We divide 10478886 by 139
We want to divide 10478886 by 139.

On to step 1:
The number 139 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 139

Going ahead to step 2:
When dividing 10 by 139, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 10 after subtracting 0 from 10.
Fetch the next digit (4) from the dividend, attach it to 10 and continue: 104 / 139

Let's proceed to step 3:
If we divide 104 by 139, we get 0 and a remainder of 104.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 104 leaves us with 104.
Take the next digit (7) from the dividend and append it to 104, then repeat: 1047 / 139

On to step 4:
139 goes into 1047 7 times with a remainder of 74.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 973 from 1047, we get 74.
Bring next digit (8) of the dividend behind the 74 and repeat the process: 748 / 139

Step 5:
139 goes into 748 5 times with a remainder of 53.
Use 5 as the next digit of our solution. 
Result so far: 75.0
Deduct 695 from 748 and we're left with 53.
Fetch the next digit (8) from the dividend, attach it to 53 and continue: 538 / 139

Step 6:
The number 139 fits into 538 3 times, leaving a remainder of 121.
The next digit of our result is 3. 
Result so far: 753.0
Subtract 417 from 538 to get 121.
Take the next digit (8) from the dividend and append it to 121, then repeat: 1218 / 139

Going ahead to step 7:
When dividing 1218 by 139, we get 8 with a remainder of 106.
Use 8 as the next digit of our solution. 
Result so far: 7538.0
Deduct 1112 from 1218 and we're left with 106.
Grab the next digit (6) from the dividend, add it to 106, then carry on: 1066 / 139

Going ahead to step 8:
When dividing 1066 by 139, we get 7 with a remainder of 93.
The number 7 becomes the next digit in our result. 
Result so far: 75387.0
Subtracting 973 from 1066 leaves us with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Step 9:
930 divided by 139 is 6 with a remainder of 96.
Use 6 as the next digit of our solution. 
Result so far: 75387.6
Subtract 834 from 930 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 10:
139 can be fit into 960 6 times, resulting in a remainder of 126.
The number 6 becomes the next digit in our result. 
Result so far: 75387.66
The remainder is 126 after subtracting 834 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

The final result is 75387.66 with a remainder of 0.126.
