We're dividing 43147170 by 915 
We want to figure out the number of times 43147170 can be divided by 915.

Going ahead to step 1:
915 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 915

Moving on to step 2:
915 can be fit into 43 0 times, resulting in a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Bring next digit (1) of the dividend behind the 43 and repeat the process: 431 / 915

Step 3:
If we divide 431 by 915, we get 0 and a remainder of 431.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 431 to get 431.
Fetch the next digit (4) from the dividend, attach it to 431 and continue: 4314 / 915

Going ahead to step 4:
915 goes into 4314 4 times with a remainder of 654.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 654 after subtracting 3660 from 4314.
Append the next digit (7) from the dividend to 654 and continue with: 6547 / 915

Going ahead to step 5:
When dividing 6547 by 915, we get 7 with a remainder of 142.
The number 7 becomes the next digit in our result. 
Result so far: 47.0
The remainder is 142 after subtracting 6405 from 6547.
Take the next digit (1) from the dividend and append it to 142, then repeat: 1421 / 915

Going ahead to step 6:
If we divide 1421 by 915, we get 1 and a remainder of 506.
The number 1 becomes the next digit in our result. 
Result so far: 471.0
Deduct 915 from 1421 and we're left with 506.
Fetch the next digit (7) from the dividend, attach it to 506 and continue: 5067 / 915

Moving on to step 7:
The number 915 fits into 5067 5 times, leaving a remainder of 492.
Use 5 as the next digit of our solution. 
Result so far: 4715.0
If we take 4575 away from 5067, we end up with 492.
Take the next digit (0) from the dividend and append it to 492, then repeat: 4920 / 915

Advancing to step 8:
4920 divided by 915 is 5 with a remainder of 345.
Put 5 as the next digit of the answer. 
Result so far: 47155.0
If we subtract 4575 from 4920, we get 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

On to step 9:
When dividing 3450 by 915, we get 3 with a remainder of 705.
The number 3 becomes the next digit in our result. 
Result so far: 47155.3
Subtract 2745 from 3450 to get 705.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7050, and continue the process.

Step 10:
7050 divided by 915 is 7 with a remainder of 645.
Put 7 as the next digit of the answer. 
Result so far: 47155.37
If we subtract 6405 from 7050, we get 645.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6450, and continue the process.

Advancing to step 11:
When dividing 6450 by 915, we get 7 with a remainder of 45.
Use 7 as the next digit of our solution. 
Result so far: 47155.377
Deduct 6405 from 6450 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The final outcome is 47155.377, with a leftover of 0.0045.
