Let's divide 66590630 by 424
We want to figure out the number of times 66590630 can be divided by 424.

Advancing to step 1:
When dividing 6 by 424, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 424

Step 2:
The number 424 fits into 66 0 times, leaving a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Take the next digit (5) from the dividend and append it to 66, then repeat: 665 / 424

Going ahead to step 3:
424 can be fit into 665 1 times, resulting in a remainder of 241.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 424 from 665, we get 241.
Bring next digit (9) of the dividend behind the 241 and repeat the process: 2419 / 424

Step 4:
424 can be fit into 2419 5 times, resulting in a remainder of 299.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we take 2120 away from 2419, we end up with 299.
Bring next digit (0) of the dividend behind the 299 and repeat the process: 2990 / 424

Advancing to step 5:
2990 divided by 424 is 7 with a remainder of 22.
The number 7 becomes the next digit in our result. 
Result so far: 157.0
The remainder is 22 after subtracting 2968 from 2990.
Grab the next digit (6) from the dividend, add it to 22, then carry on: 226 / 424

Advancing to step 6:
When dividing 226 by 424, we get 0 with a remainder of 226.
Put 0 as the next digit of the answer. 
Result so far: 1570.0
The remainder is 226 after subtracting 0 from 226.
Append the next digit (3) from the dividend to 226 and continue with: 2263 / 424

Moving on to step 7:
The number 424 fits into 2263 5 times, leaving a remainder of 143.
Use 5 as the next digit of our solution. 
Result so far: 15705.0
Subtracting 2120 from 2263 leaves us with 143.
Include the next digit (0) from the dividend after 143, then repeat: 1430 / 424

Advancing to step 8:
The number 424 fits into 1430 3 times, leaving a remainder of 158.
Write down 3 as next digit of the result. 
Result so far: 157053.0
Subtract 1272 from 1430 to get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Advancing to step 9:
If we divide 1580 by 424, we get 3 and a remainder of 308.
The next digit of our result is 3. 
Result so far: 157053.3
If we subtract 1272 from 1580, we get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Step 10:
424 can be fit into 3080 7 times, resulting in a remainder of 112.
The next digit of our result is 7. 
Result so far: 157053.37
Subtract 2968 from 3080 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Step 11:
424 goes into 1120 2 times with a remainder of 272.
The next digit of our result is 2. 
Result so far: 157053.372
If we take 848 away from 1120, we end up with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Step 12:
2720 divided by 424 is 6 with a remainder of 176.
The next digit of our result is 6. 
Result so far: 157053.3726
If we subtract 2544 from 2720, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

On to step 13:
If we divide 1760 by 424, we get 4 and a remainder of 64.
Put 4 as the next digit of the answer. 
Result so far: 157053.37264
Subtract 1696 from 1760 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 14:
640 divided by 424 is 1 with a remainder of 216.
Write down 1 as next digit of the result. 
Result so far: 157053.372641
If we subtract 424 from 640, we get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Going ahead to step 15:
The number 424 fits into 2160 5 times, leaving a remainder of 40.
The next digit of our result is 5. 
Result so far: 157053.3726415
Subtracting 2120 from 2160 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 16:
When dividing 400 by 424, we get 0 with a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 157053.3726415
Subtracting 0 from 400 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

In conclusion, the division gives 157053.3726415 with a balance of 4e-07.
