574372 divided by 37 
The aim is to understand the frequency of 37 in 574372.

Step 1:
If we divide 5 by 37, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 37

On to step 2:
When dividing 57 by 37, we get 1 with a remainder of 20.
The next digit of our result is 1. 
Result so far: 1.0
If we take 37 away from 57, we end up with 20.
Take the next digit (4) from the dividend and append it to 20, then repeat: 204 / 37

Advancing to step 3:
37 can be fit into 204 5 times, resulting in a remainder of 19.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Deduct 185 from 204 and we're left with 19.
Fetch the next digit (3) from the dividend, attach it to 19 and continue: 193 / 37

Moving on to step 4:
193 divided by 37 is 5 with a remainder of 8.
Use 5 as the next digit of our solution. 
Result so far: 155.0
Subtracting 185 from 193 leaves us with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 37

On to step 5:
If we divide 87 by 37, we get 2 and a remainder of 13.
Record the quotient 2 as the next digit in the result. 
Result so far: 1552.0
Subtracting 74 from 87 leaves us with 13.
Take the next digit (2) from the dividend and append it to 13, then repeat: 132 / 37

Let's proceed to step 6:
37 can be fit into 132 3 times, resulting in a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 15523.0
Deduct 111 from 132 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.

Step 7:
210 divided by 37 is 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 15523.5
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.

Let's proceed to step 8:
37 goes into 250 6 times with a remainder of 28.
Put 6 as the next digit of the answer. 
Result so far: 15523.56
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 9:
The number 37 fits into 280 7 times, leaving a remainder of 21.
Put 7 as the next digit of the answer. 
Result so far: 15523.567
Subtracting 259 from 280 leaves us 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.

On to step 10:
If we divide 210 by 37, we get 5 and a remainder of 25.
The next digit of our result is 5. 
Result so far: 15523.5675
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.

Step 11:
The number 37 fits into 250 6 times, leaving a remainder of 28.
Put 6 as the next digit of the answer. 
Result so far: 15523.56756
If we subtract 222 from 250, we get 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 12:
If we divide 280 by 37, we get 7 and a remainder of 21.
The number 7 becomes the next digit in our result. 
Result so far: 15523.567567
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.

Moving on to step 13:
37 can be fit into 210 5 times, resulting in a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 15523.5675675
Deduct 185 from 210 and we're left 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.

Going ahead to step 14:
250 divided by 37 is 6 with a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 15523.56756756
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.

The quotient of the division is 15523.56756756, and the remainder is 2.8e-08.
