We look at the division of 79393179 by 624 
The aim is to understand the frequency of 624 in 79393179.

Going ahead to step 1:
7 divided by 624 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 624

Step 2:
The number 624 fits into 79 0 times, leaving a remainder of 79.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 79 and we're left with 79.
Grab the next digit (3) from the dividend, add it to 79, then carry on: 793 / 624

Let's proceed to step 3:
624 goes into 793 1 times with a remainder of 169.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 624 from 793 and we're left with 169.
Take the next digit (9) from the dividend and append it to 169, then repeat: 1699 / 624

On to step 4:
624 can be fit into 1699 2 times, resulting in a remainder of 451.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 451 after subtracting 1248 from 1699.
Take the next digit (3) from the dividend and append it to 451, then repeat: 4513 / 624

On to step 5:
If we divide 4513 by 624, we get 7 and a remainder of 145.
The next digit of our result is 7. 
Result so far: 127.0
Subtract 4368 from 4513 to get 145.
Take the next digit (1) from the dividend and append it to 145, then repeat: 1451 / 624

Let's proceed to step 6:
624 goes into 1451 2 times with a remainder of 203.
Write down 2 as next digit of the result. 
Result so far: 1272.0
Deduct 1248 from 1451 and we're left with 203.
Take the next digit (7) from the dividend and append it to 203, then repeat: 2037 / 624

On to step 7:
When dividing 2037 by 624, we get 3 with a remainder of 165.
The number 3 becomes the next digit in our result. 
Result so far: 12723.0
Subtract 1872 from 2037 to get 165.
Bring next digit (9) of the dividend behind the 165 and repeat the process: 1659 / 624

Step 8:
If we divide 1659 by 624, we get 2 and a remainder of 411.
Write down 2 as next digit of the result. 
Result so far: 127232.0
Deduct 1248 from 1659 and we're left with 411.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4110, and continue the process.

Let's proceed to step 9:
When dividing 4110 by 624, we get 6 with a remainder of 366.
Put 6 as the next digit of the answer. 
Result so far: 127232.6
Subtracting 3744 from 4110 leaves us with 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Moving on to step 10:
When dividing 3660 by 624, we get 5 with a remainder of 540.
Put 5 as the next digit of the answer. 
Result so far: 127232.65
If we subtract 3120 from 3660, we get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Advancing to step 11:
When dividing 5400 by 624, we get 8 with a remainder of 408.
The next digit of our result is 8. 
Result so far: 127232.658
Subtract 4992 from 5400 to get 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Advancing to step 12:
If we divide 4080 by 624, we get 6 and a remainder of 336.
Put 6 as the next digit of the answer. 
Result so far: 127232.6586
The remainder is 336 after subtracting 3744 from 4080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Moving on to step 13:
3360 divided by 624 is 5 with a remainder of 240.
Write down 5 as next digit of the result. 
Result so far: 127232.65865
Deduct 3120 from 3360 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 14:
624 goes into 2400 3 times with a remainder of 528.
Put 3 as the next digit of the answer. 
Result so far: 127232.658653
Subtract 1872 from 2400 to get 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Advancing to step 15:
The number 624 fits into 5280 8 times, leaving a remainder of 288.
Write down 8 as next digit of the result. 
Result so far: 127232.6586538
If we take 4992 away from 5280, we end up with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

On to step 16:
If we divide 2880 by 624, we get 4 and a remainder of 384.
The number 4 becomes the next digit in our result. 
Result so far: 127232.65865384
Deduct 2496 from 2880 and we're left with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

The quotient of the division is 127232.65865384, and the remainder is 3.84e-07.
