749421 ÷ 79 
The aim is to understand the frequency of 79 in 749421.

Advancing to step 1:
When dividing 7 by 79, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 79

Step 2:
When dividing 74 by 79, we get 0 with a remainder of 74.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 74 to get 74.
Append the next digit (9) from the dividend to 74 and continue with: 749 / 79

Moving on to step 3:
The number 79 fits into 749 9 times, leaving a remainder of 38.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 711 from 749 to get 38.
Bring next digit (4) of the dividend behind the 38 and repeat the process: 384 / 79

Moving on to step 4:
The number 79 fits into 384 4 times, leaving a remainder of 68.
Record the quotient 4 as the next digit in the result. 
Result so far: 94.0
If we take 316 away from 384, we end up with 68.
Fetch the next digit (2) from the dividend, attach it to 68 and continue: 682 / 79

On to step 5:
When dividing 682 by 79, we get 8 with a remainder of 50.
The next digit of our result is 8. 
Result so far: 948.0
If we subtract 632 from 682, we get 50.
Include the next digit (1) from the dividend after 50, then repeat: 501 / 79

Step 6:
501 divided by 79 is 6 with a remainder of 27.
The next digit of our result is 6. 
Result so far: 9486.0
If we subtract 474 from 501, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 7:
If we divide 270 by 79, we get 3 and a remainder of 33.
The number 3 becomes the next digit in our result. 
Result so far: 9486.3
If we subtract 237 from 270, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 8:
79 goes into 330 4 times with a remainder of 14.
The next digit of our result is 4. 
Result so far: 9486.34
Deduct 316 from 330 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 9:
79 can be fit into 140 1 times, resulting in a remainder of 61.
Use 1 as the next digit of our solution. 
Result so far: 9486.341
If we take 79 away from 140, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 10:
610 divided by 79 is 7 with a remainder of 57.
Use 7 as the next digit of our solution. 
Result so far: 9486.3417
If we subtract 553 from 610, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 11:
79 can be fit into 570 7 times, resulting in a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 9486.34177
The remainder is 17 after subtracting 553 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

In conclusion, the division gives 9486.34177 with a balance of 1.7e-05.
