Let's divide 90647147 by 642
We want to figure out the number of times 90647147 can be divided by 642.

Let's proceed to step 1:
642 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 642

Advancing to step 2:
642 can be fit into 90 0 times, resulting in a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 90 leaves us with 90.
Fetch the next digit (6) from the dividend, attach it to 90 and continue: 906 / 642

Let's proceed to step 3:
642 can be fit into 906 1 times, resulting in a remainder of 264.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 642 from 906 and we're left with 264.
Bring next digit (4) of the dividend behind the 264 and repeat the process: 2644 / 642

Step 4:
642 can be fit into 2644 4 times, resulting in a remainder of 76.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtract 2568 from 2644 to get 76.
Grab the next digit (7) from the dividend, add it to 76, then carry on: 767 / 642

Advancing to step 5:
767 divided by 642 is 1 with a remainder of 125.
The number 1 becomes the next digit in our result. 
Result so far: 141.0
Deduct 642 from 767 and we're left with 125.
Append the next digit (1) from the dividend to 125 and continue with: 1251 / 642

Going ahead to step 6:
642 goes into 1251 1 times with a remainder of 609.
The number 1 becomes the next digit in our result. 
Result so far: 1411.0
If we take 642 away from 1251, we end up with 609.
Append the next digit (4) from the dividend to 609 and continue with: 6094 / 642

Moving on to step 7:
When dividing 6094 by 642, we get 9 with a remainder of 316.
The next digit of our result is 9. 
Result so far: 14119.0
If we subtract 5778 from 6094, we get 316.
Include the next digit (7) from the dividend after 316, then repeat: 3167 / 642

Let's proceed to step 8:
642 goes into 3167 4 times with a remainder of 599.
The next digit of our result is 4. 
Result so far: 141194.0
The remainder is 599 after subtracting 2568 from 3167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5990, and continue the process.

Moving on to step 9:
If we divide 5990 by 642, we get 9 and a remainder of 212.
Put 9 as the next digit of the answer. 
Result so far: 141194.9
Subtract 5778 from 5990 to get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Going ahead to step 10:
The number 642 fits into 2120 3 times, leaving a remainder of 194.
Write down 3 as next digit of the result. 
Result so far: 141194.93
Subtract 1926 from 2120 to get 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Going ahead to step 11:
The number 642 fits into 1940 3 times, leaving a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 141194.933
The remainder is 14 after subtracting 1926 from 1940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final outcome is 141194.933, with a leftover of 0.0014.
