We're dividing 86481 by 37 
The aim is to understand the frequency of 37 in 86481.

Advancing to step 1:
8 divided by 37 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 37

On to step 2:
86 divided by 37 is 2 with a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 74 from 86, we get 12.
Bring next digit (4) of the dividend behind the 12 and repeat the process: 124 / 37

Advancing to step 3:
The number 37 fits into 124 3 times, leaving a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 23.0
Deduct 111 from 124 and we're left with 13.
Fetch the next digit (8) from the dividend, attach it to 13 and continue: 138 / 37

Moving on to step 4:
When dividing 138 by 37, we get 3 with a remainder of 27.
Use 3 as the next digit of our solution. 
Result so far: 233.0
Deduct 111 from 138 and we're left with 27.
Append the next digit (1) from the dividend to 27 and continue with: 271 / 37

Step 5:
37 goes into 271 7 times with a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 2337.0
Deduct 259 from 271 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 6:
The number 37 fits into 120 3 times, leaving a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 2337.3
Subtract 111 from 120 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
37 goes into 90 2 times with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 2337.32
If we take 74 away from 90, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 8:
The number 37 fits into 160 4 times, leaving a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 2337.324
Deduct 148 from 160 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 9:
120 divided by 37 is 3 with a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 2337.3243
The remainder is 9 after subtracting 111 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 10:
90 divided by 37 is 2 with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 2337.32432
The remainder is 16 after subtracting 74 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 11:
When dividing 160 by 37, we get 4 with a remainder of 12.
The next digit of our result is 4. 
Result so far: 2337.324324
Deduct 148 from 160 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 12:
120 divided by 37 is 3 with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 2337.3243243
Subtract 111 from 120 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 13:
37 goes into 90 2 times with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 2337.32432432
If we take 74 away from 90, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 2337.32432432, with a leftover of 1.6e-08.
