52910687 divided by 642 
We want to divide 52910687 by 642.

Let's proceed to step 1:
642 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 642

On to step 2:
52 divided by 642 is 0 with a remainder of 52.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 52, we get 52.
Grab the next digit (9) from the dividend, add it to 52, then carry on: 529 / 642

Going ahead to step 3:
642 goes into 529 0 times with a remainder of 529.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 529 and we're left with 529.
Grab the next digit (1) from the dividend, add it to 529, then carry on: 5291 / 642

Going ahead to step 4:
5291 divided by 642 is 8 with a remainder of 155.
The next digit of our result is 8. 
Result so far: 8.0
Subtracting 5136 from 5291 leaves us with 155.
Append the next digit (0) from the dividend to 155 and continue with: 1550 / 642

Advancing to step 5:
642 goes into 1550 2 times with a remainder of 266.
Put 2 as the next digit of the answer. 
Result so far: 82.0
Subtract 1284 from 1550 to get 266.
Append the next digit (6) from the dividend to 266 and continue with: 2666 / 642

Going ahead to step 6:
If we divide 2666 by 642, we get 4 and a remainder of 98.
Use 4 as the next digit of our solution. 
Result so far: 824.0
The remainder is 98 after subtracting 2568 from 2666.
Grab the next digit (8) from the dividend, add it to 98, then carry on: 988 / 642

Going ahead to step 7:
If we divide 988 by 642, we get 1 and a remainder of 346.
Put 1 as the next digit of the answer. 
Result so far: 8241.0
The remainder is 346 after subtracting 642 from 988.
Include the next digit (7) from the dividend after 346, then repeat: 3467 / 642

Let's proceed to step 8:
When dividing 3467 by 642, we get 5 with a remainder of 257.
The number 5 becomes the next digit in our result. 
Result so far: 82415.0
Subtract 3210 from 3467 to get 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

Advancing to step 9:
If we divide 2570 by 642, we get 4 and a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 82415.4
Subtract 2568 from 2570 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 10:
When dividing 20 by 642, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 82415.4
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 11:
642 goes into 200 0 times with a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 82415.4
Subtracting 0 from 200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final result is 82415.4 with a remainder of 0.02.
