 and repeat the process: 316 / 129

Moving on to step 3:
316 divided by 129 is 2 with a remainder of 58.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 258 away from 316, we end up with 58.
Include the next digit (4) from the dividend after 58, then repeat: 584 / 129

Moving on to step 4:
584 divided by 129 is 4 with a remainder of 68.
Use 4 as the next digit of our solution. 
Result so far: 24.0
Subtracting 516 from 584 leaves us with 68.
Append the next digit (2) from the dividend to 68 and continue with: 682 / 129

On to step 5:
The number 129 fits into 682 5 times, leaving a remainder of 37.
Write down 5 as next digit of the result. 
Result so far: 245.0
If we take 645 away from 682, we end up with 37.
Grab the next digit (4) from the dividend, add it to 37, then carry on: 374 / 129

On to step 6:
When dividing 374 by 129, we get 2 with a remainder of 116.
The next digit of our result is 2. 
Result so far: 2452.0
Deduct 258 from 374 and we're left with 116.
Fetch the next digit (9) from the dividend, attach it to 116 and continue: 1169 / 129

Let's proceed to step 7:
129 goes into 1169 9 times with a remainder of 8.
The next digit of our result is 9. 
Result so far: 24529.0
Subtract 1161 from 1169 to get 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 129

Let's proceed to step 8:
When dividing 84 by 129, we get 0 with a remainder of 84.
Put 0 as the next digit of the answer. 
Result so far: 245290.0
The remainder is 84 after subtracting 0 from 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 9:
840 divided by 129 is 6 with a remainder of 66.
The next digit of our result is 6. 
Result so far: 245290.6
Deduct 774 from 840 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 10:
The number 129 fits into 660 5 times, leaving a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 245290.65
Subtract 645 from 660 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 11:
150 divided by 129 is 1 with a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 245290.651
Subtract 129 from 150 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 12:
If we divide 210 by 129, we get 1 and a remainder of 81.
Use 1 as the next digit of our solution. 
Result so far: 245290.6511
Subtract 129 from 210 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

The final outcome is 245290.6511, with a leftover of 0.00081.
