45574231 ÷ 862 
We want to figure out the number of times 45574231 can be divided by 862.

Moving on to step 1:
862 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
Subtracting 0 from 4 leaves us with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 862

Step 2:
When dividing 45 by 862, we get 0 with 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.
Take the next digit (5) from the dividend and append it to 45, then repeat: 455 / 862

Advancing to step 3:
The number 862 fits into 455 0 times, leaving a remainder of 455.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 455 leaves us with 455.
Append the next digit (7) from the dividend to 455 and continue with: 4557 / 862

On to step 4:
When dividing 4557 by 862, we get 5 with a remainder of 247.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtracting 4310 from 4557 leaves us with 247.
Grab the next digit (4) from the dividend, add it to 247, then carry on: 2474 / 862

Moving on to step 5:
If we divide 2474 by 862, we get 2 and a remainder of 750.
The next digit of our result is 2. 
Result so far: 52.0
The remainder is 750 after subtracting 1724 from 2474.
Fetch the next digit (2) from the dividend, attach it to 750 and continue: 7502 / 862

Going ahead to step 6:
When dividing 7502 by 862, we get 8 with a remainder of 606.
Write down 8 as next digit of the result. 
Result so far: 528.0
The remainder is 606 after subtracting 6896 from 7502.
Append the next digit (3) from the dividend to 606 and continue with: 6063 / 862

On to step 7:
If we divide 6063 by 862, we get 7 and a remainder of 29.
The next digit of our result is 7. 
Result so far: 5287.0
Deduct 6034 from 6063 and we're left with 29.
Append the next digit (1) from the dividend to 29 and continue with: 291 / 862

Going ahead to step 8:
The number 862 fits into 291 0 times, leaving a remainder of 291.
Use 0 as the next digit of our solution. 
Result so far: 52870.0
If we subtract 0 from 291, we get 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Advancing to step 9:
When dividing 2910 by 862, we get 3 with a remainder of 324.
The number 3 becomes the next digit in our result. 
Result so far: 52870.3
Deduct 2586 from 2910 and we're left with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Going ahead to step 10:
If we divide 3240 by 862, we get 3 and a remainder of 654.
Put 3 as the next digit of the answer. 
Result so far: 52870.33
Subtract 2586 from 3240 to get 654.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6540, and continue the process.

The final outcome is 52870.33, with a leftover of 0.654.
