Let's divide 7119982 by 624
The aim is to understand the frequency of 624 in 7119982.

Step 1:
When dividing 7 by 624, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 624

Moving on to step 2:
If we divide 71 by 624, we get 0 and a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 71 and we're left with 71.
Append the next digit (1) from the dividend to 71 and continue with: 711 / 624

Going ahead to step 3:
711 divided by 624 is 1 with a remainder of 87.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 87 after subtracting 624 from 711.
Take the next digit (9) from the dividend and append it to 87, then repeat: 879 / 624

On to step 4:
879 divided by 624 is 1 with a remainder of 255.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we subtract 624 from 879, we get 255.
Take the next digit (9) from the dividend and append it to 255, then repeat: 2559 / 624

Advancing to step 5:
The number 624 fits into 2559 4 times, leaving a remainder of 63.
Put 4 as the next digit of the answer. 
Result so far: 114.0
Subtracting 2496 from 2559 leaves us with 63.
Append the next digit (8) from the dividend to 63 and continue with: 638 / 624

Let's proceed to step 6:
If we divide 638 by 624, we get 1 and a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 1141.0
The remainder is 14 after subtracting 624 from 638.
Take the next digit (2) from the dividend and append it to 14, then repeat: 142 / 624

Advancing to step 7:
624 can be fit into 142 0 times, resulting in a remainder of 142.
Record the quotient 0 as the next digit in the result. 
Result so far: 11410.0
If we take 0 away from 142, we end up with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Let's proceed to step 8:
When dividing 1420 by 624, we get 2 with a remainder of 172.
Use 2 as the next digit of our solution. 
Result so far: 11410.2
Subtract 1248 from 1420 to get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Going ahead to step 9:
When dividing 1720 by 624, we get 2 with a remainder of 472.
Record the quotient 2 as the next digit in the result. 
Result so far: 11410.22
If we take 1248 away from 1720, we end up with 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

The final outcome is 11410.22, with a leftover of 0.472.
