We divide 139897 by 23
Let's see how many times 23 fits into 139897.

Going ahead to step 1:
When dividing 1 by 23, we get 0 with a remainder of 1.
The next digit of our result is 0. 
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 / 23

Going ahead to step 2:
If we divide 13 by 23, we get 0 and a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Bring next digit (9) of the dividend behind the 13 and repeat the process: 139 / 23

Moving on to step 3:
23 goes into 139 6 times with a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 138 away from 139, we end up with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 23

Step 4:
23 goes into 18 0 times with a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 60.0
Subtracting 0 from 18 leaves us with 18.
Grab the next digit (9) from the dividend, add it to 18, then carry on: 189 / 23

Going ahead to step 5:
When dividing 189 by 23, we get 8 with a remainder of 5.
Record the quotient 8 as the next digit in the result. 
Result so far: 608.0
Subtract 184 from 189 to get 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 23

Going ahead to step 6:
When dividing 57 by 23, we get 2 with a remainder of 11.
The number 2 becomes the next digit in our result. 
Result so far: 6082.0
Subtract 46 from 57 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 7:
The number 23 fits into 110 4 times, leaving a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 6082.4
Subtract 92 from 110 to 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.

Step 8:
The number 23 fits into 180 7 times, leaving a remainder of 19.
The next digit of our result is 7. 
Result so far: 6082.47
Subtracting 161 from 180 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 9:
When dividing 190 by 23, we get 8 with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 6082.478
If we take 184 away from 190, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 10:
23 goes into 60 2 times with a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 6082.4782
If we take 46 away from 60, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 11:
140 divided by 23 is 6 with a remainder of 2.
The next digit of our result is 6. 
Result so far: 6082.47826
Deduct 138 from 140 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 12:
If we divide 20 by 23, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 6082.47826
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 13:
23 can be fit into 200 8 times, resulting in a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 6082.4782608
If we take 184 away from 200, 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.

Moving on to step 14:
160 divided by 23 is 6 with a remainder of 22.
The next digit of our result is 6. 
Result so far: 6082.47826086
If we subtract 138 from 160, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

After the division, we end up with 6082.47826086 and a remainder of 2.2e-08.
