We divide 640158 by 48
The aim is to understand the frequency of 48 in 640158.

Going ahead to step 1:
The number 48 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 48

Let's proceed to step 2:
48 can be fit into 64 1 times, resulting in a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 48 from 64, we get 16.
Include the next digit (0) from the dividend after 16, then repeat: 160 / 48

Going ahead to step 3:
The number 48 fits into 160 3 times, leaving a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we take 144 away from 160, we end up with 16.
Take the next digit (1) from the dividend and append it to 16, then repeat: 161 / 48

Let's proceed to step 4:
48 goes into 161 3 times with a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 133.0
If we take 144 away from 161, we end up with 17.
Include the next digit (5) from the dividend after 17, then repeat: 175 / 48

Advancing to step 5:
The number 48 fits into 175 3 times, leaving a remainder of 31.
Put 3 as the next digit of the answer. 
Result so far: 1333.0
Subtract 144 from 175 to get 31.
Include the next digit (8) from the dividend after 31, then repeat: 318 / 48

On to step 6:
When dividing 318 by 48, we get 6 with a remainder of 30.
Write down 6 as next digit of the result. 
Result so far: 13336.0
Deduct 288 from 318 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 7:
300 divided by 48 is 6 with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 13336.6
If we subtract 288 from 300, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 8:
120 divided by 48 is 2 with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 13336.62
The remainder is 24 after subtracting 96 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 9:
When dividing 240 by 48, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 13336.625
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.

Step 10:
The number 48 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 13336.625
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.

Going ahead to step 11:
If we divide 0 by 48, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 13336.625
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.

The final outcome is 13336.625, with a leftover of 0.0.
