628983 ÷ 79 
The aim is to understand the frequency of 79 in 628983.

Moving on to step 1:
The number 79 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 79

Moving on to step 2:
The number 79 fits into 62 0 times, leaving a remainder of 62.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 62 and we're left with 62.
Take the next digit (8) from the dividend and append it to 62, then repeat: 628 / 79

Step 3:
If we divide 628 by 79, we get 7 and a remainder of 75.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 553 away from 628, we end up with 75.
Bring next digit (9) of the dividend behind the 75 and repeat the process: 759 / 79

Let's proceed to step 4:
When dividing 759 by 79, we get 9 with a remainder of 48.
Record the quotient 9 as the next digit in the result. 
Result so far: 79.0
If we subtract 711 from 759, we get 48.
Fetch the next digit (8) from the dividend, attach it to 48 and continue: 488 / 79

On to step 5:
The number 79 fits into 488 6 times, leaving a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 796.0
The remainder is 14 after subtracting 474 from 488.
Take the next digit (3) from the dividend and append it to 14, then repeat: 143 / 79

Step 6:
When dividing 143 by 79, we get 1 with a remainder of 64.
Use 1 as the next digit of our solution. 
Result so far: 7961.0
Deduct 79 from 143 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 7:
640 divided by 79 is 8 with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 7961.8
The remainder is 8 after subtracting 632 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 8:
79 can be fit into 80 1 times, resulting in a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 7961.81
If we take 79 away from 80, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 9:
When dividing 10 by 79, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 7961.81
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 10:
The number 79 fits into 100 1 times, leaving a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 7961.8101
If we take 79 away from 100, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 11:
When dividing 210 by 79, we get 2 with a remainder of 52.
The number 2 becomes the next digit in our result. 
Result so far: 7961.81012
If we subtract 158 from 210, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 12:
The number 79 fits into 520 6 times, leaving a remainder of 46.
Use 6 as the next digit of our solution. 
Result so far: 7961.810126
Deduct 474 from 520 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 13:
When dividing 460 by 79, we get 5 with a remainder of 65.
The next digit of our result is 5. 
Result so far: 7961.8101265
Subtract 395 from 460 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 14:
79 goes into 650 8 times with a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 7961.81012658
If we take 632 away from 650, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final outcome is 7961.81012658, with a leftover of 1.8e-08.
