We're dividing 691885 by 37 
The aim is to understand the frequency of 37 in 691885.

Advancing to step 1:
The number 37 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 37

On to step 2:
If we divide 69 by 37, we get 1 and a remainder of 32.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 37 away from 69, we end up with 32.
Fetch the next digit (1) from the dividend, attach it to 32 and continue: 321 / 37

On to step 3:
If we divide 321 by 37, we get 8 and a remainder of 25.
The next digit of our result is 8. 
Result so far: 18.0
Subtracting 296 from 321 leaves us with 25.
Fetch the next digit (8) from the dividend, attach it to 25 and continue: 258 / 37

Going ahead to step 4:
37 can be fit into 258 6 times, resulting in a remainder of 36.
The next digit of our result is 6. 
Result so far: 186.0
Subtract 222 from 258 to get 36.
Bring next digit (8) of the dividend behind the 36 and repeat the process: 368 / 37

On to step 5:
The number 37 fits into 368 9 times, leaving a remainder of 35.
The number 9 becomes the next digit in our result. 
Result so far: 1869.0
The remainder is 35 after subtracting 333 from 368.
Bring next digit (5) of the dividend behind the 35 and repeat the process: 355 / 37

Going ahead to step 6:
355 divided by 37 is 9 with a remainder of 22.
The number 9 becomes the next digit in our result. 
Result so far: 18699.0
If we take 333 away from 355, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 7:
When dividing 220 by 37, we get 5 with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 18699.5
Deduct 185 from 220 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 8:
37 goes into 350 9 times with a remainder of 17.
The number 9 becomes the next digit in our result. 
Result so far: 18699.59
Subtracting 333 from 350 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 9:
37 can be fit into 170 4 times, resulting in a remainder of 22.
Use 4 as the next digit of our solution. 
Result so far: 18699.594
If we take 148 away from 170, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 10:
37 can be fit into 220 5 times, resulting in a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 18699.5945
Deduct 185 from 220 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 11:
37 goes into 350 9 times with a remainder of 17.
Use 9 as the next digit of our solution. 
Result so far: 18699.59459
Deduct 333 from 350 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 12:
The number 37 fits into 170 4 times, leaving a remainder of 22.
The next digit of our result is 4. 
Result so far: 18699.594594
Subtract 148 from 170 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 13:
220 divided by 37 is 5 with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 18699.5945945
Subtracting 185 from 220 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 14:
When dividing 350 by 37, we get 9 with a remainder of 17.
The next digit of our result is 9. 
Result so far: 18699.59459459
Subtract 333 from 350 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

After the division, we end up with 18699.59459459 and a remainder of 1.7e-08.
