Let's divide 66173432 by 488
We want to figure out the number of times 66173432 can be divided by 488.

Advancing to step 1:
488 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 488

Step 2:
488 can be fit into 66 0 times, resulting in a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Bring next digit (1) of the dividend behind the 66 and repeat the process: 661 / 488

Advancing to step 3:
661 divided by 488 is 1 with a remainder of 173.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 488 from 661 to get 173.
Take the next digit (7) from the dividend and append it to 173, then repeat: 1737 / 488

On to step 4:
488 goes into 1737 3 times with a remainder of 273.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we subtract 1464 from 1737, we get 273.
Append the next digit (3) from the dividend to 273 and continue with: 2733 / 488

Advancing to step 5:
488 goes into 2733 5 times with a remainder of 293.
Put 5 as the next digit of the answer. 
Result so far: 135.0
Subtract 2440 from 2733 to get 293.
Grab the next digit (4) from the dividend, add it to 293, then carry on: 2934 / 488

Moving on to step 6:
The number 488 fits into 2934 6 times, leaving a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 1356.0
The remainder is 6 after subtracting 2928 from 2934.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 488

Step 7:
63 divided by 488 is 0 with a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 13560.0
The remainder is 63 after subtracting 0 from 63.
Bring next digit (2) of the dividend behind the 63 and repeat the process: 632 / 488

Step 8:
The number 488 fits into 632 1 times, leaving a remainder of 144.
Put 1 as the next digit of the answer. 
Result so far: 135601.0
Deduct 488 from 632 and we're left with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Advancing to step 9:
When dividing 1440 by 488, we get 2 with a remainder of 464.
The number 2 becomes the next digit in our result. 
Result so far: 135601.2
Deduct 976 from 1440 and we're left with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Advancing to step 10:
488 can be fit into 4640 9 times, resulting in a remainder of 248.
Write down 9 as next digit of the result. 
Result so far: 135601.29
Deduct 4392 from 4640 and we're left with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Moving on to step 11:
When dividing 2480 by 488, we get 5 with a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 135601.295
If we subtract 2440 from 2480, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 12:
400 divided by 488 is 0 with a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 135601.295
If we subtract 0 from 400, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 13:
The number 488 fits into 4000 8 times, leaving a remainder of 96.
The next digit of our result is 8. 
Result so far: 135601.29508
Subtract 3904 from 4000 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Moving on to step 14:
When dividing 960 by 488, we get 1 with a remainder of 472.
Record the quotient 1 as the next digit in the result. 
Result so far: 135601.295081
Subtract 488 from 960 to get 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Moving on to step 15:
When dividing 4720 by 488, we get 9 with a remainder of 328.
Use 9 as the next digit of our solution. 
Result so far: 135601.2950819
If we subtract 4392 from 4720, we get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Going ahead to step 16:
488 can be fit into 3280 6 times, resulting in a remainder of 352.
Record the quotient 6 as the next digit in the result. 
Result so far: 135601.29508196
Subtract 2928 from 3280 to get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

The final outcome is 135601.29508196, with a leftover of 3.52e-07.
