We're dividing 66487990 by 113 
We want to figure out the number of times 66487990 can be divided by 113.

Advancing to step 1:
If we divide 6 by 113, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 113

Going ahead to step 2:
When dividing 66 by 113, we get 0 with a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Append the next digit (4) from the dividend to 66 and continue with: 664 / 113

Moving on to step 3:
113 can be fit into 664 5 times, resulting in a remainder of 99.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 565 from 664 and we're left with 99.
Fetch the next digit (8) from the dividend, attach it to 99 and continue: 998 / 113

Going ahead to step 4:
113 can be fit into 998 8 times, resulting in a remainder of 94.
The next digit of our result is 8. 
Result so far: 58.0
Subtracting 904 from 998 leaves us with 94.
Take the next digit (7) from the dividend and append it to 94, then repeat: 947 / 113

Moving on to step 5:
If we divide 947 by 113, we get 8 and a remainder of 43.
Put 8 as the next digit of the answer. 
Result so far: 588.0
Subtract 904 from 947 to get 43.
Fetch the next digit (9) from the dividend, attach it to 43 and continue: 439 / 113

Moving on to step 6:
The number 113 fits into 439 3 times, leaving a remainder of 100.
Put 3 as the next digit of the answer. 
Result so far: 5883.0
If we take 339 away from 439, we end up with 100.
Include the next digit (9) from the dividend after 100, then repeat: 1009 / 113

Going ahead to step 7:
113 can be fit into 1009 8 times, resulting in a remainder of 105.
The next digit of our result is 8. 
Result so far: 58838.0
Subtract 904 from 1009 to get 105.
Take the next digit (0) from the dividend and append it to 105, then repeat: 1050 / 113

Advancing to step 8:
113 can be fit into 1050 9 times, resulting in a remainder of 33.
The next digit of our result is 9. 
Result so far: 588389.0
If we take 1017 away from 1050, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 9:
If we divide 330 by 113, we get 2 and a remainder of 104.
Use 2 as the next digit of our solution. 
Result so far: 588389.2
Subtracting 226 from 330 leaves us with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Advancing to step 10:
The number 113 fits into 1040 9 times, leaving a remainder of 23.
The next digit of our result is 9. 
Result so far: 588389.29
If we subtract 1017 from 1040, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 11:
If we divide 230 by 113, we get 2 and a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 588389.292
Subtracting 226 from 230 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 12:
40 divided by 113 is 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 588389.292
If we take 0 away from 40, we end up 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 13:
If we divide 400 by 113, we get 3 and a remainder of 61.
Put 3 as the next digit of the answer. 
Result so far: 588389.29203
If we subtract 339 from 400, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Let's proceed to step 14:
113 can be fit into 610 5 times, resulting in a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 588389.292035
If we take 565 away from 610, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 15:
If we divide 450 by 113, we get 3 and a remainder of 111.
The number 3 becomes the next digit in our result. 
Result so far: 588389.2920353
If we take 339 away from 450, we end up with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

On to step 16:
113 can be fit into 1110 9 times, resulting in a remainder of 93.
Put 9 as the next digit of the answer. 
Result so far: 588389.29203539
Subtracting 1017 from 1110 leaves us with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

The final result is 588389.29203539 with a remainder of 9.3e-08.
