We look at the division of 13872393 by 139 
We're looking to find how many times 139 goes into 13872393.

Moving on to step 1:
The number 139 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 139

On to step 2:
139 goes into 13 0 times with 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 (8) from the dividend, attach it to 13 and continue: 138 / 139

On to step 3:
When dividing 138 by 139, we get 0 with a remainder of 138.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 138, we end up with 138.
Fetch the next digit (7) from the dividend, attach it to 138 and continue: 1387 / 139

On to step 4:
When dividing 1387 by 139, we get 9 with a remainder of 136.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtract 1251 from 1387 to get 136.
Take the next digit (2) from the dividend and append it to 136, then repeat: 1362 / 139

On to step 5:
The number 139 fits into 1362 9 times, leaving a remainder of 111.
Put 9 as the next digit of the answer. 
Result so far: 99.0
Subtracting 1251 from 1362 leaves us with 111.
Grab the next digit (3) from the dividend, add it to 111, then carry on: 1113 / 139

On to step 6:
If we divide 1113 by 139, we get 8 and a remainder of 1.
The next digit of our result is 8. 
Result so far: 998.0
If we take 1112 away from 1113, we end up with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 139

Going ahead to step 7:
139 goes into 19 0 times with a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 9980.0
Deduct 0 from 19 and we're left with 19.
Take the next digit (3) from the dividend and append it to 19, then repeat: 193 / 139

Moving on to step 8:
139 can be fit into 193 1 times, resulting in a remainder of 54.
The next digit of our result is 1. 
Result so far: 99801.0
The remainder is 54 after subtracting 139 from 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 9:
The number 139 fits into 540 3 times, leaving a remainder of 123.
Put 3 as the next digit of the answer. 
Result so far: 99801.3
If we subtract 417 from 540, we get 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Let's proceed to step 10:
1230 divided by 139 is 8 with a remainder of 118.
The number 8 becomes the next digit in our result. 
Result so far: 99801.38
Deduct 1112 from 1230 and we're left with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

On to step 11:
1180 divided by 139 is 8 with a remainder of 68.
Write down 8 as next digit of the result. 
Result so far: 99801.388
If we take 1112 away from 1180, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

In conclusion, the division gives 99801.388 with a balance of 0.0068.
