We're dividing 870139 by 98 
Our goal is to divide 870139 by 98.

On 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
Subtracting 0 from 8 leaves us with 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 98

Going ahead to step 2:
87 divided by 98 is 0 with a remainder of 87.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 87 and we're left with 87.
Grab the next digit (0) from the dividend, add it to 87, then carry on: 870 / 98

Let's proceed to step 3:
870 divided by 98 is 8 with a remainder of 86.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 784 from 870 and we're left with 86.
Append the next digit (1) from the dividend to 86 and continue with: 861 / 98

Going ahead to step 4:
861 divided by 98 is 8 with a remainder of 77.
The next digit of our result is 8. 
Result so far: 88.0
Deduct 784 from 861 and we're left with 77.
Append the next digit (3) from the dividend to 77 and continue with: 773 / 98

On to step 5:
98 goes into 773 7 times with a remainder of 87.
Record the quotient 7 as the next digit in the result. 
Result so far: 887.0
Subtract 686 from 773 to get 87.
Include the next digit (9) from the dividend after 87, then repeat: 879 / 98

Going ahead to step 6:
When dividing 879 by 98, we get 8 with a remainder of 95.
Use 8 as the next digit of our solution. 
Result so far: 8878.0
Deduct 784 from 879 and we're left 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.

Advancing to step 7:
98 goes into 950 9 times with a remainder of 68.
Write down 9 as next digit of the result. 
Result so far: 8878.9
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.

Advancing to step 8:
When dividing 680 by 98, we get 6 with a remainder of 92.
Record the quotient 6 as the next digit in the result. 
Result so far: 8878.96
The remainder is 92 after subtracting 588 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Step 9:
If we divide 920 by 98, we get 9 and a remainder of 38.
Write down 9 as next digit of the result. 
Result so far: 8878.969
If we take 882 away from 920, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 10:
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: 8878.9693
Subtracting 294 from 380 leaves us 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.

Step 11:
The number 98 fits into 860 8 times, leaving a remainder of 76.
The number 8 becomes the next digit in our result. 
Result so far: 8878.96938
Deduct 784 from 860 and we're left 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.

Moving on to step 12:
98 can be fit into 760 7 times, resulting in a remainder of 74.
Put 7 as the next digit of the answer. 
Result so far: 8878.969387
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.

Moving on to step 13:
When dividing 740 by 98, we get 7 with a remainder of 54.
Record the quotient 7 as the next digit in the result. 
Result so far: 8878.9693877
Subtract 686 from 740 to 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.

Our division results in 8878.9693877 with a remaining 5.4e-07.
