We divide 70030750 by 321
We want to figure out the number of times 70030750 can be divided by 321.

On to step 1:
7 divided by 321 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 321

Moving on to step 2:
If we divide 70 by 321, we get 0 and a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 70 to get 70.
Include the next digit (0) from the dividend after 70, then repeat: 700 / 321

Moving on to step 3:
The number 321 fits into 700 2 times, leaving a remainder of 58.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 642 from 700 to get 58.
Fetch the next digit (3) from the dividend, attach it to 58 and continue: 583 / 321

Moving on to step 4:
When dividing 583 by 321, we get 1 with a remainder of 262.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
Subtract 321 from 583 to get 262.
Fetch the next digit (0) from the dividend, attach it to 262 and continue: 2620 / 321

Step 5:
321 goes into 2620 8 times with a remainder of 52.
Record the quotient 8 as the next digit in the result. 
Result so far: 218.0
Deduct 2568 from 2620 and we're left with 52.
Bring next digit (7) of the dividend behind the 52 and repeat the process: 527 / 321

Step 6:
The number 321 fits into 527 1 times, leaving a remainder of 206.
Write down 1 as next digit of the result. 
Result so far: 2181.0
Subtracting 321 from 527 leaves us with 206.
Grab the next digit (5) from the dividend, add it to 206, then carry on: 2065 / 321

Going ahead to step 7:
The number 321 fits into 2065 6 times, leaving a remainder of 139.
Use 6 as the next digit of our solution. 
Result so far: 21816.0
If we subtract 1926 from 2065, we get 139.
Append the next digit (0) from the dividend to 139 and continue with: 1390 / 321

Let's proceed to step 8:
The number 321 fits into 1390 4 times, leaving a remainder of 106.
Record the quotient 4 as the next digit in the result. 
Result so far: 218164.0
Subtract 1284 from 1390 to get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Let's proceed to step 9:
1060 divided by 321 is 3 with a remainder of 97.
Use 3 as the next digit of our solution. 
Result so far: 218164.3
The remainder is 97 after subtracting 963 from 1060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Let's proceed to step 10:
321 goes into 970 3 times with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 218164.33
Deduct 963 from 970 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Our division results in 218164.33 with a remaining 0.007.
