We look at the division of 74559597 by 321 
We want to figure out the number of times 74559597 can be divided by 321.

Let's proceed to step 1:
When dividing 7 by 321, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 321

Advancing to step 2:
The number 321 fits into 74 0 times, leaving a remainder of 74.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 74 to get 74.
Fetch the next digit (5) from the dividend, attach it to 74 and continue: 745 / 321

Going ahead to step 3:
When dividing 745 by 321, we get 2 with a remainder of 103.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 642 from 745 and we're left with 103.
Grab the next digit (5) from the dividend, add it to 103, then carry on: 1035 / 321

Step 4:
1035 divided by 321 is 3 with a remainder of 72.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
The remainder is 72 after subtracting 963 from 1035.
Bring next digit (9) of the dividend behind the 72 and repeat the process: 729 / 321

Let's proceed to step 5:
729 divided by 321 is 2 with a remainder of 87.
Put 2 as the next digit of the answer. 
Result so far: 232.0
If we take 642 away from 729, we end up with 87.
Bring next digit (5) of the dividend behind the 87 and repeat the process: 875 / 321

Advancing to step 6:
875 divided by 321 is 2 with a remainder of 233.
Write down 2 as next digit of the result. 
Result so far: 2322.0
The remainder is 233 after subtracting 642 from 875.
Fetch the next digit (9) from the dividend, attach it to 233 and continue: 2339 / 321

Let's proceed to step 7:
If we divide 2339 by 321, we get 7 and a remainder of 92.
The number 7 becomes the next digit in our result. 
Result so far: 23227.0
Subtract 2247 from 2339 to get 92.
Grab the next digit (7) from the dividend, add it to 92, then carry on: 927 / 321

Moving on to step 8:
When dividing 927 by 321, we get 2 with a remainder of 285.
Record the quotient 2 as the next digit in the result. 
Result so far: 232272.0
If we subtract 642 from 927, we get 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Let's proceed to step 9:
When dividing 2850 by 321, we get 8 with a remainder of 282.
The next digit of our result is 8. 
Result so far: 232272.8
Deduct 2568 from 2850 and we're left with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Going ahead to step 10:
2820 divided by 321 is 8 with a remainder of 252.
Write down 8 as next digit of the result. 
Result so far: 232272.88
If we take 2568 away from 2820, we end up with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

The quotient of the division is 232272.88, and the remainder is 0.252.
