74290782 ÷ 89 
The aim is to understand the frequency of 89 in 74290782.

Let's proceed to step 1:
When dividing 7 by 89, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 89

On to step 2:
When dividing 74 by 89, we get 0 with a remainder of 74.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 74, we get 74.
Fetch the next digit (2) from the dividend, attach it to 74 and continue: 742 / 89

Step 3:
The number 89 fits into 742 8 times, leaving a remainder of 30.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 712 from 742 leaves us with 30.
Grab the next digit (9) from the dividend, add it to 30, then carry on: 309 / 89

Step 4:
The number 89 fits into 309 3 times, leaving a remainder of 42.
The next digit of our result is 3. 
Result so far: 83.0
Deduct 267 from 309 and we're left with 42.
Take the next digit (0) from the dividend and append it to 42, then repeat: 420 / 89

Going ahead to step 5:
The number 89 fits into 420 4 times, leaving a remainder of 64.
The next digit of our result is 4. 
Result so far: 834.0
Subtract 356 from 420 to get 64.
Take the next digit (7) from the dividend and append it to 64, then repeat: 647 / 89

Step 6:
647 divided by 89 is 7 with a remainder of 24.
Write down 7 as next digit of the result. 
Result so far: 8347.0
Subtracting 623 from 647 leaves us with 24.
Take the next digit (8) from the dividend and append it to 24, then repeat: 248 / 89

Advancing to step 7:
If we divide 248 by 89, we get 2 and a remainder of 70.
Put 2 as the next digit of the answer. 
Result so far: 83472.0
Subtracting 178 from 248 leaves us with 70.
Fetch the next digit (2) from the dividend, attach it to 70 and continue: 702 / 89

Let's proceed to step 8:
702 divided by 89 is 7 with a remainder of 79.
Write down 7 as next digit of the result. 
Result so far: 834727.0
Subtract 623 from 702 to get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

On to step 9:
89 goes into 790 8 times with a remainder of 78.
Record the quotient 8 as the next digit in the result. 
Result so far: 834727.8
Subtract 712 from 790 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 10:
The number 89 fits into 780 8 times, leaving a remainder of 68.
Put 8 as the next digit of the answer. 
Result so far: 834727.88
If we subtract 712 from 780, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

The quotient of the division is 834727.88, and the remainder is 0.068.
