We look at the division of 82050515 by 642 
Our goal is to divide 82050515 by 642.

Going ahead to step 1:
642 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 642

Advancing to step 2:
642 goes into 82 0 times with a remainder of 82.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 82 and we're left with 82.
Grab the next digit (0) from the dividend, add it to 82, then carry on: 820 / 642

Let's proceed to step 3:
If we divide 820 by 642, we get 1 and a remainder of 178.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 178 after subtracting 642 from 820.
Bring next digit (5) of the dividend behind the 178 and repeat the process: 1785 / 642

Step 4:
The number 642 fits into 1785 2 times, leaving a remainder of 501.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtracting 1284 from 1785 leaves us with 501.
Include the next digit (0) from the dividend after 501, then repeat: 5010 / 642

Going ahead to step 5:
642 goes into 5010 7 times with a remainder of 516.
Put 7 as the next digit of the answer. 
Result so far: 127.0
If we subtract 4494 from 5010, we get 516.
Append the next digit (5) from the dividend to 516 and continue with: 5165 / 642

On to step 6:
642 goes into 5165 8 times with a remainder of 29.
The next digit of our result is 8. 
Result so far: 1278.0
Subtract 5136 from 5165 to get 29.
Include the next digit (1) from the dividend after 29, then repeat: 291 / 642

Let's proceed to step 7:
When dividing 291 by 642, we get 0 with a remainder of 291.
The next digit of our result is 0. 
Result so far: 12780.0
Deduct 0 from 291 and we're left with 291.
Bring next digit (5) of the dividend behind the 291 and repeat the process: 2915 / 642

Let's proceed to step 8:
If we divide 2915 by 642, we get 4 and a remainder of 347.
The number 4 becomes the next digit in our result. 
Result so far: 127804.0
Subtracting 2568 from 2915 leaves us with 347.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3470, and continue the process.

Step 9:
If we divide 3470 by 642, we get 5 and a remainder of 260.
The next digit of our result is 5. 
Result so far: 127804.5
If we subtract 3210 from 3470, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Going ahead to step 10:
642 can be fit into 2600 4 times, resulting in a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 127804.54
If we take 2568 away from 2600, 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.

On to step 11:
642 goes into 320 0 times with a remainder of 320.
Write down 0 as next digit of the result. 
Result so far: 127804.54
If we take 0 away from 320, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 12:
642 can be fit into 3200 4 times, resulting in a remainder of 632.
The number 4 becomes the next digit in our result. 
Result so far: 127804.5404
Deduct 2568 from 3200 and we're left with 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

On to step 13:
The number 642 fits into 6320 9 times, leaving a remainder of 542.
Write down 9 as next digit of the result. 
Result so far: 127804.54049
If we take 5778 away from 6320, we end up with 542.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

Advancing to step 14:
When dividing 5420 by 642, we get 8 with a remainder of 284.
Put 8 as the next digit of the answer. 
Result so far: 127804.540498
If we take 5136 away from 5420, we end up with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Let's proceed to step 15:
If we divide 2840 by 642, we get 4 and a remainder of 272.
Record the quotient 4 as the next digit in the result. 
Result so far: 127804.5404984
Subtracting 2568 from 2840 leaves us with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Moving on to step 16:
The number 642 fits into 2720 4 times, leaving a remainder of 152.
Write down 4 as next digit of the result. 
Result so far: 127804.54049844
If we take 2568 away from 2720, we end up with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Our division results in 127804.54049844 with a remaining 1.52e-07.
