We look at the division of 86139 by 98 
We're looking to find how many times 98 goes into 86139.

Going ahead to step 1:
The number 98 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 98

Let's proceed to step 2:
86 divided by 98 is 0 with a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Grab the next digit (1) from the dividend, add it to 86, then carry on: 861 / 98

Going ahead to step 3:
The number 98 fits into 861 8 times, leaving a remainder of 77.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 784 from 861 to get 77.
Take the next digit (3) from the dividend and append it to 77, then repeat: 773 / 98

Moving on to step 4:
If we divide 773 by 98, we get 7 and a remainder of 87.
Write down 7 as next digit of the result. 
Result so far: 87.0
Subtracting 686 from 773 leaves us with 87.
Include the next digit (9) from the dividend after 87, then repeat: 879 / 98

Moving on to step 5:
When dividing 879 by 98, we get 8 with a remainder of 95.
Write down 8 as next digit of the result. 
Result so far: 878.0
If we take 784 away from 879, we end up with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Going ahead to step 6:
When dividing 950 by 98, we get 9 with a remainder of 68.
The next digit of our result is 9. 
Result so far: 878.9
Subtracting 882 from 950 leaves us 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.

Let's proceed to step 7:
98 goes into 680 6 times with a remainder of 92.
Record the quotient 6 as the next digit in the result. 
Result so far: 878.96
If we take 588 away from 680, we end up with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Advancing to step 8:
When dividing 920 by 98, we get 9 with a remainder of 38.
Record the quotient 9 as the next digit in the result. 
Result so far: 878.969
If we subtract 882 from 920, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 9:
98 can be fit into 380 3 times, resulting in a remainder of 86.
Record the quotient 3 as the next digit in the result. 
Result so far: 878.9693
If we take 294 away from 380, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Let's proceed to step 10:
If we divide 860 by 98, we get 8 and a remainder of 76.
The next digit of our result is 8. 
Result so far: 878.96938
Subtracting 784 from 860 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 11:
98 can be fit into 760 7 times, resulting in a remainder of 74.
Use 7 as the next digit of our solution. 
Result so far: 878.969387
If we take 686 away from 760, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 12:
The number 98 fits into 740 7 times, leaving a remainder of 54.
Use 7 as the next digit of our solution. 
Result so far: 878.9693877
If we subtract 686 from 740, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The quotient of the division is 878.9693877, and the remainder is 5.4e-07.
