64050698 ÷ 90 
Our goal is to divide 64050698 by 90.

Advancing to step 1:
90 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 90

Step 2:
90 can be fit into 64 0 times, resulting in a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Append the next digit (0) from the dividend to 64 and continue with: 640 / 90

Going ahead to step 3:
When dividing 640 by 90, we get 7 with a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 630 from 640 leaves us with 10.
Take the next digit (5) from the dividend and append it to 10, then repeat: 105 / 90

Going ahead to step 4:
90 goes into 105 1 times with a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 71.0
If we subtract 90 from 105, we get 15.
Grab the next digit (0) from the dividend, add it to 15, then carry on: 150 / 90

Moving on to step 5:
150 divided by 90 is 1 with a remainder of 60.
Write down 1 as next digit of the result. 
Result so far: 711.0
If we subtract 90 from 150, we get 60.
Fetch the next digit (6) from the dividend, attach it to 60 and continue: 606 / 90

Let's proceed to step 6:
If we divide 606 by 90, we get 6 and a remainder of 66.
Record the quotient 6 as the next digit in the result. 
Result so far: 7116.0
Subtracting 540 from 606 leaves us with 66.
Include the next digit (9) from the dividend after 66, then repeat: 669 / 90

Let's proceed to step 7:
When dividing 669 by 90, we get 7 with a remainder of 39.
The number 7 becomes the next digit in our result. 
Result so far: 71167.0
If we subtract 630 from 669, we get 39.
Append the next digit (8) from the dividend to 39 and continue with: 398 / 90

Moving on to step 8:
The number 90 fits into 398 4 times, leaving a remainder of 38.
The next digit of our result is 4. 
Result so far: 711674.0
Subtracting 360 from 398 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 9:
90 goes into 380 4 times with a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 711674.4
Subtracting 360 from 380 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 10:
200 divided by 90 is 2 with a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 711674.42
If we take 180 away from 200, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 11:
200 divided by 90 is 2 with a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 711674.422
If we subtract 180 from 200, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 711674.422 with a remainder of 0.002.
