We look at the division of 375426 by 37 
The aim is to understand the frequency of 37 in 375426.

Moving on to step 1:
If we divide 3 by 37, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 37

Let's proceed to step 2:
37 goes into 37 1 times with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 0 after subtracting 37 from 37.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 37

Moving on to step 3:
When dividing 5 by 37, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 37

Going ahead to step 4:
The number 37 fits into 54 1 times, leaving a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 101.0
Deduct 37 from 54 and we're left with 17.
Grab the next digit (2) from the dividend, add it to 17, then carry on: 172 / 37

On to step 5:
37 can be fit into 172 4 times, resulting in a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 1014.0
If we take 148 away from 172, we end up with 24.
Bring next digit (6) of the dividend behind the 24 and repeat the process: 246 / 37

Step 6:
37 goes into 246 6 times with a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 10146.0
The remainder is 24 after subtracting 222 from 246.
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 7:
37 goes into 240 6 times with a remainder of 18.
Use 6 as the next digit of our solution. 
Result so far: 10146.6
If we take 222 away from 240, we end up with 18.
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 8:
37 goes into 180 4 times with a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 10146.64
Subtract 148 from 180 to 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.

On to step 9:
37 goes into 320 8 times with a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 10146.648
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.

Moving on to step 10:
The number 37 fits into 240 6 times, leaving a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 10146.6486
If we take 222 away from 240, we end up with 18.
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:
180 divided by 37 is 4 with a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 10146.64864
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.

Advancing to step 12:
If we divide 320 by 37, we get 8 and a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 10146.648648
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.

On to step 13:
If we divide 240 by 37, we get 6 and a remainder of 18.
The next digit of our result is 6. 
Result so far: 10146.6486486
If we take 222 away from 240, we end up with 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 14:
37 can be fit into 180 4 times, resulting in a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 10146.64864864
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 10146.64864864, with a leftover of 3.2e-08.
