We divide 515597 by 37
The aim is to understand the frequency of 37 in 515597.

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
If we take 0 away from 5, we end up with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 37

Step 2:
37 can be fit into 51 1 times, resulting in a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 14 after subtracting 37 from 51.
Fetch the next digit (5) from the dividend, attach it to 14 and continue: 145 / 37

Step 3:
37 goes into 145 3 times with a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Deduct 111 from 145 and we're left with 34.
Grab the next digit (5) from the dividend, add it to 34, then carry on: 345 / 37

Going ahead to step 4:
345 divided by 37 is 9 with a remainder of 12.
Record the quotient 9 as the next digit in the result. 
Result so far: 139.0
Subtracting 333 from 345 leaves us with 12.
Fetch the next digit (9) from the dividend, attach it to 12 and continue: 129 / 37

Advancing to step 5:
If we divide 129 by 37, we get 3 and a remainder of 18.
The number 3 becomes the next digit in our result. 
Result so far: 1393.0
Subtracting 111 from 129 leaves us with 18.
Bring next digit (7) of the dividend behind the 18 and repeat the process: 187 / 37

Advancing to step 6:
37 goes into 187 5 times with a remainder of 2.
The next digit of our result is 5. 
Result so far: 13935.0
Subtracting 185 from 187 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 7:
When dividing 20 by 37, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 13935.0
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
If we divide 200 by 37, we get 5 and a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 13935.05
The remainder is 15 after subtracting 185 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 9:
When dividing 150 by 37, we get 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 13935.054
The remainder is 2 after subtracting 148 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 10:
The number 37 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 13935.054
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 11:
When dividing 200 by 37, we get 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 13935.05405
Deduct 185 from 200 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 12:
If we divide 150 by 37, we get 4 and a remainder of 2.
The next digit of our result is 4. 
Result so far: 13935.054054
Subtracting 148 from 150 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 13:
37 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 13935.054054
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 14:
37 goes into 200 5 times with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 13935.05405405
The remainder is 15 after subtracting 185 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The quotient of the division is 13935.05405405, and the remainder is 1.5e-08.
