We look at the division of 73472260 by 642 
We want to figure out the number of times 73472260 can be divided by 642.

Going ahead to step 1:
If we divide 7 by 642, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 642

On to step 2:
The number 642 fits into 73 0 times, leaving a remainder of 73.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 73 and we're left with 73.
Include the next digit (4) from the dividend after 73, then repeat: 734 / 642

On to step 3:
If we divide 734 by 642, we get 1 and a remainder of 92.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 642 from 734, we get 92.
Append the next digit (7) from the dividend to 92 and continue with: 927 / 642

On to step 4:
If we divide 927 by 642, we get 1 and a remainder of 285.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we take 642 away from 927, we end up with 285.
Take the next digit (2) from the dividend and append it to 285, then repeat: 2852 / 642

Let's proceed to step 5:
When dividing 2852 by 642, we get 4 with a remainder of 284.
Write down 4 as next digit of the result. 
Result so far: 114.0
Subtract 2568 from 2852 to get 284.
Append the next digit (2) from the dividend to 284 and continue with: 2842 / 642

Going ahead to step 6:
The number 642 fits into 2842 4 times, leaving a remainder of 274.
The number 4 becomes the next digit in our result. 
Result so far: 1144.0
Subtract 2568 from 2842 to get 274.
Append the next digit (6) from the dividend to 274 and continue with: 2746 / 642

On to step 7:
If we divide 2746 by 642, we get 4 and a remainder of 178.
Write down 4 as next digit of the result. 
Result so far: 11444.0
If we take 2568 away from 2746, we end up with 178.
Take the next digit (0) from the dividend and append it to 178, then repeat: 1780 / 642

Step 8:
If we divide 1780 by 642, we get 2 and a remainder of 496.
Put 2 as the next digit of the answer. 
Result so far: 114442.0
Subtract 1284 from 1780 to get 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Step 9:
The number 642 fits into 4960 7 times, leaving a remainder of 466.
Put 7 as the next digit of the answer. 
Result so far: 114442.7
The remainder is 466 after subtracting 4494 from 4960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

Going ahead to step 10:
642 can be fit into 4660 7 times, resulting in a remainder of 166.
The next digit of our result is 7. 
Result so far: 114442.77
Subtract 4494 from 4660 to get 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

The final outcome is 114442.77, with a leftover of 0.166.
