We divide 129251 by 878
We're looking to find how many times 878 goes into 129251.

Moving on to step 1:
If we divide 1 by 878, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 878

Step 2:
If we divide 12 by 878, we get 0 and a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 878

Advancing to step 3:
If we divide 129 by 878, we get 0 and a remainder of 129.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 129 and we're left with 129.
Bring next digit (2) of the dividend behind the 129 and repeat the process: 1292 / 878

On to step 4:
1292 divided by 878 is 1 with a remainder of 414.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 414 after subtracting 878 from 1292.
Grab the next digit (5) from the dividend, add it to 414, then carry on: 4145 / 878

Moving on to step 5:
878 goes into 4145 4 times with a remainder of 633.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we subtract 3512 from 4145, we get 633.
Append the next digit (1) from the dividend to 633 and continue with: 6331 / 878

Moving on to step 6:
If we divide 6331 by 878, we get 7 and a remainder of 185.
Use 7 as the next digit of our solution. 
Result so far: 147.0
Subtract 6146 from 6331 to get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Step 7:
878 goes into 1850 2 times with a remainder of 94.
The next digit of our result is 2. 
Result so far: 147.2
If we take 1756 away from 1850, we end up with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Step 8:
The number 878 fits into 940 1 times, leaving a remainder of 62.
The number 1 becomes the next digit in our result. 
Result so far: 147.21
Deduct 878 from 940 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 9:
620 divided by 878 is 0 with a remainder of 620.
Use 0 as the next digit of our solution. 
Result so far: 147.21
If we take 0 away from 620, we end up with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Going ahead to step 10:
6200 divided by 878 is 7 with a remainder of 54.
The next digit of our result is 7. 
Result so far: 147.2107
If we subtract 6146 from 6200, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 11:
878 goes into 540 0 times with a remainder of 540.
Put 0 as the next digit of the answer. 
Result so far: 147.2107
If we subtract 0 from 540, we get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Going ahead to step 12:
If we divide 5400 by 878, we get 6 and a remainder of 132.
Use 6 as the next digit of our solution. 
Result so far: 147.210706
Subtracting 5268 from 5400 leaves us with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Moving on to step 13:
878 can be fit into 1320 1 times, resulting in a remainder of 442.
The number 1 becomes the next digit in our result. 
Result so far: 147.2107061
The remainder is 442 after subtracting 878 from 1320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Let's proceed to step 14:
When dividing 4420 by 878, we get 5 with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 147.21070615
Subtract 4390 from 4420 to 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.

The final result is 147.21070615 with a remainder of 3e-08.
