We divide 86450571 by 489
We want to divide 86450571 by 489.

Moving on to step 1:
489 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 489

Step 2:
86 divided by 489 is 0 with a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Append the next digit (4) from the dividend to 86 and continue with: 864 / 489

Going ahead to step 3:
864 divided by 489 is 1 with a remainder of 375.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 489 from 864 to get 375.
Fetch the next digit (5) from the dividend, attach it to 375 and continue: 3755 / 489

On to step 4:
When dividing 3755 by 489, we get 7 with a remainder of 332.
Write down 7 as next digit of the result. 
Result so far: 17.0
If we take 3423 away from 3755, we end up with 332.
Grab the next digit (0) from the dividend, add it to 332, then carry on: 3320 / 489

Going ahead to step 5:
The number 489 fits into 3320 6 times, leaving a remainder of 386.
Put 6 as the next digit of the answer. 
Result so far: 176.0
Subtract 2934 from 3320 to get 386.
Take the next digit (5) from the dividend and append it to 386, then repeat: 3865 / 489

Step 6:
If we divide 3865 by 489, we get 7 and a remainder of 442.
Write down 7 as next digit of the result. 
Result so far: 1767.0
The remainder is 442 after subtracting 3423 from 3865.
Append the next digit (7) from the dividend to 442 and continue with: 4427 / 489

On to step 7:
489 goes into 4427 9 times with a remainder of 26.
Write down 9 as next digit of the result. 
Result so far: 17679.0
Deduct 4401 from 4427 and we're left with 26.
Append the next digit (1) from the dividend to 26 and continue with: 261 / 489

Let's proceed to step 8:
When dividing 261 by 489, we get 0 with a remainder of 261.
Use 0 as the next digit of our solution. 
Result so far: 176790.0
Subtracting 0 from 261 leaves us with 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Moving on to step 9:
If we divide 2610 by 489, we get 5 and a remainder of 165.
Use 5 as the next digit of our solution. 
Result so far: 176790.5
Subtract 2445 from 2610 to get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Advancing to step 10:
The number 489 fits into 1650 3 times, leaving a remainder of 183.
Put 3 as the next digit of the answer. 
Result so far: 176790.53
If we take 1467 away from 1650, we end up with 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Going ahead to step 11:
1830 divided by 489 is 3 with a remainder of 363.
Record the quotient 3 as the next digit in the result. 
Result so far: 176790.533
If we subtract 1467 from 1830, we get 363.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3630, and continue the process.

Our division results in 176790.533 with a remaining 0.0363.
