43517070 ÷ 48 
We want to figure out the number of times 43517070 can be divided by 48.

Step 1:
48 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 48

Going ahead to step 2:
If we divide 43 by 48, we get 0 and a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Include the next digit (5) from the dividend after 43, then repeat: 435 / 48

Let's proceed to step 3:
48 can be fit into 435 9 times, resulting in a remainder of 3.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 432 from 435, we get 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 48

Let's proceed to step 4:
When dividing 31 by 48, we get 0 with a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 90.0
The remainder is 31 after subtracting 0 from 31.
Fetch the next digit (7) from the dividend, attach it to 31 and continue: 317 / 48

On to step 5:
The number 48 fits into 317 6 times, leaving a remainder of 29.
Record the quotient 6 as the next digit in the result. 
Result so far: 906.0
Deduct 288 from 317 and we're left with 29.
Bring next digit (0) of the dividend behind the 29 and repeat the process: 290 / 48

Going ahead to step 6:
The number 48 fits into 290 6 times, leaving a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 9066.0
Deduct 288 from 290 and we're left with 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 48

Step 7:
The number 48 fits into 27 0 times, leaving a remainder of 27.
Record the quotient 0 as the next digit in the result. 
Result so far: 90660.0
Subtract 0 from 27 to get 27.
Append the next digit (0) from the dividend to 27 and continue with: 270 / 48

Step 8:
270 divided by 48 is 5 with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 906605.0
If we subtract 240 from 270, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 9:
The number 48 fits into 300 6 times, leaving a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 906605.6
If we take 288 away from 300, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 10:
When dividing 120 by 48, we get 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 906605.62
Deduct 96 from 120 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 11:
When dividing 240 by 48, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 906605.625
The remainder is 0 after subtracting 240 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 12:
The number 48 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 906605.625
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 13:
48 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 906605.625
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 906605.625, with a leftover of 0.0.
