We're dividing 64151670 by 90 
Let's see how many times 90 fits into 64151670.

Step 1:
90 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 90

Let's proceed to step 2:
If we divide 64 by 90, we get 0 and 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.
Grab the next digit (1) from the dividend, add it to 64, then carry on: 641 / 90

Moving on to step 3:
641 divided by 90 is 7 with a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 7.0
The remainder is 11 after subtracting 630 from 641.
Take the next digit (5) from the dividend and append it to 11, then repeat: 115 / 90

Let's proceed to step 4:
90 goes into 115 1 times with a remainder of 25.
Record the quotient 1 as the next digit in the result. 
Result so far: 71.0
The remainder is 25 after subtracting 90 from 115.
Take the next digit (1) from the dividend and append it to 25, then repeat: 251 / 90

On to step 5:
If we divide 251 by 90, we get 2 and a remainder of 71.
The number 2 becomes the next digit in our result. 
Result so far: 712.0
If we take 180 away from 251, we end up with 71.
Grab the next digit (6) from the dividend, add it to 71, then carry on: 716 / 90

Moving on to step 6:
When dividing 716 by 90, we get 7 with a remainder of 86.
Record the quotient 7 as the next digit in the result. 
Result so far: 7127.0
Subtract 630 from 716 to get 86.
Fetch the next digit (7) from the dividend, attach it to 86 and continue: 867 / 90

Advancing to step 7:
When dividing 867 by 90, we get 9 with a remainder of 57.
The number 9 becomes the next digit in our result. 
Result so far: 71279.0
Subtracting 810 from 867 leaves us with 57.
Bring next digit (0) of the dividend behind the 57 and repeat the process: 570 / 90

On to step 8:
90 goes into 570 6 times with a remainder of 30.
Use 6 as the next digit of our solution. 
Result so far: 712796.0
The remainder is 30 after subtracting 540 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 9:
90 goes into 300 3 times with a remainder of 30.
Use 3 as the next digit of our solution. 
Result so far: 712796.3
Subtracting 270 from 300 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 10:
The number 90 fits into 300 3 times, leaving a remainder of 30.
Record the quotient 3 as the next digit in the result. 
Result so far: 712796.33
The remainder is 30 after subtracting 270 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The quotient of the division is 712796.33, and the remainder is 0.03.
