We look at the division of 55819791 by 139 
Our goal is to divide 55819791 by 139.

Step 1:
If we divide 5 by 139, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 139

Going ahead to step 2:
139 can be fit into 55 0 times, resulting in a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 55, we get 55.
Include the next digit (8) from the dividend after 55, then repeat: 558 / 139

Going ahead to step 3:
558 divided by 139 is 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 556 away from 558, we end up with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 139

On to step 4:
139 goes into 21 0 times with a remainder of 21.
The next digit of our result is 0. 
Result so far: 40.0
Subtracting 0 from 21 leaves us with 21.
Bring next digit (9) of the dividend behind the 21 and repeat the process: 219 / 139

On to step 5:
The number 139 fits into 219 1 times, leaving a remainder of 80.
The next digit of our result is 1. 
Result so far: 401.0
Subtracting 139 from 219 leaves us with 80.
Fetch the next digit (7) from the dividend, attach it to 80 and continue: 807 / 139

Step 6:
When dividing 807 by 139, we get 5 with a remainder of 112.
The number 5 becomes the next digit in our result. 
Result so far: 4015.0
If we take 695 away from 807, we end up with 112.
Grab the next digit (9) from the dividend, add it to 112, then carry on: 1129 / 139

Moving on to step 7:
139 goes into 1129 8 times with a remainder of 17.
The next digit of our result is 8. 
Result so far: 40158.0
Subtracting 1112 from 1129 leaves us with 17.
Append the next digit (1) from the dividend to 17 and continue with: 171 / 139

Advancing to step 8:
If we divide 171 by 139, we get 1 and a remainder of 32.
Put 1 as the next digit of the answer. 
Result so far: 401581.0
If we subtract 139 from 171, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 9:
When dividing 320 by 139, we get 2 with a remainder of 42.
Use 2 as the next digit of our solution. 
Result so far: 401581.2
The remainder is 42 after subtracting 278 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 10:
If we divide 420 by 139, we get 3 and a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 401581.23
Subtracting 417 from 420 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 11:
30 divided by 139 is 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 401581.23
Subtract 0 from 30 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.

Advancing to step 12:
300 divided by 139 is 2 with a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 401581.2302
Subtracting 278 from 300 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 13:
139 goes into 220 1 times with a remainder of 81.
Write down 1 as next digit of the result. 
Result so far: 401581.23021
Deduct 139 from 220 and we're left with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Advancing to step 14:
The number 139 fits into 810 5 times, leaving a remainder of 115.
Put 5 as the next digit of the answer. 
Result so far: 401581.230215
If we subtract 695 from 810, we get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

On to step 15:
If we divide 1150 by 139, we get 8 and a remainder of 38.
Use 8 as the next digit of our solution. 
Result so far: 401581.2302158
Deduct 1112 from 1150 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 16:
If we divide 380 by 139, we get 2 and a remainder of 102.
Use 2 as the next digit of our solution. 
Result so far: 401581.23021582
Deduct 278 from 380 and we're left with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

The final result is 401581.23021582 with a remainder of 1.02e-07.
