Let's divide 64389393 by 488
We want to figure out the number of times 64389393 can be divided by 488.

Moving on to step 1:
488 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 488

Moving on to step 2:
When dividing 64 by 488, we get 0 with a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Append the next digit (3) from the dividend to 64 and continue with: 643 / 488

Advancing to step 3:
488 goes into 643 1 times with a remainder of 155.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 488 from 643 leaves us with 155.
Take the next digit (8) from the dividend and append it to 155, then repeat: 1558 / 488

On to step 4:
488 can be fit into 1558 3 times, resulting in a remainder of 94.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we take 1464 away from 1558, we end up with 94.
Grab the next digit (9) from the dividend, add it to 94, then carry on: 949 / 488

On to step 5:
488 goes into 949 1 times with a remainder of 461.
Put 1 as the next digit of the answer. 
Result so far: 131.0
Subtracting 488 from 949 leaves us with 461.
Grab the next digit (3) from the dividend, add it to 461, then carry on: 4613 / 488

Moving on to step 6:
4613 divided by 488 is 9 with a remainder of 221.
The number 9 becomes the next digit in our result. 
Result so far: 1319.0
If we take 4392 away from 4613, we end up with 221.
Fetch the next digit (9) from the dividend, attach it to 221 and continue: 2219 / 488

Let's proceed to step 7:
When dividing 2219 by 488, we get 4 with a remainder of 267.
Put 4 as the next digit of the answer. 
Result so far: 13194.0
Subtracting 1952 from 2219 leaves us with 267.
Append the next digit (3) from the dividend to 267 and continue with: 2673 / 488

On to step 8:
488 goes into 2673 5 times with a remainder of 233.
Put 5 as the next digit of the answer. 
Result so far: 131945.0
Deduct 2440 from 2673 and we're left with 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Let's proceed to step 9:
488 goes into 2330 4 times with a remainder of 378.
Put 4 as the next digit of the answer. 
Result so far: 131945.4
Subtracting 1952 from 2330 leaves us with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Let's proceed to step 10:
The number 488 fits into 3780 7 times, leaving a remainder of 364.
Put 7 as the next digit of the answer. 
Result so far: 131945.47
If we take 3416 away from 3780, we end up with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Moving on to step 11:
488 can be fit into 3640 7 times, resulting in a remainder of 224.
The next digit of our result is 7. 
Result so far: 131945.477
The remainder is 224 after subtracting 3416 from 3640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Our division results in 131945.477 with a remaining 0.0224.
