Let's divide 90100129 by 545
Let's see how many times 545 fits into 90100129.

Step 1:
When dividing 9 by 545, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 545

Advancing to step 2:
545 can be fit into 90 0 times, resulting in 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.
Take the next digit (1) from the dividend and append it to 90, then repeat: 901 / 545

Let's proceed to step 3:
When dividing 901 by 545, we get 1 with a remainder of 356.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 545 from 901 to get 356.
Include the next digit (0) from the dividend after 356, then repeat: 3560 / 545

Step 4:
When dividing 3560 by 545, we get 6 with a remainder of 290.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Deduct 3270 from 3560 and we're left with 290.
Grab the next digit (0) from the dividend, add it to 290, then carry on: 2900 / 545

Moving on to step 5:
2900 divided by 545 is 5 with a remainder of 175.
Record the quotient 5 as the next digit in the result. 
Result so far: 165.0
Subtracting 2725 from 2900 leaves us with 175.
Bring next digit (1) of the dividend behind the 175 and repeat the process: 1751 / 545

On to step 6:
545 goes into 1751 3 times with a remainder of 116.
Write down 3 as next digit of the result. 
Result so far: 1653.0
The remainder is 116 after subtracting 1635 from 1751.
Fetch the next digit (2) from the dividend, attach it to 116 and continue: 1162 / 545

Going ahead to step 7:
The number 545 fits into 1162 2 times, leaving a remainder of 72.
Use 2 as the next digit of our solution. 
Result so far: 16532.0
The remainder is 72 after subtracting 1090 from 1162.
Bring next digit (9) of the dividend behind the 72 and repeat the process: 729 / 545

Step 8:
545 can be fit into 729 1 times, resulting in a remainder of 184.
The number 1 becomes the next digit in our result. 
Result so far: 165321.0
If we subtract 545 from 729, we get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

On to step 9:
1840 divided by 545 is 3 with a remainder of 205.
The number 3 becomes the next digit in our result. 
Result so far: 165321.3
Subtracting 1635 from 1840 leaves us with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

On to step 10:
2050 divided by 545 is 3 with a remainder of 415.
The number 3 becomes the next digit in our result. 
Result so far: 165321.33
If we take 1635 away from 2050, we end up with 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

The quotient of the division is 165321.33, and the remainder is 0.415.
