We're dividing 348563 by 37 
The aim is to understand the frequency of 37 in 348563.

Step 1:
If we divide 3 by 37, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 37

Moving on to step 2:
If we divide 34 by 37, we get 0 and a remainder of 34.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 34, we get 34.
Grab the next digit (8) from the dividend, add it to 34, then carry on: 348 / 37

On to step 3:
37 can be fit into 348 9 times, resulting in a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 333 from 348, we get 15.
Grab the next digit (5) from the dividend, add it to 15, then carry on: 155 / 37

Step 4:
37 goes into 155 4 times with a remainder of 7.
Use 4 as the next digit of our solution. 
Result so far: 94.0
If we take 148 away from 155, we end up with 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 37

Moving on to step 5:
37 can be fit into 76 2 times, resulting in a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 942.0
Deduct 74 from 76 and we're left with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 37

On to step 6:
37 can be fit into 23 0 times, resulting in a remainder of 23.
Record the quotient 0 as the next digit in the result. 
Result so far: 9420.0
If we take 0 away from 23, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 7:
37 goes into 230 6 times with a remainder of 8.
The next digit of our result is 6. 
Result so far: 9420.6
The remainder is 8 after subtracting 222 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 8:
37 can be fit into 80 2 times, resulting in a remainder of 6.
The next digit of our result is 2. 
Result so far: 9420.62
Subtract 74 from 80 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 9:
If we divide 60 by 37, we get 1 and a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 9420.621
Subtracting 37 from 60 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 10:
When dividing 230 by 37, we get 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 9420.6216
Deduct 222 from 230 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 11:
80 divided by 37 is 2 with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 9420.62162
If we subtract 74 from 80, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 12:
37 can be fit into 60 1 times, resulting in a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 9420.621621
Subtract 37 from 60 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 13:
The number 37 fits into 230 6 times, leaving a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 9420.6216216
Subtract 222 from 230 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 14:
37 goes into 80 2 times with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 9420.62162162
If we take 74 away from 80, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final outcome is 9420.62162162, with a leftover of 6e-09.
