We look at the division of 902211 by 37 
The aim is to understand the frequency of 37 in 902211.

Step 1:
The number 37 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 37

Step 2:
When dividing 90 by 37, we get 2 with a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 74 away from 90, we end up with 16.
Take the next digit (2) from the dividend and append it to 16, then repeat: 162 / 37

Advancing to step 3:
162 divided by 37 is 4 with a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
Deduct 148 from 162 and we're left with 14.
Grab the next digit (2) from the dividend, add it to 14, then carry on: 142 / 37

Step 4:
37 goes into 142 3 times with a remainder of 31.
Write down 3 as next digit of the result. 
Result so far: 243.0
If we subtract 111 from 142, we get 31.
Take the next digit (1) from the dividend and append it to 31, then repeat: 311 / 37

Advancing to step 5:
37 goes into 311 8 times with a remainder of 15.
Use 8 as the next digit of our solution. 
Result so far: 2438.0
Deduct 296 from 311 and we're left with 15.
Include the next digit (1) from the dividend after 15, then repeat: 151 / 37

Advancing to step 6:
37 can be fit into 151 4 times, resulting in a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 24384.0
Subtracting 148 from 151 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
37 can be fit into 30 0 times, resulting in a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 24384.0
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
When dividing 300 by 37, we get 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 24384.08
If we take 296 away from 300, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
When dividing 40 by 37, we get 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 24384.081
The remainder is 3 after subtracting 37 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 10:
When dividing 30 by 37, we get 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 24384.081
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 11:
37 can be fit into 300 8 times, resulting in a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 24384.08108
Subtract 296 from 300 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 12:
37 goes into 40 1 times with a remainder of 3.
The next digit of our result is 1. 
Result so far: 24384.081081
The remainder is 3 after subtracting 37 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 13:
37 goes into 30 0 times with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 24384.081081
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 14:
300 divided by 37 is 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 24384.08108108
Deduct 296 from 300 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 24384.08108108, with a leftover of 4e-09.
