Let's divide 90626454 by 642
We're looking to find how many times 642 goes into 90626454.

Going ahead to step 1:
When dividing 9 by 642, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 642

On to step 2:
When dividing 90 by 642, we get 0 with a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 90 after subtracting 0 from 90.
Take the next digit (6) from the dividend and append it to 90, then repeat: 906 / 642

Advancing to step 3:
When dividing 906 by 642, we get 1 with a remainder of 264.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 642 from 906 to get 264.
Append the next digit (2) from the dividend to 264 and continue with: 2642 / 642

Advancing to step 4:
642 can be fit into 2642 4 times, resulting in a remainder of 74.
Put 4 as the next digit of the answer. 
Result so far: 14.0
The remainder is 74 after subtracting 2568 from 2642.
Take the next digit (6) from the dividend and append it to 74, then repeat: 746 / 642

Advancing to step 5:
642 can be fit into 746 1 times, resulting in a remainder of 104.
Put 1 as the next digit of the answer. 
Result so far: 141.0
Deduct 642 from 746 and we're left with 104.
Grab the next digit (4) from the dividend, add it to 104, then carry on: 1044 / 642

Step 6:
1044 divided by 642 is 1 with a remainder of 402.
The number 1 becomes the next digit in our result. 
Result so far: 1411.0
If we subtract 642 from 1044, we get 402.
Take the next digit (5) from the dividend and append it to 402, then repeat: 4025 / 642

Let's proceed to step 7:
The number 642 fits into 4025 6 times, leaving a remainder of 173.
Record the quotient 6 as the next digit in the result. 
Result so far: 14116.0
If we take 3852 away from 4025, we end up with 173.
Grab the next digit (4) from the dividend, add it to 173, then carry on: 1734 / 642

On to step 8:
642 can be fit into 1734 2 times, resulting in a remainder of 450.
The next digit of our result is 2. 
Result so far: 141162.0
Subtracting 1284 from 1734 leaves us with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Advancing to step 9:
642 can be fit into 4500 7 times, resulting in a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 141162.7
The remainder is 6 after subtracting 4494 from 4500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 10:
The number 642 fits into 60 0 times, leaving a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 141162.7
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 11:
The number 642 fits into 600 0 times, leaving a remainder of 600.
Use 0 as the next digit of our solution. 
Result so far: 141162.7
If we take 0 away from 600, we end up with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

The final outcome is 141162.7, with a leftover of 0.06.
