We're dividing 139098 by 37 
The aim is to understand the frequency of 37 in 139098.

Step 1:
The number 37 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 37

Going ahead to step 2:
37 can be fit into 13 0 times, resulting in a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Take the next digit (9) from the dividend and append it to 13, then repeat: 139 / 37

Moving on to step 3:
If we divide 139 by 37, we get 3 and a remainder of 28.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 111 from 139 leaves us with 28.
Take the next digit (0) from the dividend and append it to 28, then repeat: 280 / 37

Advancing to step 4:
If we divide 280 by 37, we get 7 and a remainder of 21.
Record the quotient 7 as the next digit in the result. 
Result so far: 37.0
The remainder is 21 after subtracting 259 from 280.
Include the next digit (9) from the dividend after 21, then repeat: 219 / 37

On to step 5:
37 goes into 219 5 times with a remainder of 34.
Write down 5 as next digit of the result. 
Result so far: 375.0
Deduct 185 from 219 and we're left with 34.
Take the next digit (8) from the dividend and append it to 34, then repeat: 348 / 37

Going ahead to step 6:
37 can be fit into 348 9 times, resulting in a remainder of 15.
Record the quotient 9 as the next digit in the result. 
Result so far: 3759.0
Subtract 333 from 348 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 7:
150 divided by 37 is 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 3759.4
Subtract 148 from 150 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
37 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 3759.4
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
The number 37 fits into 200 5 times, leaving a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 3759.405
Subtract 185 from 200 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 10:
When dividing 150 by 37, we get 4 with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 3759.4054
Subtract 148 from 150 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 11:
The number 37 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 3759.4054
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 12:
37 goes into 200 5 times with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 3759.405405
Deduct 185 from 200 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 13:
37 goes into 150 4 times with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 3759.4054054
If we subtract 148 from 150, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 14:
If we divide 20 by 37, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 3759.4054054
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 3759.4054054 and a remainder of 2e-08.
