We're dividing 572443 by 37 
The aim is to understand the frequency of 37 in 572443.

On to step 1:
When dividing 5 by 37, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 37

Moving on to step 2:
37 goes into 57 1 times with a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 37 from 57 leaves us with 20.
Fetch the next digit (2) from the dividend, attach it to 20 and continue: 202 / 37

Step 3:
37 can be fit into 202 5 times, resulting in a remainder of 17.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we subtract 185 from 202, we get 17.
Append the next digit (4) from the dividend to 17 and continue with: 174 / 37

On to step 4:
37 goes into 174 4 times with a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 154.0
The remainder is 26 after subtracting 148 from 174.
Take the next digit (4) from the dividend and append it to 26, then repeat: 264 / 37

On to step 5:
37 goes into 264 7 times with a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 1547.0
If we take 259 away from 264, we end up with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 37

Moving on to step 6:
If we divide 53 by 37, we get 1 and a remainder of 16.
The next digit of our result is 1. 
Result so far: 15471.0
Subtract 37 from 53 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 7:
If we divide 160 by 37, we get 4 and a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 15471.4
Deduct 148 from 160 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 8:
120 divided by 37 is 3 with a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 15471.43
Subtract 111 from 120 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 9:
When dividing 90 by 37, we get 2 with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 15471.432
Subtract 74 from 90 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 10:
When dividing 160 by 37, we get 4 with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 15471.4324
Subtracting 148 from 160 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 11:
The number 37 fits into 120 3 times, leaving a remainder of 9.
The next digit of our result is 3. 
Result so far: 15471.43243
Subtracting 111 from 120 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 12:
37 goes into 90 2 times with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 15471.432432
If we take 74 away from 90, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 13:
The number 37 fits into 160 4 times, leaving a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 15471.4324324
Subtracting 148 from 160 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 14:
When dividing 120 by 37, we get 3 with a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 15471.43243243
Subtracting 111 from 120 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The final result is 15471.43243243 with a remainder of 9e-09.
