We look at the division of 113870 by 37 
The aim is to understand the frequency of 37 in 113870.

Let's proceed to step 1:
1 divided by 37 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 37

Going ahead to step 2:
If we divide 11 by 37, we get 0 and a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 11 leaves us with 11.
Take the next digit (3) from the dividend and append it to 11, then repeat: 113 / 37

Going ahead to step 3:
37 goes into 113 3 times with a remainder of 2.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 111 from 113, we get 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 37

Advancing to step 4:
37 goes into 28 0 times with a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 30.0
Subtract 0 from 28 to get 28.
Grab the next digit (7) from the dividend, add it to 28, then carry on: 287 / 37

Step 5:
37 can be fit into 287 7 times, resulting in a remainder of 28.
Use 7 as the next digit of our solution. 
Result so far: 307.0
If we subtract 259 from 287, we get 28.
Include the next digit (0) from the dividend after 28, then repeat: 280 / 37

Step 6:
37 goes into 280 7 times with a remainder of 21.
The next digit of our result is 7. 
Result so far: 3077.0
Subtract 259 from 280 to get 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 7:
210 divided by 37 is 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 3077.5
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.

On to step 8:
250 divided by 37 is 6 with a remainder of 28.
Put 6 as the next digit of the answer. 
Result so far: 3077.56
If we take 222 away from 250, we end up 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.

Let's proceed to step 9:
37 goes into 280 7 times with a remainder of 21.
The next digit of our result is 7. 
Result so far: 3077.567
The remainder is 21 after subtracting 259 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 10:
210 divided by 37 is 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 3077.5675
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.

On to step 11:
37 can be fit into 250 6 times, resulting in a remainder of 28.
The next digit of our result is 6. 
Result so far: 3077.56756
Subtract 222 from 250 to 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:
37 goes into 280 7 times with a remainder of 21.
The number 7 becomes the next digit in our result. 
Result so far: 3077.567567
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.

Moving on to step 13:
37 can be fit into 210 5 times, resulting in a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 3077.5675675
If we subtract 185 from 210, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On 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: 3077.56756756
Deduct 222 from 250 and we're left 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 final result is 3077.56756756 with a remainder of 2.8e-08.
