We divide 74649172 by 321
We want to figure out the number of times 74649172 can be divided by 321.

Step 1:
321 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 321

Going ahead to step 2:
When dividing 74 by 321, we get 0 with a remainder of 74.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 74 after subtracting 0 from 74.
Fetch the next digit (6) from the dividend, attach it to 74 and continue: 746 / 321

Step 3:
321 goes into 746 2 times with a remainder of 104.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 642 from 746 to get 104.
Include the next digit (4) from the dividend after 104, then repeat: 1044 / 321

Let's proceed to step 4:
The number 321 fits into 1044 3 times, leaving a remainder of 81.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
If we subtract 963 from 1044, we get 81.
Include the next digit (9) from the dividend after 81, then repeat: 819 / 321

On to step 5:
321 goes into 819 2 times with a remainder of 177.
Put 2 as the next digit of the answer. 
Result so far: 232.0
If we subtract 642 from 819, we get 177.
Fetch the next digit (1) from the dividend, attach it to 177 and continue: 1771 / 321

Moving on to step 6:
321 can be fit into 1771 5 times, resulting in a remainder of 166.
The next digit of our result is 5. 
Result so far: 2325.0
The remainder is 166 after subtracting 1605 from 1771.
Take the next digit (7) from the dividend and append it to 166, then repeat: 1667 / 321

On to step 7:
The number 321 fits into 1667 5 times, leaving a remainder of 62.
Record the quotient 5 as the next digit in the result. 
Result so far: 23255.0
Deduct 1605 from 1667 and we're left with 62.
Fetch the next digit (2) from the dividend, attach it to 62 and continue: 622 / 321

On to step 8:
If we divide 622 by 321, we get 1 and a remainder of 301.
The number 1 becomes the next digit in our result. 
Result so far: 232551.0
If we take 321 away from 622, we end up with 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Moving on to step 9:
321 can be fit into 3010 9 times, resulting in a remainder of 121.
The next digit of our result is 9. 
Result so far: 232551.9
If we take 2889 away from 3010, we end up with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

On to step 10:
1210 divided by 321 is 3 with a remainder of 247.
Write down 3 as next digit of the result. 
Result so far: 232551.93
Subtract 963 from 1210 to get 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Going ahead to step 11:
When dividing 2470 by 321, we get 7 with a remainder of 223.
Write down 7 as next digit of the result. 
Result so far: 232551.937
Subtracting 2247 from 2470 leaves us with 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

Let's proceed to step 12:
When dividing 2230 by 321, we get 6 with a remainder of 304.
Use 6 as the next digit of our solution. 
Result so far: 232551.9376
The remainder is 304 after subtracting 1926 from 2230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Advancing to step 13:
321 can be fit into 3040 9 times, resulting in a remainder of 151.
Write down 9 as next digit of the result. 
Result so far: 232551.93769
Subtracting 2889 from 3040 leaves us with 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

On to step 14:
The number 321 fits into 1510 4 times, leaving a remainder of 226.
The number 4 becomes the next digit in our result. 
Result so far: 232551.937694
Subtracting 1284 from 1510 leaves us with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

On to step 15:
The number 321 fits into 2260 7 times, leaving a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 232551.9376947
If we subtract 2247 from 2260, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 16:
321 goes into 130 0 times with a remainder of 130.
Put 0 as the next digit of the answer. 
Result so far: 232551.9376947
Deduct 0 from 130 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Our division results in 232551.9376947 with a remaining 1.3e-07.
