Let's divide 452946 by 37
The aim is to understand the frequency of 37 in 452946.

On to step 1:
37 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 37

Step 2:
37 goes into 45 1 times with a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 37 from 45 and we're left with 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 37

Let's proceed to step 3:
37 goes into 82 2 times with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtracting 74 from 82 leaves us with 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 37

On to step 4:
89 divided by 37 is 2 with a remainder of 15.
Put 2 as the next digit of the answer. 
Result so far: 122.0
If we take 74 away from 89, we end up with 15.
Bring next digit (4) of the dividend behind the 15 and repeat the process: 154 / 37

On to step 5:
If we divide 154 by 37, we get 4 and a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 1224.0
If we subtract 148 from 154, we get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 37

Step 6:
37 can be fit into 66 1 times, resulting in a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 12241.0
Subtract 37 from 66 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 7:
290 divided by 37 is 7 with a remainder of 31.
Record the quotient 7 as the next digit in the result. 
Result so far: 12241.7
The remainder is 31 after subtracting 259 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 8:
The number 37 fits into 310 8 times, leaving a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 12241.78
Subtract 296 from 310 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 9:
If we divide 140 by 37, we get 3 and a remainder of 29.
The number 3 becomes the next digit in our result. 
Result so far: 12241.783
Deduct 111 from 140 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 10:
290 divided by 37 is 7 with a remainder of 31.
The next digit of our result is 7. 
Result so far: 12241.7837
Subtracting 259 from 290 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 11:
If we divide 310 by 37, we get 8 and a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 12241.78378
Subtracting 296 from 310 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 12:
If we divide 140 by 37, we get 3 and a remainder of 29.
Put 3 as the next digit of the answer. 
Result so far: 12241.783783
Deduct 111 from 140 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 13:
The number 37 fits into 290 7 times, leaving a remainder of 31.
Record the quotient 7 as the next digit in the result. 
Result so far: 12241.7837837
If we take 259 away from 290, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 14:
If we divide 310 by 37, we get 8 and a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 12241.78378378
If we take 296 away from 310, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Our division results in 12241.78378378 with a remaining 1.4e-08.
