Let's divide 438159 by 37
The aim is to understand the frequency of 37 in 438159.

Moving on to step 1:
37 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 37

Going ahead to step 2:
If we divide 43 by 37, we get 1 and a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 37 from 43 to get 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 37

Advancing to step 3:
When dividing 68 by 37, we get 1 with a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtract 37 from 68 to get 31.
Take the next digit (1) from the dividend and append it to 31, then repeat: 311 / 37

Going ahead to step 4:
311 divided by 37 is 8 with a remainder of 15.
The number 8 becomes the next digit in our result. 
Result so far: 118.0
If we take 296 away from 311, we end up with 15.
Grab the next digit (5) from the dividend, add it to 15, then carry on: 155 / 37

Advancing to step 5:
When dividing 155 by 37, we get 4 with a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 1184.0
If we take 148 away from 155, we end up with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 37

Step 6:
37 goes into 79 2 times with a remainder of 5.
Use 2 as the next digit of our solution. 
Result so far: 11842.0
The remainder is 5 after subtracting 74 from 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 7:
37 can be fit into 50 1 times, resulting in a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 11842.1
Subtract 37 from 50 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 8:
If we divide 130 by 37, we get 3 and a remainder of 19.
The number 3 becomes the next digit in our result. 
Result so far: 11842.13
Subtracting 111 from 130 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 9:
The number 37 fits into 190 5 times, leaving a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 11842.135
The remainder is 5 after subtracting 185 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 10:
37 can be fit into 50 1 times, resulting in a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 11842.1351
If we take 37 away from 50, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 11:
If we divide 130 by 37, we get 3 and a remainder of 19.
The next digit of our result is 3. 
Result so far: 11842.13513
Subtracting 111 from 130 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 12:
190 divided by 37 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 11842.135135
Subtracting 185 from 190 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 13:
37 can be fit into 50 1 times, resulting in a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 11842.1351351
The remainder is 13 after subtracting 37 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 14:
The number 37 fits into 130 3 times, leaving a remainder of 19.
The next digit of our result is 3. 
Result so far: 11842.13513513
Subtract 111 from 130 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

After the division, we end up with 11842.13513513 and a remainder of 1.9e-08.
