We're dividing 90773545 by 213 
Our goal is to divide 90773545 by 213.

Let's proceed to step 1:
When dividing 9 by 213, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 213

Moving on to step 2:
If we divide 90 by 213, we get 0 and a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Fetch the next digit (7) from the dividend, attach it to 90 and continue: 907 / 213

Moving on to step 3:
If we divide 907 by 213, we get 4 and a remainder of 55.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 55 after subtracting 852 from 907.
Append the next digit (7) from the dividend to 55 and continue with: 557 / 213

Moving on to step 4:
When dividing 557 by 213, we get 2 with a remainder of 131.
Write down 2 as next digit of the result. 
Result so far: 42.0
Subtract 426 from 557 to get 131.
Include the next digit (3) from the dividend after 131, then repeat: 1313 / 213

Let's proceed to step 5:
1313 divided by 213 is 6 with a remainder of 35.
Put 6 as the next digit of the answer. 
Result so far: 426.0
The remainder is 35 after subtracting 1278 from 1313.
Fetch the next digit (5) from the dividend, attach it to 35 and continue: 355 / 213

Let's proceed to step 6:
213 goes into 355 1 times with a remainder of 142.
Use 1 as the next digit of our solution. 
Result so far: 4261.0
Deduct 213 from 355 and we're left with 142.
Include the next digit (4) from the dividend after 142, then repeat: 1424 / 213

Step 7:
213 goes into 1424 6 times with a remainder of 146.
The next digit of our result is 6. 
Result so far: 42616.0
Subtracting 1278 from 1424 leaves us with 146.
Take the next digit (5) from the dividend and append it to 146, then repeat: 1465 / 213

Moving on to step 8:
The number 213 fits into 1465 6 times, leaving a remainder of 187.
Write down 6 as next digit of the result. 
Result so far: 426166.0
If we take 1278 away from 1465, we end up with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Let's proceed to step 9:
213 can be fit into 1870 8 times, resulting in a remainder of 166.
The number 8 becomes the next digit in our result. 
Result so far: 426166.8
Subtracting 1704 from 1870 leaves us with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

On to step 10:
When dividing 1660 by 213, we get 7 with a remainder of 169.
Use 7 as the next digit of our solution. 
Result so far: 426166.87
The remainder is 169 after subtracting 1491 from 1660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Step 11:
If we divide 1690 by 213, we get 7 and a remainder of 199.
The next digit of our result is 7. 
Result so far: 426166.877
Subtracting 1491 from 1690 leaves us with 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

The final result is 426166.877 with a remainder of 0.0199.
