We look at the division of 139420 by 23 
Our goal is to divide 139420 by 23.

Let's proceed to step 1:
The number 23 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 23

Moving on to step 2:
If we divide 13 by 23, we get 0 and a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Fetch the next digit (9) from the dividend, attach it to 13 and continue: 139 / 23

Going ahead to step 3:
If we divide 139 by 23, we get 6 and a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we subtract 138 from 139, we get 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 23

On to step 4:
23 can be fit into 14 0 times, resulting in a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 60.0
Subtracting 0 from 14 leaves us with 14.
Take the next digit (2) from the dividend and append it to 14, then repeat: 142 / 23

Going ahead to step 5:
When dividing 142 by 23, we get 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 606.0
Subtracting 138 from 142 leaves us with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 23

On to step 6:
23 goes into 40 1 times with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 6061.0
The remainder is 17 after subtracting 23 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 7:
If we divide 170 by 23, we get 7 and a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 6061.7
Subtract 161 from 170 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 8:
90 divided by 23 is 3 with a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 6061.73
Subtracting 69 from 90 leaves us 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.

Moving on to step 9:
If we divide 210 by 23, we get 9 and a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 6061.739
Subtract 207 from 210 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.

Advancing to step 10:
The number 23 fits into 30 1 times, leaving a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 6061.7391
If we take 23 away from 30, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 11:
If we divide 70 by 23, we get 3 and a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 6061.73913
If we take 69 away from 70, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 12:
If we divide 10 by 23, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 6061.73913
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 13:
23 goes into 100 4 times with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 6061.7391304
If we take 92 away from 100, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 14:
If we divide 80 by 23, we get 3 and a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 6061.73913043
Subtracting 69 from 80 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

In conclusion, the division gives 6061.73913043 with a balance of 1.1e-08.
