Let's divide 139591 by 71
Our goal is to divide 139591 by 71.

On to step 1:
The number 71 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 71

Let's proceed to step 2:
When dividing 13 by 71, we get 0 with a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Grab the next digit (9) from the dividend, add it to 13, then carry on: 139 / 71

Advancing to step 3:
If we divide 139 by 71, we get 1 and a remainder of 68.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 71 from 139 to get 68.
Grab the next digit (5) from the dividend, add it to 68, then carry on: 685 / 71

Advancing to step 4:
The number 71 fits into 685 9 times, leaving a remainder of 46.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
If we subtract 639 from 685, we get 46.
Fetch the next digit (9) from the dividend, attach it to 46 and continue: 469 / 71

Advancing to step 5:
71 can be fit into 469 6 times, resulting in a remainder of 43.
The next digit of our result is 6. 
Result so far: 196.0
If we take 426 away from 469, we end up with 43.
Take the next digit (1) from the dividend and append it to 43, then repeat: 431 / 71

Let's proceed to step 6:
71 goes into 431 6 times with a remainder of 5.
Write down 6 as next digit of the result. 
Result so far: 1966.0
The remainder is 5 after subtracting 426 from 431.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 7:
71 goes into 50 0 times with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 1966.0
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 8:
71 can be fit into 500 7 times, resulting in a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 1966.07
Subtract 497 from 500 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 9:
The number 71 fits into 30 0 times, leaving a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 1966.07
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 10:
71 goes into 300 4 times with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 1966.0704
If we take 284 away from 300, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 11:
When dividing 160 by 71, we get 2 with a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 1966.07042
If we subtract 142 from 160, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 12:
71 goes into 180 2 times with a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 1966.070422
If we take 142 away from 180, we end up 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.

In conclusion, the division gives 1966.070422 with a balance of 3.8e-06.
