We're dividing 64176483 by 90 
Our goal is to divide 64176483 by 90.

Moving on 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
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 90

On to step 2:
When dividing 64 by 90, we get 0 with a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Take the next digit (1) from the dividend and append it to 64, then repeat: 641 / 90

Step 3:
641 divided by 90 is 7 with a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 11 after subtracting 630 from 641.
Append the next digit (7) from the dividend to 11 and continue with: 117 / 90

On to step 4:
90 can be fit into 117 1 times, resulting in a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 71.0
Deduct 90 from 117 and we're left with 27.
Fetch the next digit (6) from the dividend, attach it to 27 and continue: 276 / 90

Step 5:
90 goes into 276 3 times with a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 713.0
Deduct 270 from 276 and we're left with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 90

On to step 6:
When dividing 64 by 90, we get 0 with a remainder of 64.
The next digit of our result is 0. 
Result so far: 7130.0
If we subtract 0 from 64, we get 64.
Bring next digit (8) of the dividend behind the 64 and repeat the process: 648 / 90

Advancing to step 7:
If we divide 648 by 90, we get 7 and a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 71307.0
If we subtract 630 from 648, we get 18.
Fetch the next digit (3) from the dividend, attach it to 18 and continue: 183 / 90

On to step 8:
The number 90 fits into 183 2 times, leaving a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 713072.0
Subtract 180 from 183 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 9:
The number 90 fits into 30 0 times, leaving a remainder of 30.
The next digit of our result is 0. 
Result so far: 713072.0
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 10:
If we divide 300 by 90, we get 3 and a remainder of 30.
The number 3 becomes the next digit in our result. 
Result so far: 713072.03
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.

Moving on to step 11:
90 can be fit into 300 3 times, resulting in a remainder of 30.
Write down 3 as next digit of the result. 
Result so far: 713072.033
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 final outcome is 713072.033, with a leftover of 0.003.
