Let's divide 90509402 by 677
We want to figure out the number of times 90509402 can be divided by 677.

Let's proceed to step 1:
If we divide 9 by 677, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 677

Step 2:
When dividing 90 by 677, we get 0 with a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 90, we end up with 90.
Fetch the next digit (5) from the dividend, attach it to 90 and continue: 905 / 677

Advancing to step 3:
677 can be fit into 905 1 times, resulting in a remainder of 228.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 677 from 905 to get 228.
Grab the next digit (0) from the dividend, add it to 228, then carry on: 2280 / 677

Let's proceed to step 4:
If we divide 2280 by 677, we get 3 and a remainder of 249.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtracting 2031 from 2280 leaves us with 249.
Append the next digit (9) from the dividend to 249 and continue with: 2499 / 677

Let's proceed to step 5:
If we divide 2499 by 677, we get 3 and a remainder of 468.
The next digit of our result is 3. 
Result so far: 133.0
Subtract 2031 from 2499 to get 468.
Grab the next digit (4) from the dividend, add it to 468, then carry on: 4684 / 677

Advancing to step 6:
If we divide 4684 by 677, we get 6 and a remainder of 622.
Write down 6 as next digit of the result. 
Result so far: 1336.0
Deduct 4062 from 4684 and we're left with 622.
Take the next digit (0) from the dividend and append it to 622, then repeat: 6220 / 677

Advancing to step 7:
677 can be fit into 6220 9 times, resulting in a remainder of 127.
Record the quotient 9 as the next digit in the result. 
Result so far: 13369.0
The remainder is 127 after subtracting 6093 from 6220.
Take the next digit (2) from the dividend and append it to 127, then repeat: 1272 / 677

Going ahead to step 8:
677 goes into 1272 1 times with a remainder of 595.
Write down 1 as next digit of the result. 
Result so far: 133691.0
If we subtract 677 from 1272, we get 595.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5950, and continue the process.

Going ahead to step 9:
When dividing 5950 by 677, we get 8 with a remainder of 534.
The number 8 becomes the next digit in our result. 
Result so far: 133691.8
Subtract 5416 from 5950 to get 534.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

Advancing to step 10:
677 goes into 5340 7 times with a remainder of 601.
Record the quotient 7 as the next digit in the result. 
Result so far: 133691.87
If we take 4739 away from 5340, we end up with 601.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6010, and continue the process.

On to step 11:
677 can be fit into 6010 8 times, resulting in a remainder of 594.
The next digit of our result is 8. 
Result so far: 133691.878
If we subtract 5416 from 6010, we get 594.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5940, and continue the process.

Step 12:
The number 677 fits into 5940 8 times, leaving a remainder of 524.
Use 8 as the next digit of our solution. 
Result so far: 133691.8788
If we subtract 5416 from 5940, we get 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

The final result is 133691.8788 with a remainder of 0.00524.
