We look at the division of 7618169 by 624 
The aim is to understand the frequency of 624 in 7618169.

On to step 1:
If we divide 7 by 624, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 624

Let's proceed to step 2:
624 goes into 76 0 times with a remainder of 76.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 76 and we're left with 76.
Grab the next digit (1) from the dividend, add it to 76, then carry on: 761 / 624

Let's proceed to step 3:
624 can be fit into 761 1 times, resulting in a remainder of 137.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 624 from 761 and we're left with 137.
Fetch the next digit (8) from the dividend, attach it to 137 and continue: 1378 / 624

Advancing to step 4:
1378 divided by 624 is 2 with a remainder of 130.
Write down 2 as next digit of the result. 
Result so far: 12.0
The remainder is 130 after subtracting 1248 from 1378.
Bring next digit (1) of the dividend behind the 130 and repeat the process: 1301 / 624

Let's proceed to step 5:
1301 divided by 624 is 2 with a remainder of 53.
Put 2 as the next digit of the answer. 
Result so far: 122.0
If we take 1248 away from 1301, we end up with 53.
Fetch the next digit (6) from the dividend, attach it to 53 and continue: 536 / 624

Going ahead to step 6:
624 goes into 536 0 times with a remainder of 536.
The number 0 becomes the next digit in our result. 
Result so far: 1220.0
If we subtract 0 from 536, we get 536.
Fetch the next digit (9) from the dividend, attach it to 536 and continue: 5369 / 624

On to step 7:
624 can be fit into 5369 8 times, resulting in a remainder of 377.
Use 8 as the next digit of our solution. 
Result so far: 12208.0
If we subtract 4992 from 5369, we get 377.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

On to step 8:
The number 624 fits into 3770 6 times, leaving a remainder of 26.
The next digit of our result is 6. 
Result so far: 12208.6
Subtracting 3744 from 3770 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 9:
If we divide 260 by 624, we get 0 and a remainder of 260.
The number 0 becomes the next digit in our result. 
Result so far: 12208.6
The remainder is 260 after subtracting 0 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Going ahead to step 10:
624 can be fit into 2600 4 times, resulting in a remainder of 104.
Put 4 as the next digit of the answer. 
Result so far: 12208.604
Deduct 2496 from 2600 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Advancing to step 11:
1040 divided by 624 is 1 with a remainder of 416.
Put 1 as the next digit of the answer. 
Result so far: 12208.6041
Deduct 624 from 1040 and we're left with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Going ahead to step 12:
If we divide 4160 by 624, we get 6 and a remainder of 416.
Write down 6 as next digit of the result. 
Result so far: 12208.60416
The remainder is 416 after subtracting 3744 from 4160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Let's proceed to step 13:
The number 624 fits into 4160 6 times, leaving a remainder of 416.
Write down 6 as next digit of the result. 
Result so far: 12208.604166
The remainder is 416 after subtracting 3744 from 4160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

After the division, we end up with 12208.604166 and a remainder of 4.16e-05.
