We look at the division of 98558985 by 870 
Our goal is to divide 98558985 by 870.

Moving on to step 1:
870 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 870

Going ahead to step 2:
When dividing 98 by 870, we get 0 with a remainder of 98.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 98 to get 98.
Grab the next digit (5) from the dividend, add it to 98, then carry on: 985 / 870

On to step 3:
870 goes into 985 1 times with a remainder of 115.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 870 from 985 to get 115.
Fetch the next digit (5) from the dividend, attach it to 115 and continue: 1155 / 870

On to step 4:
1155 divided by 870 is 1 with a remainder of 285.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtracting 870 from 1155 leaves us with 285.
Bring next digit (8) of the dividend behind the 285 and repeat the process: 2858 / 870

On to step 5:
870 goes into 2858 3 times with a remainder of 248.
Record the quotient 3 as the next digit in the result. 
Result so far: 113.0
Deduct 2610 from 2858 and we're left with 248.
Append the next digit (9) from the dividend to 248 and continue with: 2489 / 870

On to step 6:
When dividing 2489 by 870, we get 2 with a remainder of 749.
The number 2 becomes the next digit in our result. 
Result so far: 1132.0
If we subtract 1740 from 2489, we get 749.
Bring next digit (8) of the dividend behind the 749 and repeat the process: 7498 / 870

Step 7:
870 goes into 7498 8 times with a remainder of 538.
The next digit of our result is 8. 
Result so far: 11328.0
Subtract 6960 from 7498 to get 538.
Fetch the next digit (5) from the dividend, attach it to 538 and continue: 5385 / 870

Step 8:
870 goes into 5385 6 times with a remainder of 165.
Use 6 as the next digit of our solution. 
Result so far: 113286.0
Subtract 5220 from 5385 to get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

On to step 9:
870 can be fit into 1650 1 times, resulting in a remainder of 780.
The next digit of our result is 1. 
Result so far: 113286.1
If we take 870 away from 1650, we end up with 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

Advancing to step 10:
The number 870 fits into 7800 8 times, leaving a remainder of 840.
The number 8 becomes the next digit in our result. 
Result so far: 113286.18
Deduct 6960 from 7800 and we're left with 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8400, and continue the process.

Advancing to step 11:
8400 divided by 870 is 9 with a remainder of 570.
Put 9 as the next digit of the answer. 
Result so far: 113286.189
Subtracting 7830 from 8400 leaves us with 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Step 12:
The number 870 fits into 5700 6 times, leaving a remainder of 480.
The number 6 becomes the next digit in our result. 
Result so far: 113286.1896
If we subtract 5220 from 5700, we get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Going ahead to step 13:
If we divide 4800 by 870, we get 5 and a remainder of 450.
Use 5 as the next digit of our solution. 
Result so far: 113286.18965
The remainder is 450 after subtracting 4350 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Moving on to step 14:
When dividing 4500 by 870, we get 5 with a remainder of 150.
Use 5 as the next digit of our solution. 
Result so far: 113286.189655
If we subtract 4350 from 4500, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

The quotient of the division is 113286.189655, and the remainder is 1.5e-05.
