93036159 divided by 870 
Our goal is to divide 93036159 by 870.

Going ahead to step 1:
If we divide 9 by 870, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 870

On to step 2:
The number 870 fits into 93 0 times, leaving a remainder of 93.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 93 to get 93.
Bring next digit (0) of the dividend behind the 93 and repeat the process: 930 / 870

Going ahead to step 3:
The number 870 fits into 930 1 times, leaving a remainder of 60.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 870 away from 930, we end up with 60.
Bring next digit (3) of the dividend behind the 60 and repeat the process: 603 / 870

Step 4:
If we divide 603 by 870, we get 0 and a remainder of 603.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Deduct 0 from 603 and we're left with 603.
Include the next digit (6) from the dividend after 603, then repeat: 6036 / 870

Let's proceed to step 5:
6036 divided by 870 is 6 with a remainder of 816.
Put 6 as the next digit of the answer. 
Result so far: 106.0
The remainder is 816 after subtracting 5220 from 6036.
Grab the next digit (1) from the dividend, add it to 816, then carry on: 8161 / 870

Advancing to step 6:
If we divide 8161 by 870, we get 9 and a remainder of 331.
The next digit of our result is 9. 
Result so far: 1069.0
Subtract 7830 from 8161 to get 331.
Bring next digit (5) of the dividend behind the 331 and repeat the process: 3315 / 870

Going ahead to step 7:
The number 870 fits into 3315 3 times, leaving a remainder of 705.
Put 3 as the next digit of the answer. 
Result so far: 10693.0
If we take 2610 away from 3315, we end up with 705.
Include the next digit (9) from the dividend after 705, then repeat: 7059 / 870

Step 8:
If we divide 7059 by 870, we get 8 and a remainder of 99.
Put 8 as the next digit of the answer. 
Result so far: 106938.0
Subtracting 6960 from 7059 leaves us with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

On to step 9:
870 can be fit into 990 1 times, resulting in a remainder of 120.
Record the quotient 1 as the next digit in the result. 
Result so far: 106938.1
Deduct 870 from 990 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 10:
1200 divided by 870 is 1 with a remainder of 330.
The number 1 becomes the next digit in our result. 
Result so far: 106938.11
If we subtract 870 from 1200, we get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

The final outcome is 106938.11, with a leftover of 0.33.
