We divide 54485923 by 43
We want to figure out the number of times 54485923 can be divided by 43.

On to step 1:
If we divide 5 by 43, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 43

Moving on to step 2:
When dividing 54 by 43, we get 1 with a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 43 from 54 and we're left with 11.
Grab the next digit (4) from the dividend, add it to 11, then carry on: 114 / 43

Let's proceed to step 3:
If we divide 114 by 43, we get 2 and a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 86 from 114 and we're left with 28.
Grab the next digit (8) from the dividend, add it to 28, then carry on: 288 / 43

Going ahead to step 4:
The number 43 fits into 288 6 times, leaving a remainder of 30.
Record the quotient 6 as the next digit in the result. 
Result so far: 126.0
If we subtract 258 from 288, we get 30.
Fetch the next digit (5) from the dividend, attach it to 30 and continue: 305 / 43

Going ahead to step 5:
43 goes into 305 7 times with a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 1267.0
If we take 301 away from 305, we end up with 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 43

Let's proceed to step 6:
49 divided by 43 is 1 with a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 12671.0
Subtract 43 from 49 to get 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 43

Advancing to step 7:
When dividing 62 by 43, we get 1 with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 126711.0
Subtracting 43 from 62 leaves us with 19.
Bring next digit (3) of the dividend behind the 19 and repeat the process: 193 / 43

Step 8:
If we divide 193 by 43, we get 4 and a remainder of 21.
Record the quotient 4 as the next digit in the result. 
Result so far: 1267114.0
Subtracting 172 from 193 leaves us 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:
43 can be fit into 210 4 times, resulting in a remainder of 38.
Record the quotient 4 as the next digit in the result. 
Result so far: 1267114.4
Subtracting 172 from 210 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.

Moving on to step 10:
380 divided by 43 is 8 with a remainder of 36.
The next digit of our result is 8. 
Result so far: 1267114.48
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.
Write down 8 as next digit of the result. 
Result so far: 1267114.488
If we subtract 344 from 360, we get 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 1267114.488, with a leftover of 0.0016.
