We're dividing 45239943 by 745 
We want to figure out the number of times 45239943 can be divided by 745.

Let's proceed to step 1:
745 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 745

Step 2:
The number 745 fits into 45 0 times, leaving a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Append the next digit (2) from the dividend to 45 and continue with: 452 / 745

Going ahead to step 3:
When dividing 452 by 745, we get 0 with a remainder of 452.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 452, we get 452.
Bring next digit (3) of the dividend behind the 452 and repeat the process: 4523 / 745

Let's proceed to step 4:
When dividing 4523 by 745, we get 6 with a remainder of 53.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we take 4470 away from 4523, we end up with 53.
Grab the next digit (9) from the dividend, add it to 53, then carry on: 539 / 745

Let's proceed to step 5:
539 divided by 745 is 0 with a remainder of 539.
Record the quotient 0 as the next digit in the result. 
Result so far: 60.0
The remainder is 539 after subtracting 0 from 539.
Include the next digit (9) from the dividend after 539, then repeat: 5399 / 745

Advancing to step 6:
When dividing 5399 by 745, we get 7 with a remainder of 184.
The next digit of our result is 7. 
Result so far: 607.0
If we subtract 5215 from 5399, we get 184.
Take the next digit (4) from the dividend and append it to 184, then repeat: 1844 / 745

Step 7:
745 can be fit into 1844 2 times, resulting in a remainder of 354.
Put 2 as the next digit of the answer. 
Result so far: 6072.0
Deduct 1490 from 1844 and we're left with 354.
Append the next digit (3) from the dividend to 354 and continue with: 3543 / 745

Moving on to step 8:
3543 divided by 745 is 4 with a remainder of 563.
Record the quotient 4 as the next digit in the result. 
Result so far: 60724.0
Subtracting 2980 from 3543 leaves us with 563.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5630, and continue the process.

Advancing to step 9:
If we divide 5630 by 745, we get 7 and a remainder of 415.
Put 7 as the next digit of the answer. 
Result so far: 60724.7
The remainder is 415 after subtracting 5215 from 5630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Advancing to step 10:
745 goes into 4150 5 times with a remainder of 425.
Use 5 as the next digit of our solution. 
Result so far: 60724.75
If we subtract 3725 from 4150, we get 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

On to step 11:
4250 divided by 745 is 5 with a remainder of 525.
Record the quotient 5 as the next digit in the result. 
Result so far: 60724.755
If we subtract 3725 from 4250, we get 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

In conclusion, the division gives 60724.755 with a balance of 0.0525.
