649950 ÷ 37 
The aim is to understand the frequency of 37 in 649950.

Advancing to step 1:
37 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 37

Advancing to step 2:
64 divided by 37 is 1 with a remainder of 27.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 37 from 64 to get 27.
Append the next digit (9) from the dividend to 27 and continue with: 279 / 37

On to step 3:
37 goes into 279 7 times with a remainder of 20.
Write down 7 as next digit of the result. 
Result so far: 17.0
If we take 259 away from 279, we end up with 20.
Take the next digit (9) from the dividend and append it to 20, then repeat: 209 / 37

Going ahead to step 4:
When dividing 209 by 37, we get 5 with a remainder of 24.
Use 5 as the next digit of our solution. 
Result so far: 175.0
The remainder is 24 after subtracting 185 from 209.
Take the next digit (5) from the dividend and append it to 24, then repeat: 245 / 37

Step 5:
If we divide 245 by 37, we get 6 and a remainder of 23.
Write down 6 as next digit of the result. 
Result so far: 1756.0
Subtracting 222 from 245 leaves us with 23.
Append the next digit (0) from the dividend to 23 and continue with: 230 / 37

Step 6:
When dividing 230 by 37, we get 6 with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 17566.0
The remainder is 8 after subtracting 222 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 7:
If we divide 80 by 37, we get 2 and a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 17566.2
If we subtract 74 from 80, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
The number 37 fits into 60 1 times, leaving a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 17566.21
Subtract 37 from 60 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 9:
If we divide 230 by 37, we get 6 and a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 17566.216
Subtract 222 from 230 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
The number 37 fits into 80 2 times, leaving a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 17566.2162
If we take 74 away from 80, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 11:
If we divide 60 by 37, we get 1 and a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 17566.21621
If we subtract 37 from 60, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 12:
When dividing 230 by 37, we get 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 17566.216216
Subtract 222 from 230 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 13:
37 can be fit into 80 2 times, resulting in a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 17566.2162162
Subtracting 74 from 80 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 14:
60 divided by 37 is 1 with a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 17566.21621621
Subtracting 37 from 60 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

The final result is 17566.21621621 with a remainder of 2.3e-08.
