We look at the division of 36687553 by 642 
We want to figure out the number of times 36687553 can be divided by 642.

Moving on to step 1:
When dividing 3 by 642, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 642

Going ahead to step 2:
If we divide 36 by 642, we get 0 and a remainder of 36.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 36 leaves us with 36.
Take the next digit (6) from the dividend and append it to 36, then repeat: 366 / 642

Going ahead to step 3:
366 divided by 642 is 0 with a remainder of 366.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 366, we get 366.
Include the next digit (8) from the dividend after 366, then repeat: 3668 / 642

Step 4:
The number 642 fits into 3668 5 times, leaving a remainder of 458.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 3210 away from 3668, we end up with 458.
Take the next digit (7) from the dividend and append it to 458, then repeat: 4587 / 642

Advancing to step 5:
If we divide 4587 by 642, we get 7 and a remainder of 93.
Record the quotient 7 as the next digit in the result. 
Result so far: 57.0
The remainder is 93 after subtracting 4494 from 4587.
Bring next digit (5) of the dividend behind the 93 and repeat the process: 935 / 642

On to step 6:
935 divided by 642 is 1 with a remainder of 293.
Write down 1 as next digit of the result. 
Result so far: 571.0
If we take 642 away from 935, we end up with 293.
Include the next digit (5) from the dividend after 293, then repeat: 2935 / 642

Step 7:
642 goes into 2935 4 times with a remainder of 367.
Write down 4 as next digit of the result. 
Result so far: 5714.0
Subtract 2568 from 2935 to get 367.
Append the next digit (3) from the dividend to 367 and continue with: 3673 / 642

Moving on to step 8:
When dividing 3673 by 642, we get 5 with a remainder of 463.
Put 5 as the next digit of the answer. 
Result so far: 57145.0
Subtract 3210 from 3673 to get 463.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4630, and continue the process.

Advancing to step 9:
When dividing 4630 by 642, we get 7 with a remainder of 136.
The number 7 becomes the next digit in our result. 
Result so far: 57145.7
Subtracting 4494 from 4630 leaves us with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Let's proceed to step 10:
If we divide 1360 by 642, we get 2 and a remainder of 76.
The next digit of our result is 2. 
Result so far: 57145.72
Subtract 1284 from 1360 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 11:
If we divide 760 by 642, we get 1 and a remainder of 118.
Use 1 as the next digit of our solution. 
Result so far: 57145.721
Deduct 642 from 760 and we're left with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Step 12:
The number 642 fits into 1180 1 times, leaving a remainder of 538.
The next digit of our result is 1. 
Result so far: 57145.7211
Subtract 642 from 1180 to get 538.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

The quotient of the division is 57145.7211, and the remainder is 0.00538.
