Let's divide 624691 by 79
The aim is to understand the frequency of 79 in 624691.

Going ahead to step 1:
The number 79 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 79

Moving on to step 2:
79 can be fit into 62 0 times, resulting in 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.
Grab the next digit (4) from the dividend, add it to 62, then carry on: 624 / 79

Moving on to step 3:
79 can be fit into 624 7 times, resulting in a remainder of 71.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 553 from 624, we get 71.
Bring next digit (6) of the dividend behind the 71 and repeat the process: 716 / 79

Advancing to step 4:
716 divided by 79 is 9 with a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 79.0
If we subtract 711 from 716, we get 5.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 79

Step 5:
If we divide 59 by 79, we get 0 and a remainder of 59.
Put 0 as the next digit of the answer. 
Result so far: 790.0
Subtract 0 from 59 to get 59.
Bring next digit (1) of the dividend behind the 59 and repeat the process: 591 / 79

Step 6:
If we divide 591 by 79, we get 7 and a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 7907.0
Deduct 553 from 591 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 7:
380 divided by 79 is 4 with a remainder of 64.
Record the quotient 4 as the next digit in the result. 
Result so far: 7907.4
Deduct 316 from 380 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.

On to step 8:
The number 79 fits into 640 8 times, leaving a remainder of 8.
The next digit of our result is 8. 
Result so far: 7907.48
Subtract 632 from 640 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
79 goes into 80 1 times with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 7907.481
Deduct 79 from 80 and we're left 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 10:
79 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 7907.481
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 11:
When dividing 100 by 79, we get 1 with a remainder of 21.
The next digit of our result is 1. 
Result so far: 7907.48101
If we subtract 79 from 100, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 12:
79 can be fit into 210 2 times, resulting in a remainder of 52.
The number 2 becomes the next digit in our result. 
Result so far: 7907.481012
Subtracting 158 from 210 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 13:
79 goes into 520 6 times with a remainder of 46.
The next digit of our result is 6. 
Result so far: 7907.4810126
Subtracting 474 from 520 leaves us 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.

Advancing to step 14:
79 can be fit into 460 5 times, resulting in a remainder of 65.
Put 5 as the next digit of the answer. 
Result so far: 7907.48101265
If we take 395 away from 460, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The final result is 7907.48101265 with a remainder of 6.5e-08.
