We're dividing 57974654 by 45 
We're looking to find how many times 45 goes into 57974654.

Going ahead to step 1:
45 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 45

On to step 2:
The number 45 fits into 57 1 times, leaving a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 45 from 57, we get 12.
Append the next digit (9) from the dividend to 12 and continue with: 129 / 45

Advancing to step 3:
129 divided by 45 is 2 with a remainder of 39.
Write down 2 as next digit of the result. 
Result so far: 12.0
Deduct 90 from 129 and we're left with 39.
Bring next digit (7) of the dividend behind the 39 and repeat the process: 397 / 45

Step 4:
If we divide 397 by 45, we get 8 and a remainder of 37.
The next digit of our result is 8. 
Result so far: 128.0
Deduct 360 from 397 and we're left with 37.
Append the next digit (4) from the dividend to 37 and continue with: 374 / 45

Going ahead to step 5:
45 can be fit into 374 8 times, resulting in a remainder of 14.
The next digit of our result is 8. 
Result so far: 1288.0
Deduct 360 from 374 and we're left with 14.
Append the next digit (6) from the dividend to 14 and continue with: 146 / 45

Let's proceed to step 6:
45 can be fit into 146 3 times, resulting in a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 12883.0
Subtract 135 from 146 to get 11.
Fetch the next digit (5) from the dividend, attach it to 11 and continue: 115 / 45

Going ahead to step 7:
115 divided by 45 is 2 with a remainder of 25.
Put 2 as the next digit of the answer. 
Result so far: 128832.0
The remainder is 25 after subtracting 90 from 115.
Append the next digit (4) from the dividend to 25 and continue with: 254 / 45

Step 8:
45 can be fit into 254 5 times, resulting in a remainder of 29.
Put 5 as the next digit of the answer. 
Result so far: 1288325.0
The remainder is 29 after subtracting 225 from 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 9:
The number 45 fits into 290 6 times, leaving a remainder of 20.
The next digit of our result is 6. 
Result so far: 1288325.6
Subtracting 270 from 290 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 10:
200 divided by 45 is 4 with a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 1288325.64
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 11:
200 divided by 45 is 4 with a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 1288325.644
If we subtract 180 from 200, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 1288325.644 with a remaining 0.002.
