We look at the division of 90897631 by 545 
We're looking to find how many times 545 goes into 90897631.

Let's proceed to step 1:
9 divided by 545 is 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 545

On to step 2:
The number 545 fits into 90 0 times, leaving a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 90, we get 90.
Include the next digit (8) from the dividend after 90, then repeat: 908 / 545

Advancing to step 3:
If we divide 908 by 545, we get 1 and a remainder of 363.
The next digit of our result is 1. 
Result so far: 1.0
If we take 545 away from 908, we end up with 363.
Bring next digit (9) of the dividend behind the 363 and repeat the process: 3639 / 545

Going ahead to step 4:
When dividing 3639 by 545, we get 6 with a remainder of 369.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
If we subtract 3270 from 3639, we get 369.
Bring next digit (7) of the dividend behind the 369 and repeat the process: 3697 / 545

Step 5:
545 goes into 3697 6 times with a remainder of 427.
The next digit of our result is 6. 
Result so far: 166.0
Deduct 3270 from 3697 and we're left with 427.
Include the next digit (6) from the dividend after 427, then repeat: 4276 / 545

Moving on to step 6:
545 goes into 4276 7 times with a remainder of 461.
Use 7 as the next digit of our solution. 
Result so far: 1667.0
Subtract 3815 from 4276 to get 461.
Include the next digit (3) from the dividend after 461, then repeat: 4613 / 545

Let's proceed to step 7:
4613 divided by 545 is 8 with a remainder of 253.
Write down 8 as next digit of the result. 
Result so far: 16678.0
Subtracting 4360 from 4613 leaves us with 253.
Bring next digit (1) of the dividend behind the 253 and repeat the process: 2531 / 545

Going ahead to step 8:
When dividing 2531 by 545, we get 4 with a remainder of 351.
Use 4 as the next digit of our solution. 
Result so far: 166784.0
Subtract 2180 from 2531 to get 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Going ahead to step 9:
3510 divided by 545 is 6 with a remainder of 240.
The number 6 becomes the next digit in our result. 
Result so far: 166784.6
Subtracting 3270 from 3510 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 10:
When dividing 2400 by 545, we get 4 with a remainder of 220.
The number 4 becomes the next digit in our result. 
Result so far: 166784.64
If we subtract 2180 from 2400, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Step 11:
If we divide 2200 by 545, we get 4 and a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 166784.644
Deduct 2180 from 2200 and we're left 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.

The quotient of the division is 166784.644, and the remainder is 0.002.
