520932 divided by 642 
Our goal is to divide 520932 by 642.

Moving on to step 1:
642 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 642

Step 2:
The number 642 fits into 52 0 times, leaving a remainder of 52.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 52 and we're left with 52.
Include the next digit (0) from the dividend after 52, then repeat: 520 / 642

Moving on to step 3:
642 can be fit into 520 0 times, resulting in a remainder of 520.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 520 and we're left with 520.
Include the next digit (9) from the dividend after 520, then repeat: 5209 / 642

Let's proceed to step 4:
If we divide 5209 by 642, we get 8 and a remainder of 73.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 5136 from 5209 and we're left with 73.
Append the next digit (3) from the dividend to 73 and continue with: 733 / 642

On to step 5:
The number 642 fits into 733 1 times, leaving a remainder of 91.
Write down 1 as next digit of the result. 
Result so far: 81.0
Subtracting 642 from 733 leaves us with 91.
Append the next digit (2) from the dividend to 91 and continue with: 912 / 642

Going ahead to step 6:
912 divided by 642 is 1 with a remainder of 270.
The number 1 becomes the next digit in our result. 
Result so far: 811.0
Subtract 642 from 912 to get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Moving on to step 7:
If we divide 2700 by 642, we get 4 and a remainder of 132.
Use 4 as the next digit of our solution. 
Result so far: 811.4
Deduct 2568 from 2700 and we're left with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Let's proceed to step 8:
642 can be fit into 1320 2 times, resulting in a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 811.42
If we take 1284 away from 1320, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 9:
360 divided by 642 is 0 with a remainder of 360.
The number 0 becomes the next digit in our result. 
Result so far: 811.42
If we take 0 away from 360, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

On to step 10:
If we divide 3600 by 642, we get 5 and a remainder of 390.
The number 5 becomes the next digit in our result. 
Result so far: 811.4205
Deduct 3210 from 3600 and we're left with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Step 11:
3900 divided by 642 is 6 with a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 811.42056
Deduct 3852 from 3900 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 12:
When dividing 480 by 642, we get 0 with a remainder of 480.
Put 0 as the next digit of the answer. 
Result so far: 811.42056
If we take 0 away from 480, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Advancing to step 13:
4800 divided by 642 is 7 with a remainder of 306.
The number 7 becomes the next digit in our result. 
Result so far: 811.4205607
Subtracting 4494 from 4800 leaves us with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

On to step 14:
642 can be fit into 3060 4 times, resulting in a remainder of 492.
Put 4 as the next digit of the answer. 
Result so far: 811.42056074
If we subtract 2568 from 3060, we get 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

The final result is 811.42056074 with a remainder of 4.92e-07.
