We look at the division of 89016432 by 321 
We want to divide 89016432 by 321.

Advancing to step 1:
321 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 321

Moving on to step 2:
321 can be fit into 89 0 times, resulting in a remainder of 89.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 89 and we're left with 89.
Take the next digit (0) from the dividend and append it to 89, then repeat: 890 / 321

Moving on to step 3:
The number 321 fits into 890 2 times, leaving a remainder of 248.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 642 from 890 and we're left with 248.
Take the next digit (1) from the dividend and append it to 248, then repeat: 2481 / 321

Advancing to step 4:
When dividing 2481 by 321, we get 7 with a remainder of 234.
Use 7 as the next digit of our solution. 
Result so far: 27.0
Deduct 2247 from 2481 and we're left with 234.
Bring next digit (6) of the dividend behind the 234 and repeat the process: 2346 / 321

Moving on to step 5:
321 goes into 2346 7 times with a remainder of 99.
The number 7 becomes the next digit in our result. 
Result so far: 277.0
Subtracting 2247 from 2346 leaves us with 99.
Include the next digit (4) from the dividend after 99, then repeat: 994 / 321

Advancing to step 6:
If we divide 994 by 321, we get 3 and a remainder of 31.
Write down 3 as next digit of the result. 
Result so far: 2773.0
Deduct 963 from 994 and we're left with 31.
Take the next digit (3) from the dividend and append it to 31, then repeat: 313 / 321

Going ahead to step 7:
321 goes into 313 0 times with a remainder of 313.
The number 0 becomes the next digit in our result. 
Result so far: 27730.0
Deduct 0 from 313 and we're left with 313.
Fetch the next digit (2) from the dividend, attach it to 313 and continue: 3132 / 321

Moving on to step 8:
321 can be fit into 3132 9 times, resulting in a remainder of 243.
Record the quotient 9 as the next digit in the result. 
Result so far: 277309.0
If we subtract 2889 from 3132, we get 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

On to step 9:
2430 divided by 321 is 7 with a remainder of 183.
Write down 7 as next digit of the result. 
Result so far: 277309.7
The remainder is 183 after subtracting 2247 from 2430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Advancing to step 10:
If we divide 1830 by 321, we get 5 and a remainder of 225.
Record the quotient 5 as the next digit in the result. 
Result so far: 277309.75
The remainder is 225 after subtracting 1605 from 1830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Moving on to step 11:
The number 321 fits into 2250 7 times, leaving a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 277309.757
Subtract 2247 from 2250 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 12:
321 can be fit into 30 0 times, resulting in a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 277309.757
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 13:
If we divide 300 by 321, we get 0 and a remainder of 300.
Record the quotient 0 as the next digit in the result. 
Result so far: 277309.757
Subtracting 0 from 300 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The final outcome is 277309.757, with a leftover of 0.0003.
