645794 ÷ 48 
We want to figure out the number of times 645794 can be divided by 48.

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
The remainder is 6 after subtracting 0 from 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 48

Going ahead to step 2:
48 goes into 64 1 times with a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 48 from 64 to get 16.
Grab the next digit (5) from the dividend, add it to 16, then carry on: 165 / 48

On to step 3:
48 can be fit into 165 3 times, resulting in a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtract 144 from 165 to get 21.
Take the next digit (7) from the dividend and append it to 21, then repeat: 217 / 48

On to step 4:
If we divide 217 by 48, we get 4 and a remainder of 25.
Put 4 as the next digit of the answer. 
Result so far: 134.0
The remainder is 25 after subtracting 192 from 217.
Append the next digit (9) from the dividend to 25 and continue with: 259 / 48

On to step 5:
The number 48 fits into 259 5 times, leaving a remainder of 19.
Use 5 as the next digit of our solution. 
Result so far: 1345.0
The remainder is 19 after subtracting 240 from 259.
Bring next digit (4) of the dividend behind the 19 and repeat the process: 194 / 48

Step 6:
If we divide 194 by 48, we get 4 and a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 13454.0
If we take 192 away from 194, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
The number 48 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 13454.0
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
The number 48 fits into 200 4 times, leaving a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 13454.04
Deduct 192 from 200 and we're left with 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 9:
48 can be fit into 80 1 times, resulting in a remainder of 32.
The next digit of our result is 1. 
Result so far: 13454.041
If we take 48 away from 80, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 10:
48 goes into 320 6 times with a remainder of 32.
The next digit of our result is 6. 
Result so far: 13454.0416
If we subtract 288 from 320, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 11:
320 divided by 48 is 6 with a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 13454.04166
If we take 288 away from 320, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Our division results in 13454.04166 with a remaining 3.2e-05.
