We look at the division of 13195969 by 878 
We want to divide 13195969 by 878.

Going ahead to step 1:
When dividing 1 by 878, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 878

Step 2:
878 goes into 13 0 times with a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Include the next digit (1) from the dividend after 13, then repeat: 131 / 878

Let's proceed to step 3:
131 divided by 878 is 0 with a remainder of 131.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 131 leaves us with 131.
Grab the next digit (9) from the dividend, add it to 131, then carry on: 1319 / 878

On to step 4:
If we divide 1319 by 878, we get 1 and a remainder of 441.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 878 away from 1319, we end up with 441.
Include the next digit (5) from the dividend after 441, then repeat: 4415 / 878

On to step 5:
If we divide 4415 by 878, we get 5 and a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtracting 4390 from 4415 leaves us with 25.
Take the next digit (9) from the dividend and append it to 25, then repeat: 259 / 878

Step 6:
878 goes into 259 0 times with a remainder of 259.
Put 0 as the next digit of the answer. 
Result so far: 150.0
Deduct 0 from 259 and we're left with 259.
Grab the next digit (6) from the dividend, add it to 259, then carry on: 2596 / 878

Moving on to step 7:
2596 divided by 878 is 2 with a remainder of 840.
Use 2 as the next digit of our solution. 
Result so far: 1502.0
The remainder is 840 after subtracting 1756 from 2596.
Append the next digit (9) from the dividend to 840 and continue with: 8409 / 878

Advancing to step 8:
If we divide 8409 by 878, we get 9 and a remainder of 507.
The next digit of our result is 9. 
Result so far: 15029.0
Deduct 7902 from 8409 and we're left with 507.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5070, and continue the process.

Moving on to step 9:
If we divide 5070 by 878, we get 5 and a remainder of 680.
The number 5 becomes the next digit in our result. 
Result so far: 15029.5
The remainder is 680 after subtracting 4390 from 5070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Going ahead to step 10:
878 goes into 6800 7 times with a remainder of 654.
Write down 7 as next digit of the result. 
Result so far: 15029.57
If we subtract 6146 from 6800, we get 654.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6540, and continue the process.

On to step 11:
If we divide 6540 by 878, we get 7 and a remainder of 394.
The number 7 becomes the next digit in our result. 
Result so far: 15029.577
If we take 6146 away from 6540, we end up with 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Our division results in 15029.577 with a remaining 0.0394.
