We divide 669221 by 37
The aim is to understand the frequency of 37 in 669221.

On to step 1:
37 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 37

Step 2:
When dividing 66 by 37, we get 1 with a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 37 from 66 leaves us with 29.
Append the next digit (9) from the dividend to 29 and continue with: 299 / 37

On to step 3:
The number 37 fits into 299 8 times, leaving a remainder of 3.
The next digit of our result is 8. 
Result so far: 18.0
Deduct 296 from 299 and we're left with 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 37

Moving on to step 4:
37 can be fit into 32 0 times, resulting in a remainder of 32.
Put 0 as the next digit of the answer. 
Result so far: 180.0
Subtracting 0 from 32 leaves us with 32.
Grab the next digit (2) from the dividend, add it to 32, then carry on: 322 / 37

Step 5:
When dividing 322 by 37, we get 8 with a remainder of 26.
The number 8 becomes the next digit in our result. 
Result so far: 1808.0
If we subtract 296 from 322, we get 26.
Append the next digit (1) from the dividend to 26 and continue with: 261 / 37

Step 6:
If we divide 261 by 37, we get 7 and a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 18087.0
Subtracting 259 from 261 leaves us with 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 7:
The number 37 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 18087.0
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
If we divide 200 by 37, we get 5 and a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 18087.05
Subtracting 185 from 200 leaves us 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.

Moving on to step 9:
When dividing 150 by 37, we get 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 18087.054
The remainder is 2 after subtracting 148 from 150.
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 10:
37 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 18087.054
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 11:
37 goes into 200 5 times with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 18087.05405
If we subtract 185 from 200, we 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.

On to step 12:
When dividing 150 by 37, we get 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 18087.054054
If we take 148 away from 150, we end up with 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 13:
If we divide 20 by 37, we get 0 and a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 18087.054054
If we subtract 0 from 20, we 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.

Moving on to step 14:
When dividing 200 by 37, we get 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 18087.05405405
If we subtract 185 from 200, we 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.

Our division results in 18087.05405405 with a remaining 1.5e-08.
