57723244 ÷ 45 
Let's see how many times 45 fits into 57723244.

Going ahead to step 1:
When dividing 5 by 45, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 45

On to step 2:
57 divided by 45 is 1 with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 45 from 57 and we're left with 12.
Append the next digit (7) from the dividend to 12 and continue with: 127 / 45

Advancing to step 3:
The number 45 fits into 127 2 times, leaving a remainder of 37.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 90 away from 127, we end up with 37.
Bring next digit (2) of the dividend behind the 37 and repeat the process: 372 / 45

Step 4:
45 goes into 372 8 times with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 128.0
Deduct 360 from 372 and we're left with 12.
Append the next digit (3) from the dividend to 12 and continue with: 123 / 45

Let's proceed to step 5:
When dividing 123 by 45, we get 2 with a remainder of 33.
The number 2 becomes the next digit in our result. 
Result so far: 1282.0
The remainder is 33 after subtracting 90 from 123.
Grab the next digit (2) from the dividend, add it to 33, then carry on: 332 / 45

Advancing to step 6:
45 goes into 332 7 times with a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 12827.0
Subtracting 315 from 332 leaves us with 17.
Fetch the next digit (4) from the dividend, attach it to 17 and continue: 174 / 45

On to step 7:
The number 45 fits into 174 3 times, leaving a remainder of 39.
Put 3 as the next digit of the answer. 
Result so far: 128273.0
Deduct 135 from 174 and we're left with 39.
Grab the next digit (4) from the dividend, add it to 39, then carry on: 394 / 45

Moving on to step 8:
If we divide 394 by 45, we get 8 and a remainder of 34.
Write down 8 as next digit of the result. 
Result so far: 1282738.0
The remainder is 34 after subtracting 360 from 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 9:
45 can be fit into 340 7 times, resulting in a remainder of 25.
Put 7 as the next digit of the answer. 
Result so far: 1282738.7
If we take 315 away from 340, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 10:
The number 45 fits into 250 5 times, leaving a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 1282738.75
If we subtract 225 from 250, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 11:
If we divide 250 by 45, we get 5 and a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 1282738.755
If we take 225 away from 250, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Our division results in 1282738.755 with a remaining 0.0025.
