624881 ÷ 37 
The aim is to understand the frequency of 37 in 624881.

Step 1:
When dividing 6 by 37, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 37

Advancing to step 2:
When dividing 62 by 37, we get 1 with a remainder of 25.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 37 from 62 and we're left with 25.
Take the next digit (4) from the dividend and append it to 25, then repeat: 254 / 37

Let's proceed to step 3:
37 goes into 254 6 times with a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 16.0
Deduct 222 from 254 and we're left with 32.
Fetch the next digit (8) from the dividend, attach it to 32 and continue: 328 / 37

Let's proceed to step 4:
328 divided by 37 is 8 with a remainder of 32.
The next digit of our result is 8. 
Result so far: 168.0
If we subtract 296 from 328, we get 32.
Bring next digit (8) of the dividend behind the 32 and repeat the process: 328 / 37

Going ahead to step 5:
The number 37 fits into 328 8 times, leaving a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 1688.0
The remainder is 32 after subtracting 296 from 328.
Fetch the next digit (1) from the dividend, attach it to 32 and continue: 321 / 37

On to step 6:
The number 37 fits into 321 8 times, leaving a remainder of 25.
The number 8 becomes the next digit in our result. 
Result so far: 16888.0
If we take 296 away from 321, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 7:
37 can be fit into 250 6 times, resulting in a remainder of 28.
Put 6 as the next digit of the answer. 
Result so far: 16888.6
The remainder is 28 after subtracting 222 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 8:
37 goes into 280 7 times with a remainder of 21.
Write down 7 as next digit of the result. 
Result so far: 16888.67
If we take 259 away from 280, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 9:
210 divided by 37 is 5 with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 16888.675
If we take 185 away from 210, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 10:
37 can be fit into 250 6 times, resulting in a remainder of 28.
Put 6 as the next digit of the answer. 
Result so far: 16888.6756
The remainder is 28 after subtracting 222 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 11:
When dividing 280 by 37, we get 7 with a remainder of 21.
Write down 7 as next digit of the result. 
Result so far: 16888.67567
If we take 259 away from 280, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 12:
210 divided by 37 is 5 with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 16888.675675
The remainder is 25 after subtracting 185 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 13:
37 can be fit into 250 6 times, resulting in a remainder of 28.
The number 6 becomes the next digit in our result. 
Result so far: 16888.6756756
Subtracting 222 from 250 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 14:
37 can be fit into 280 7 times, resulting in a remainder of 21.
The number 7 becomes the next digit in our result. 
Result so far: 16888.67567567
Deduct 259 from 280 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

In conclusion, the division gives 16888.67567567 with a balance of 2.1e-08.
