646662 ÷ 48 
The aim is to understand the frequency of 48 in 646662.

On to step 1:
If we divide 6 by 48, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 48

Advancing to step 2:
If we divide 64 by 48, we get 1 and a remainder of 16.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 48 from 64 to get 16.
Append the next digit (6) from the dividend to 16 and continue with: 166 / 48

Let's proceed to step 3:
48 goes into 166 3 times with a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtract 144 from 166 to get 22.
Append the next digit (6) from the dividend to 22 and continue with: 226 / 48

Step 4:
226 divided by 48 is 4 with a remainder of 34.
The number 4 becomes the next digit in our result. 
Result so far: 134.0
If we take 192 away from 226, we end up with 34.
Bring next digit (6) of the dividend behind the 34 and repeat the process: 346 / 48

On to step 5:
If we divide 346 by 48, we get 7 and a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 1347.0
Subtracting 336 from 346 leaves us with 10.
Include the next digit (2) from the dividend after 10, then repeat: 102 / 48

Advancing to step 6:
When dividing 102 by 48, we get 2 with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 13472.0
Deduct 96 from 102 and we're left 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 7:
When dividing 60 by 48, we get 1 with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 13472.1
Subtracting 48 from 60 leaves us 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.

On to step 8:
When dividing 120 by 48, we get 2 with a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 13472.12
If we take 96 away from 120, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 9:
If we divide 240 by 48, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 13472.125
If we take 240 away from 240, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
If we divide 0 by 48, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 13472.125
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
If we divide 0 by 48, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 13472.125
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 13472.125, with a leftover of 0.0.
