Let's divide 15018348 by 870
We want to figure out the number of times 15018348 can be divided by 870.

On to step 1:
870 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 870

Moving on to step 2:
The number 870 fits into 15 0 times, leaving a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Take the next digit (0) from the dividend and append it to 15, then repeat: 150 / 870

Advancing to step 3:
If we divide 150 by 870, we get 0 and a remainder of 150.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 150 after subtracting 0 from 150.
Bring next digit (1) of the dividend behind the 150 and repeat the process: 1501 / 870

Step 4:
If we divide 1501 by 870, we get 1 and a remainder of 631.
The next digit of our result is 1. 
Result so far: 1.0
If we take 870 away from 1501, we end up with 631.
Grab the next digit (8) from the dividend, add it to 631, then carry on: 6318 / 870

Let's proceed to step 5:
6318 divided by 870 is 7 with a remainder of 228.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Subtracting 6090 from 6318 leaves us with 228.
Include the next digit (3) from the dividend after 228, then repeat: 2283 / 870

Advancing to step 6:
870 can be fit into 2283 2 times, resulting in a remainder of 543.
Write down 2 as next digit of the result. 
Result so far: 172.0
Subtracting 1740 from 2283 leaves us with 543.
Include the next digit (4) from the dividend after 543, then repeat: 5434 / 870

Going ahead to step 7:
If we divide 5434 by 870, we get 6 and a remainder of 214.
Write down 6 as next digit of the result. 
Result so far: 1726.0
Deduct 5220 from 5434 and we're left with 214.
Grab the next digit (8) from the dividend, add it to 214, then carry on: 2148 / 870

Going ahead to step 8:
870 goes into 2148 2 times with a remainder of 408.
Record the quotient 2 as the next digit in the result. 
Result so far: 17262.0
If we subtract 1740 from 2148, we get 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Step 9:
When dividing 4080 by 870, we get 4 with a remainder of 600.
Put 4 as the next digit of the answer. 
Result so far: 17262.4
If we subtract 3480 from 4080, we get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Moving on to step 10:
The number 870 fits into 6000 6 times, leaving a remainder of 780.
Use 6 as the next digit of our solution. 
Result so far: 17262.46
Subtract 5220 from 6000 to get 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 11:
When dividing 7800 by 870, we get 8 with a remainder of 840.
Write down 8 as next digit of the result. 
Result so far: 17262.468
If we take 6960 away from 7800, we end up 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.

Let's proceed to step 12:
870 can be fit into 8400 9 times, resulting in a remainder of 570.
Record the quotient 9 as the next digit in the result. 
Result so far: 17262.4689
Subtract 7830 from 8400 to get 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Going ahead to step 13:
If we divide 5700 by 870, we get 6 and a remainder of 480.
Record the quotient 6 as the next digit in the result. 
Result so far: 17262.46896
Subtracting 5220 from 5700 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Step 14:
When dividing 4800 by 870, we get 5 with a remainder of 450.
Put 5 as the next digit of the answer. 
Result so far: 17262.468965
Subtract 4350 from 4800 to get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

On to step 15:
870 goes into 4500 5 times with a remainder of 150.
The next digit of our result is 5. 
Result so far: 17262.4689655
Deduct 4350 from 4500 and we're left with 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 final result is 17262.4689655 with a remainder of 1.5e-06.
