We divide 391274 by 45
Our goal is to divide 391274 by 45.

Let's proceed to step 1:
When dividing 3 by 45, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 45

Moving on to step 2:
45 goes into 39 0 times with a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Grab the next digit (1) from the dividend, add it to 39, then carry on: 391 / 45

Let's proceed to step 3:
45 can be fit into 391 8 times, resulting in a remainder of 31.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 360 from 391, we get 31.
Take the next digit (2) from the dividend and append it to 31, then repeat: 312 / 45

Moving on to step 4:
45 can be fit into 312 6 times, resulting in a remainder of 42.
Use 6 as the next digit of our solution. 
Result so far: 86.0
Subtract 270 from 312 to get 42.
Grab the next digit (7) from the dividend, add it to 42, then carry on: 427 / 45

Going ahead to step 5:
45 goes into 427 9 times with a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 869.0
Subtracting 405 from 427 leaves us with 22.
Append the next digit (4) from the dividend to 22 and continue with: 224 / 45

Moving on to step 6:
224 divided by 45 is 4 with a remainder of 44.
Use 4 as the next digit of our solution. 
Result so far: 8694.0
Subtracting 180 from 224 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 7:
If we divide 440 by 45, we get 9 and a remainder of 35.
Record the quotient 9 as the next digit in the result. 
Result so far: 8694.9
If we take 405 away from 440, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 8:
350 divided by 45 is 7 with a remainder of 35.
Write down 7 as next digit of the result. 
Result so far: 8694.97
The remainder is 35 after subtracting 315 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 9:
45 can be fit into 350 7 times, resulting in a remainder of 35.
Record the quotient 7 as the next digit in the result. 
Result so far: 8694.977
Subtract 315 from 350 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The quotient of the division is 8694.977, and the remainder is 0.0035.
