We look at the division of 442100 by 37 
The aim is to understand the frequency of 37 in 442100.

On to step 1:
When dividing 4 by 37, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 37

On to step 2:
37 can be fit into 44 1 times, resulting in a remainder of 7.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 37 from 44 to get 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 37

Advancing to step 3:
72 divided by 37 is 1 with a remainder of 35.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtract 37 from 72 to get 35.
Grab the next digit (1) from the dividend, add it to 35, then carry on: 351 / 37

Let's proceed to step 4:
37 goes into 351 9 times with a remainder of 18.
The next digit of our result is 9. 
Result so far: 119.0
Deduct 333 from 351 and we're left with 18.
Append the next digit (0) from the dividend to 18 and continue with: 180 / 37

Let's proceed to step 5:
If we divide 180 by 37, we get 4 and a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 1194.0
If we take 148 away from 180, we end up with 32.
Include the next digit (0) from the dividend after 32, then repeat: 320 / 37

Let's proceed to step 6:
If we divide 320 by 37, we get 8 and a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 11948.0
Deduct 296 from 320 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 7:
37 goes into 240 6 times with a remainder of 18.
Record the quotient 6 as the next digit in the result. 
Result so far: 11948.6
Subtract 222 from 240 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 8:
If we divide 180 by 37, we get 4 and a remainder of 32.
The next digit of our result is 4. 
Result so far: 11948.64
If we subtract 148 from 180, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 9:
When dividing 320 by 37, we get 8 with a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 11948.648
If we take 296 away from 320, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 10:
If we divide 240 by 37, we get 6 and a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 11948.6486
The remainder is 18 after subtracting 222 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 11:
If we divide 180 by 37, we get 4 and a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 11948.64864
If we subtract 148 from 180, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 12:
The number 37 fits into 320 8 times, leaving a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 11948.648648
Subtract 296 from 320 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 13:
240 divided by 37 is 6 with a remainder of 18.
Record the quotient 6 as the next digit in the result. 
Result so far: 11948.6486486
The remainder is 18 after subtracting 222 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 14:
When dividing 180 by 37, we get 4 with a remainder of 32.
The next digit of our result is 4. 
Result so far: 11948.64864864
Deduct 148 from 180 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 11948.64864864, with a leftover of 3.2e-08.
