We look at the division of 78555596 by 139 
Our goal is to divide 78555596 by 139.

On to step 1:
7 divided by 139 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 139

Going ahead to step 2:
When dividing 78 by 139, we get 0 with a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Append the next digit (5) from the dividend to 78 and continue with: 785 / 139

Advancing to step 3:
If we divide 785 by 139, we get 5 and a remainder of 90.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 695 away from 785, we end up with 90.
Include the next digit (5) from the dividend after 90, then repeat: 905 / 139

Step 4:
If we divide 905 by 139, we get 6 and a remainder of 71.
Record the quotient 6 as the next digit in the result. 
Result so far: 56.0
If we take 834 away from 905, we end up with 71.
Append the next digit (5) from the dividend to 71 and continue with: 715 / 139

Let's proceed to step 5:
139 goes into 715 5 times with a remainder of 20.
The next digit of our result is 5. 
Result so far: 565.0
The remainder is 20 after subtracting 695 from 715.
Append the next digit (5) from the dividend to 20 and continue with: 205 / 139

Advancing to step 6:
If we divide 205 by 139, we get 1 and a remainder of 66.
The number 1 becomes the next digit in our result. 
Result so far: 5651.0
The remainder is 66 after subtracting 139 from 205.
Append the next digit (9) from the dividend to 66 and continue with: 669 / 139

Step 7:
If we divide 669 by 139, we get 4 and a remainder of 113.
Put 4 as the next digit of the answer. 
Result so far: 56514.0
Deduct 556 from 669 and we're left with 113.
Include the next digit (6) from the dividend after 113, then repeat: 1136 / 139

Moving on to step 8:
When dividing 1136 by 139, we get 8 with a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 565148.0
Deduct 1112 from 1136 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 9:
139 can be fit into 240 1 times, resulting in a remainder of 101.
The number 1 becomes the next digit in our result. 
Result so far: 565148.1
Subtract 139 from 240 to get 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Moving on to step 10:
139 goes into 1010 7 times with a remainder of 37.
Record the quotient 7 as the next digit in the result. 
Result so far: 565148.17
The remainder is 37 after subtracting 973 from 1010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 11:
The number 139 fits into 370 2 times, leaving a remainder of 92.
Record the quotient 2 as the next digit in the result. 
Result so far: 565148.172
Subtracting 278 from 370 leaves us with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Advancing to step 12:
If we divide 920 by 139, we get 6 and a remainder of 86.
Use 6 as the next digit of our solution. 
Result so far: 565148.1726
The remainder is 86 after subtracting 834 from 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

On to step 13:
139 goes into 860 6 times with a remainder of 26.
Record the quotient 6 as the next digit in the result. 
Result so far: 565148.17266
Subtracting 834 from 860 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final result is 565148.17266 with a remainder of 2.6e-05.
