74790938 ÷ 66 
We want to figure out the number of times 74790938 can be divided by 66.

Advancing to step 1:
The number 66 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 66

Going ahead to step 2:
74 divided by 66 is 1 with a remainder of 8.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 66 from 74, we get 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 66

Step 3:
If we divide 87 by 66, we get 1 and a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Deduct 66 from 87 and we're left with 21.
Fetch the next digit (9) from the dividend, attach it to 21 and continue: 219 / 66

On to step 4:
66 can be fit into 219 3 times, resulting in a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 113.0
The remainder is 21 after subtracting 198 from 219.
Grab the next digit (0) from the dividend, add it to 21, then carry on: 210 / 66

Step 5:
When dividing 210 by 66, we get 3 with a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 1133.0
Subtract 198 from 210 to get 12.
Take the next digit (9) from the dividend and append it to 12, then repeat: 129 / 66

Advancing to step 6:
When dividing 129 by 66, we get 1 with a remainder of 63.
Put 1 as the next digit of the answer. 
Result so far: 11331.0
Subtract 66 from 129 to get 63.
Include the next digit (3) from the dividend after 63, then repeat: 633 / 66

Advancing to step 7:
The number 66 fits into 633 9 times, leaving a remainder of 39.
The number 9 becomes the next digit in our result. 
Result so far: 113319.0
If we take 594 away from 633, we end up with 39.
Fetch the next digit (8) from the dividend, attach it to 39 and continue: 398 / 66

Moving on to step 8:
The number 66 fits into 398 6 times, leaving a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 1133196.0
Deduct 396 from 398 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 9:
66 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 1133196.0
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 10:
If we divide 200 by 66, we get 3 and a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 1133196.03
Subtract 198 from 200 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 11:
66 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 1133196.03
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 12:
66 goes into 200 3 times with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 1133196.0303
Subtract 198 from 200 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 13:
66 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 1133196.0303
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 14:
If we divide 200 by 66, we get 3 and a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 1133196.030303
The remainder is 2 after subtracting 198 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 15:
66 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 1133196.030303
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 16:
200 divided by 66 is 3 with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 1133196.03030303
Subtracting 198 from 200 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final outcome is 1133196.03030303, with a leftover of 2e-09.
