Let's divide 83894989 by 642
Let's see how many times 642 fits into 83894989.

Moving on to step 1:
8 divided by 642 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 642

Moving on to step 2:
When dividing 83 by 642, we get 0 with a remainder of 83.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 83, we get 83.
Grab the next digit (8) from the dividend, add it to 83, then carry on: 838 / 642

Going ahead to step 3:
642 can be fit into 838 1 times, resulting in a remainder of 196.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 642 from 838 and we're left with 196.
Take the next digit (9) from the dividend and append it to 196, then repeat: 1969 / 642

Step 4:
When dividing 1969 by 642, we get 3 with a remainder of 43.
The next digit of our result is 3. 
Result so far: 13.0
Subtracting 1926 from 1969 leaves us with 43.
Fetch the next digit (4) from the dividend, attach it to 43 and continue: 434 / 642

Going ahead to step 5:
When dividing 434 by 642, we get 0 with a remainder of 434.
Use 0 as the next digit of our solution. 
Result so far: 130.0
Subtract 0 from 434 to get 434.
Append the next digit (9) from the dividend to 434 and continue with: 4349 / 642

Advancing to step 6:
642 goes into 4349 6 times with a remainder of 497.
Put 6 as the next digit of the answer. 
Result so far: 1306.0
The remainder is 497 after subtracting 3852 from 4349.
Fetch the next digit (8) from the dividend, attach it to 497 and continue: 4978 / 642

Let's proceed to step 7:
When dividing 4978 by 642, we get 7 with a remainder of 484.
The number 7 becomes the next digit in our result. 
Result so far: 13067.0
If we take 4494 away from 4978, we end up with 484.
Take the next digit (9) from the dividend and append it to 484, then repeat: 4849 / 642

Going ahead to step 8:
642 goes into 4849 7 times with a remainder of 355.
Record the quotient 7 as the next digit in the result. 
Result so far: 130677.0
Subtracting 4494 from 4849 leaves us with 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

On to step 9:
The number 642 fits into 3550 5 times, leaving a remainder of 340.
Write down 5 as next digit of the result. 
Result so far: 130677.5
Subtract 3210 from 3550 to get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 10:
If we divide 3400 by 642, we get 5 and a remainder of 190.
Write down 5 as next digit of the result. 
Result so far: 130677.55
Subtract 3210 from 3400 to get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

The quotient of the division is 130677.55, and the remainder is 0.19.
