We're dividing 85488943 by 624 
The aim is to understand the frequency of 624 in 85488943.

Moving on to step 1:
The number 624 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 624

Let's proceed to step 2:
85 divided by 624 is 0 with a remainder of 85.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 85 and we're left with 85.
Take the next digit (4) from the dividend and append it to 85, then repeat: 854 / 624

Moving on to step 3:
624 goes into 854 1 times with a remainder of 230.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 230 after subtracting 624 from 854.
Take the next digit (8) from the dividend and append it to 230, then repeat: 2308 / 624

Step 4:
The number 624 fits into 2308 3 times, leaving a remainder of 436.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Deduct 1872 from 2308 and we're left with 436.
Grab the next digit (8) from the dividend, add it to 436, then carry on: 4368 / 624

Let's proceed to step 5:
If we divide 4368 by 624, we get 7 and a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 137.0
If we take 4368 away from 4368, we end up with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 624

Let's proceed to step 6:
If we divide 9 by 624, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 1370.0
Subtracting 0 from 9 leaves us with 9.
Include the next digit (4) from the dividend after 9, then repeat: 94 / 624

Let's proceed to step 7:
If we divide 94 by 624, we get 0 and a remainder of 94.
Use 0 as the next digit of our solution. 
Result so far: 13700.0
Subtract 0 from 94 to get 94.
Grab the next digit (3) from the dividend, add it to 94, then carry on: 943 / 624

Moving on to step 8:
624 goes into 943 1 times with a remainder of 319.
Put 1 as the next digit of the answer. 
Result so far: 137001.0
If we take 624 away from 943, we end up with 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

Let's proceed to step 9:
If we divide 3190 by 624, we get 5 and a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 137001.5
If we subtract 3120 from 3190, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 10:
624 goes into 700 1 times with a remainder of 76.
Write down 1 as next digit of the result. 
Result so far: 137001.51
Deduct 624 from 700 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 11:
624 can be fit into 760 1 times, resulting in a remainder of 136.
The next digit of our result is 1. 
Result so far: 137001.511
The remainder is 136 after subtracting 624 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

After the division, we end up with 137001.511 and a remainder of 0.0136.
