We look at the division of 351128 by 37 
The aim is to understand the frequency of 37 in 351128.

Advancing to step 1:
If we divide 3 by 37, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 37

Step 2:
When dividing 35 by 37, we get 0 with a remainder of 35.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 35 leaves us with 35.
Grab the next digit (1) from the dividend, add it to 35, then carry on: 351 / 37

Going ahead to step 3:
When dividing 351 by 37, we get 9 with a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 9.0
The remainder is 18 after subtracting 333 from 351.
Append the next digit (1) from the dividend to 18 and continue with: 181 / 37

Moving on to step 4:
37 goes into 181 4 times with a remainder of 33.
Use 4 as the next digit of our solution. 
Result so far: 94.0
If we subtract 148 from 181, we get 33.
Bring next digit (2) of the dividend behind the 33 and repeat the process: 332 / 37

Let's proceed to step 5:
If we divide 332 by 37, we get 8 and a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 948.0
Deduct 296 from 332 and we're left with 36.
Fetch the next digit (8) from the dividend, attach it to 36 and continue: 368 / 37

Advancing to step 6:
37 goes into 368 9 times with a remainder of 35.
Use 9 as the next digit of our solution. 
Result so far: 9489.0
Subtract 333 from 368 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 7:
37 goes into 350 9 times with a remainder of 17.
Record the quotient 9 as the next digit in the result. 
Result so far: 9489.9
If we take 333 away from 350, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 8:
The number 37 fits into 170 4 times, leaving a remainder of 22.
Record the quotient 4 as the next digit in the result. 
Result so far: 9489.94
Subtract 148 from 170 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 9:
If we divide 220 by 37, we get 5 and a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 9489.945
If we take 185 away from 220, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 10:
37 goes into 350 9 times with a remainder of 17.
Record the quotient 9 as the next digit in the result. 
Result so far: 9489.9459
Subtract 333 from 350 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 11:
If we divide 170 by 37, we get 4 and a remainder of 22.
Record the quotient 4 as the next digit in the result. 
Result so far: 9489.94594
The remainder is 22 after subtracting 148 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 12:
If we divide 220 by 37, we get 5 and a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 9489.945945
The remainder is 35 after subtracting 185 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 13:
37 goes into 350 9 times with a remainder of 17.
The number 9 becomes the next digit in our result. 
Result so far: 9489.9459459
Deduct 333 from 350 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 14:
37 goes into 170 4 times with a remainder of 22.
Use 4 as the next digit of our solution. 
Result so far: 9489.94594594
If we subtract 148 from 170, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

In conclusion, the division gives 9489.94594594 with a balance of 2.2e-08.
