75121064 ÷ 43 
We're looking to find how many times 43 goes into 75121064.

Going ahead to step 1:
43 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 43

Moving on to step 2:
When dividing 75 by 43, we get 1 with a remainder of 32.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 43 from 75, we get 32.
Include the next digit (1) from the dividend after 32, then repeat: 321 / 43

Advancing to step 3:
43 goes into 321 7 times with a remainder of 20.
Write down 7 as next digit of the result. 
Result so far: 17.0
Subtract 301 from 321 to get 20.
Append the next digit (2) from the dividend to 20 and continue with: 202 / 43

Advancing to step 4:
43 can be fit into 202 4 times, resulting in a remainder of 30.
Put 4 as the next digit of the answer. 
Result so far: 174.0
If we take 172 away from 202, we end up with 30.
Include the next digit (1) from the dividend after 30, then repeat: 301 / 43

Step 5:
If we divide 301 by 43, we get 7 and a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 1747.0
Deduct 301 from 301 and we're left with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 43

Going ahead to step 6:
43 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 17470.0
Deduct 0 from 0 and we're left with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 43

Advancing to step 7:
6 divided by 43 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 174700.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 43

Advancing to step 8:
43 can be fit into 64 1 times, resulting in a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 1747001.0
Deduct 43 from 64 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 9:
If we divide 210 by 43, we get 4 and a remainder of 38.
Put 4 as the next digit of the answer. 
Result so far: 1747001.4
If we take 172 away from 210, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 10:
43 can be fit into 380 8 times, resulting in a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 1747001.48
If we take 344 away from 380, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 11:
43 can be fit into 360 8 times, resulting in a remainder of 16.
The next digit of our result is 8. 
Result so far: 1747001.488
If we take 344 away from 360, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 1747001.488, with a leftover of 0.0016.
