Let's divide 138231 by 71
Our goal is to divide 138231 by 71.

Step 1:
If we divide 1 by 71, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 71

On to step 2:
71 can be fit into 13 0 times, resulting in a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 71

Going ahead to step 3:
If we divide 138 by 71, we get 1 and a remainder of 67.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 71 from 138 leaves us with 67.
Grab the next digit (2) from the dividend, add it to 67, then carry on: 672 / 71

Step 4:
71 goes into 672 9 times with a remainder of 33.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Subtracting 639 from 672 leaves us with 33.
Bring next digit (3) of the dividend behind the 33 and repeat the process: 333 / 71

Going ahead to step 5:
When dividing 333 by 71, we get 4 with a remainder of 49.
Record the quotient 4 as the next digit in the result. 
Result so far: 194.0
The remainder is 49 after subtracting 284 from 333.
Grab the next digit (1) from the dividend, add it to 49, then carry on: 491 / 71

Going ahead to step 6:
The number 71 fits into 491 6 times, leaving a remainder of 65.
The number 6 becomes the next digit in our result. 
Result so far: 1946.0
The remainder is 65 after subtracting 426 from 491.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 7:
When dividing 650 by 71, we get 9 with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 1946.9
The remainder is 11 after subtracting 639 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 8:
71 can be fit into 110 1 times, resulting in a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 1946.91
If we subtract 71 from 110, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 9:
390 divided by 71 is 5 with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 1946.915
Deduct 355 from 390 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 10:
350 divided by 71 is 4 with a remainder of 66.
The next digit of our result is 4. 
Result so far: 1946.9154
If we subtract 284 from 350, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 11:
If we divide 660 by 71, we get 9 and a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 1946.91549
Deduct 639 from 660 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 12:
210 divided by 71 is 2 with a remainder of 68.
The number 2 becomes the next digit in our result. 
Result so far: 1946.915492
The remainder is 68 after subtracting 142 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 13:
71 goes into 680 9 times with a remainder of 41.
Use 9 as the next digit of our solution. 
Result so far: 1946.9154929
If we subtract 639 from 680, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 14:
410 divided by 71 is 5 with a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 1946.91549295
Subtracting 355 from 410 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Our division results in 1946.91549295 with a remaining 5.5e-08.
