We divide 642191 by 48
We want to figure out the number of times 642191 can be divided by 48.

Step 1:
48 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 48

Going ahead to step 2:
The number 48 fits into 64 1 times, leaving a remainder of 16.
The next digit of our result is 1. 
Result so far: 1.0
If we take 48 away from 64, we end up with 16.
Append the next digit (2) from the dividend to 16 and continue with: 162 / 48

Step 3:
162 divided by 48 is 3 with a remainder of 18.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtracting 144 from 162 leaves us with 18.
Append the next digit (1) from the dividend to 18 and continue with: 181 / 48

Going ahead to step 4:
The number 48 fits into 181 3 times, leaving a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 133.0
Deduct 144 from 181 and we're left with 37.
Bring next digit (9) of the dividend behind the 37 and repeat the process: 379 / 48

Let's proceed to step 5:
The number 48 fits into 379 7 times, leaving a remainder of 43.
The number 7 becomes the next digit in our result. 
Result so far: 1337.0
Subtracting 336 from 379 leaves us with 43.
Grab the next digit (1) from the dividend, add it to 43, then carry on: 431 / 48

Step 6:
48 can be fit into 431 8 times, resulting in a remainder of 47.
Use 8 as the next digit of our solution. 
Result so far: 13378.0
Deduct 384 from 431 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 7:
48 can be fit into 470 9 times, resulting in a remainder of 38.
Use 9 as the next digit of our solution. 
Result so far: 13378.9
Subtracting 432 from 470 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 8:
If we divide 380 by 48, we get 7 and a remainder of 44.
Put 7 as the next digit of the answer. 
Result so far: 13378.97
Subtracting 336 from 380 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 9:
If we divide 440 by 48, we get 9 and a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 13378.979
If we take 432 away from 440, we end up 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.

On to step 10:
48 goes into 80 1 times with a remainder of 32.
The next digit of our result is 1. 
Result so far: 13378.9791
If we subtract 48 from 80, 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.

Advancing to step 11:
When dividing 320 by 48, we get 6 with a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 13378.97916
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.

Step 12:
48 can be fit into 320 6 times, resulting in a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 13378.979166
Deduct 288 from 320 and we're left 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 13378.979166 with a remaining 3.2e-06.
