We divide 870937 by 45
The aim is to understand the frequency of 45 in 870937.

Moving on to step 1:
45 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 45

Advancing to step 2:
87 divided by 45 is 1 with a remainder of 42.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 45 from 87, we get 42.
Include the next digit (0) from the dividend after 42, then repeat: 420 / 45

On to step 3:
420 divided by 45 is 9 with a remainder of 15.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
If we subtract 405 from 420, we get 15.
Bring next digit (9) of the dividend behind the 15 and repeat the process: 159 / 45

Going ahead to step 4:
When dividing 159 by 45, we get 3 with a remainder of 24.
The number 3 becomes the next digit in our result. 
Result so far: 193.0
Subtract 135 from 159 to get 24.
Grab the next digit (3) from the dividend, add it to 24, then carry on: 243 / 45

Moving on to step 5:
45 can be fit into 243 5 times, resulting in a remainder of 18.
Record the quotient 5 as the next digit in the result. 
Result so far: 1935.0
Subtracting 225 from 243 leaves us with 18.
Append the next digit (7) from the dividend to 18 and continue with: 187 / 45

On to step 6:
If we divide 187 by 45, we get 4 and a remainder of 7.
Use 4 as the next digit of our solution. 
Result so far: 19354.0
Subtracting 180 from 187 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
The number 45 fits into 70 1 times, leaving a remainder of 25.
Write down 1 as next digit of the result. 
Result so far: 19354.1
Deduct 45 from 70 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 8:
45 goes into 250 5 times with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 19354.15
The remainder is 25 after subtracting 225 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 9:
The number 45 fits into 250 5 times, leaving a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 19354.155
If we take 225 away from 250, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

After the division, we end up with 19354.155 and a remainder of 0.0025.
