Let's divide 52044397 by 642
Let's see how many times 642 fits into 52044397.

Moving on to step 1:
The number 642 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 642

On to step 2:
The number 642 fits into 52 0 times, leaving a remainder of 52.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 52, we get 52.
Grab the next digit (0) from the dividend, add it to 52, then carry on: 520 / 642

Going ahead to step 3:
642 can be fit into 520 0 times, resulting in a remainder of 520.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 520, we end up with 520.
Include the next digit (4) from the dividend after 520, then repeat: 5204 / 642

On to step 4:
5204 divided by 642 is 8 with a remainder of 68.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 5136 from 5204 leaves us with 68.
Grab the next digit (4) from the dividend, add it to 68, then carry on: 684 / 642

Advancing to step 5:
When dividing 684 by 642, we get 1 with a remainder of 42.
The next digit of our result is 1. 
Result so far: 81.0
Subtract 642 from 684 to get 42.
Include the next digit (3) from the dividend after 42, then repeat: 423 / 642

Step 6:
When dividing 423 by 642, we get 0 with a remainder of 423.
Use 0 as the next digit of our solution. 
Result so far: 810.0
If we subtract 0 from 423, we get 423.
Include the next digit (9) from the dividend after 423, then repeat: 4239 / 642

Let's proceed to step 7:
4239 divided by 642 is 6 with a remainder of 387.
Write down 6 as next digit of the result. 
Result so far: 8106.0
The remainder is 387 after subtracting 3852 from 4239.
Include the next digit (7) from the dividend after 387, then repeat: 3877 / 642

Moving on to step 8:
642 goes into 3877 6 times with a remainder of 25.
Put 6 as the next digit of the answer. 
Result so far: 81066.0
If we subtract 3852 from 3877, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 9:
The number 642 fits into 250 0 times, leaving a remainder of 250.
Put 0 as the next digit of the answer. 
Result so far: 81066.0
Subtracting 0 from 250 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Advancing to step 10:
If we divide 2500 by 642, we get 3 and a remainder of 574.
Record the quotient 3 as the next digit in the result. 
Result so far: 81066.03
Subtract 1926 from 2500 to get 574.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5740, and continue the process.

Moving on to step 11:
The number 642 fits into 5740 8 times, leaving a remainder of 604.
Put 8 as the next digit of the answer. 
Result so far: 81066.038
Subtracting 5136 from 5740 leaves us with 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

On to step 12:
6040 divided by 642 is 9 with a remainder of 262.
Use 9 as the next digit of our solution. 
Result so far: 81066.0389
If we take 5778 away from 6040, we end up with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Going ahead to step 13:
If we divide 2620 by 642, we get 4 and a remainder of 52.
The next digit of our result is 4. 
Result so far: 81066.03894
Deduct 2568 from 2620 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 14:
520 divided by 642 is 0 with a remainder of 520.
Put 0 as the next digit of the answer. 
Result so far: 81066.03894
If we subtract 0 from 520, we get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Moving on to step 15:
The number 642 fits into 5200 8 times, leaving a remainder of 64.
Put 8 as the next digit of the answer. 
Result so far: 81066.0389408
Subtracting 5136 from 5200 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 16:
When dividing 640 by 642, we get 0 with a remainder of 640.
Record the quotient 0 as the next digit in the result. 
Result so far: 81066.0389408
Subtracting 0 from 640 leaves us with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

The quotient of the division is 81066.0389408, and the remainder is 6.4e-07.
