We're dividing 690880 by 37 
The aim is to understand the frequency of 37 in 690880.

Step 1:
37 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 37

Advancing to step 2:
The number 37 fits into 69 1 times, leaving a remainder of 32.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 37 from 69, we get 32.
Bring next digit (0) of the dividend behind the 32 and repeat the process: 320 / 37

Moving on to step 3:
If we divide 320 by 37, we get 8 and a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Subtract 296 from 320 to get 24.
Grab the next digit (8) from the dividend, add it to 24, then carry on: 248 / 37

Step 4:
When dividing 248 by 37, we get 6 with a remainder of 26.
The number 6 becomes the next digit in our result. 
Result so far: 186.0
If we subtract 222 from 248, we get 26.
Append the next digit (8) from the dividend to 26 and continue with: 268 / 37

On to step 5:
37 can be fit into 268 7 times, resulting in a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 1867.0
Deduct 259 from 268 and we're left with 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 37

Moving on to step 6:
37 goes into 90 2 times with a remainder of 16.
The next digit of our result is 2. 
Result so far: 18672.0
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.

Moving on to step 7:
37 goes into 160 4 times with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 18672.4
If we take 148 away from 160, we end up 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.

Advancing to step 8:
When dividing 120 by 37, we get 3 with a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 18672.43
Deduct 111 from 120 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 9:
90 divided by 37 is 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 18672.432
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.

Advancing to step 10:
When dividing 160 by 37, we get 4 with a remainder of 12.
The next digit of our result is 4. 
Result so far: 18672.4324
If we subtract 148 from 160, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 11:
120 divided by 37 is 3 with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 18672.43243
If we take 111 away from 120, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 12:
If we divide 90 by 37, we get 2 and a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 18672.432432
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.

Going ahead to step 13:
37 goes into 160 4 times with a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 18672.4324324
The remainder is 12 after subtracting 148 from 160.
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 14:
120 divided by 37 is 3 with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 18672.43243243
Subtracting 111 from 120 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Our division results in 18672.43243243 with a remaining 9e-09.
