We look at the division of 45054920 by 624 
The aim is to understand the frequency of 624 in 45054920.

On to step 1:
624 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 624

Going ahead to step 2:
624 goes into 45 0 times with a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 45 leaves us with 45.
Bring next digit (0) of the dividend behind the 45 and repeat the process: 450 / 624

Step 3:
624 can be fit into 450 0 times, resulting in a remainder of 450.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 450, we get 450.
Fetch the next digit (5) from the dividend, attach it to 450 and continue: 4505 / 624

Going ahead to step 4:
When dividing 4505 by 624, we get 7 with a remainder of 137.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 4368 from 4505, we get 137.
Grab the next digit (4) from the dividend, add it to 137, then carry on: 1374 / 624

Going ahead to step 5:
If we divide 1374 by 624, we get 2 and a remainder of 126.
The next digit of our result is 2. 
Result so far: 72.0
If we subtract 1248 from 1374, we get 126.
Bring next digit (9) of the dividend behind the 126 and repeat the process: 1269 / 624

Going ahead to step 6:
If we divide 1269 by 624, we get 2 and a remainder of 21.
Put 2 as the next digit of the answer. 
Result so far: 722.0
If we take 1248 away from 1269, we end up with 21.
Grab the next digit (2) from the dividend, add it to 21, then carry on: 212 / 624

Going ahead to step 7:
The number 624 fits into 212 0 times, leaving a remainder of 212.
The number 0 becomes the next digit in our result. 
Result so far: 7220.0
Subtracting 0 from 212 leaves us with 212.
Include the next digit (0) from the dividend after 212, then repeat: 2120 / 624

Advancing to step 8:
624 can be fit into 2120 3 times, resulting in a remainder of 248.
Write down 3 as next digit of the result. 
Result so far: 72203.0
Deduct 1872 from 2120 and we're left with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Advancing to step 9:
When dividing 2480 by 624, we get 3 with a remainder of 608.
The number 3 becomes the next digit in our result. 
Result so far: 72203.3
If we take 1872 away from 2480, we end up with 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Moving on to step 10:
When dividing 6080 by 624, we get 9 with a remainder of 464.
The next digit of our result is 9. 
Result so far: 72203.39
Subtracting 5616 from 6080 leaves us with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Moving on to step 11:
624 goes into 4640 7 times with a remainder of 272.
The next digit of our result is 7. 
Result so far: 72203.397
Subtract 4368 from 4640 to get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

On to step 12:
624 can be fit into 2720 4 times, resulting in a remainder of 224.
Use 4 as the next digit of our solution. 
Result so far: 72203.3974
The remainder is 224 after subtracting 2496 from 2720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Advancing to step 13:
When dividing 2240 by 624, we get 3 with a remainder of 368.
The next digit of our result is 3. 
Result so far: 72203.39743
The remainder is 368 after subtracting 1872 from 2240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Advancing to step 14:
624 can be fit into 3680 5 times, resulting in a remainder of 560.
Put 5 as the next digit of the answer. 
Result so far: 72203.397435
If we subtract 3120 from 3680, we get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Advancing to step 15:
When dividing 5600 by 624, we get 8 with a remainder of 608.
The number 8 becomes the next digit in our result. 
Result so far: 72203.3974358
Subtracting 4992 from 5600 leaves us with 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Going ahead to step 16:
When dividing 6080 by 624, we get 9 with a remainder of 464.
Put 9 as the next digit of the answer. 
Result so far: 72203.39743589
Subtract 5616 from 6080 to get 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Our division results in 72203.39743589 with a remaining 4.64e-07.
