20432348 divided by 43 
We want to figure out the number of times 20432348 can be divided by 43.

On to step 1:
When dividing 2 by 43, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 43

Moving on to step 2:
The number 43 fits into 20 0 times, leaving a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Take the next digit (4) from the dividend and append it to 20, then repeat: 204 / 43

On to step 3:
204 divided by 43 is 4 with a remainder of 32.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 172 from 204 leaves us with 32.
Include the next digit (3) from the dividend after 32, then repeat: 323 / 43

Advancing to step 4:
43 goes into 323 7 times with a remainder of 22.
Record the quotient 7 as the next digit in the result. 
Result so far: 47.0
Subtract 301 from 323 to get 22.
Bring next digit (2) of the dividend behind the 22 and repeat the process: 222 / 43

Advancing to step 5:
43 can be fit into 222 5 times, resulting in a remainder of 7.
The number 5 becomes the next digit in our result. 
Result so far: 475.0
Deduct 215 from 222 and we're left with 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 43

Moving on to step 6:
If we divide 73 by 43, we get 1 and a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 4751.0
Deduct 43 from 73 and we're left with 30.
Grab the next digit (4) from the dividend, add it to 30, then carry on: 304 / 43

Going ahead to step 7:
43 can be fit into 304 7 times, resulting in a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 47517.0
Deduct 301 from 304 and we're left with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 43

On to step 8:
The number 43 fits into 38 0 times, leaving a remainder of 38.
The number 0 becomes the next digit in our result. 
Result so far: 475170.0
Subtracting 0 from 38 leaves us 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.

Going ahead to step 9:
If we divide 380 by 43, we get 8 and a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 475170.8
If we subtract 344 from 380, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 10:
If we divide 360 by 43, we get 8 and a remainder of 16.
The next digit of our result is 8. 
Result so far: 475170.88
Deduct 344 from 360 and we're left 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 result is 475170.88 with a remainder of 0.016.
