We're dividing 139818 by 23 
Let's see how many times 23 fits into 139818.

On to step 1:
If we divide 1 by 23, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 23

Advancing to step 2:
23 goes into 13 0 times with a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Fetch the next digit (9) from the dividend, attach it to 13 and continue: 139 / 23

Advancing to step 3:
139 divided by 23 is 6 with a remainder of 1.
The next digit of our result is 6. 
Result so far: 6.0
If we take 138 away from 139, we end up with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 23

Moving on to step 4:
If we divide 18 by 23, we get 0 and a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 60.0
Subtracting 0 from 18 leaves us with 18.
Include the next digit (1) from the dividend after 18, then repeat: 181 / 23

Advancing to step 5:
When dividing 181 by 23, we get 7 with a remainder of 20.
Use 7 as the next digit of our solution. 
Result so far: 607.0
The remainder is 20 after subtracting 161 from 181.
Fetch the next digit (8) from the dividend, attach it to 20 and continue: 208 / 23

Moving on to step 6:
If we divide 208 by 23, we get 9 and a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 6079.0
If we take 207 away from 208, 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.

Going ahead to step 7:
When dividing 10 by 23, we get 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 6079.0
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.

Moving on to step 8:
The number 23 fits into 100 4 times, leaving a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 6079.04
The remainder is 8 after subtracting 92 from 100.
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 9:
23 can be fit into 80 3 times, resulting in a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 6079.043
Deduct 69 from 80 and we're left 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.

Let's proceed to step 10:
110 divided by 23 is 4 with a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 6079.0434
If we subtract 92 from 110, 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.

Advancing to step 11:
If we divide 180 by 23, we get 7 and a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 6079.04347
Subtract 161 from 180 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 12:
When dividing 190 by 23, we get 8 with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 6079.043478
If we subtract 184 from 190, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 13:
If we divide 60 by 23, we get 2 and a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 6079.0434782
If we subtract 46 from 60, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 14:
23 can be fit into 140 6 times, resulting in a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 6079.04347826
If we subtract 138 from 140, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

In conclusion, the division gives 6079.04347826 with a balance of 2e-09.
