81135541 ÷ 545 
We want to figure out the number of times 81135541 can be divided by 545.

Going ahead to step 1:
545 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 545

Moving on to step 2:
If we divide 81 by 545, we get 0 and a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Include the next digit (1) from the dividend after 81, then repeat: 811 / 545

Going ahead to step 3:
When dividing 811 by 545, we get 1 with a remainder of 266.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 545 from 811 and we're left with 266.
Fetch the next digit (3) from the dividend, attach it to 266 and continue: 2663 / 545

On to step 4:
The number 545 fits into 2663 4 times, leaving a remainder of 483.
Write down 4 as next digit of the result. 
Result so far: 14.0
Subtract 2180 from 2663 to get 483.
Take the next digit (5) from the dividend and append it to 483, then repeat: 4835 / 545

Let's proceed to step 5:
4835 divided by 545 is 8 with a remainder of 475.
The next digit of our result is 8. 
Result so far: 148.0
Deduct 4360 from 4835 and we're left with 475.
Take the next digit (5) from the dividend and append it to 475, then repeat: 4755 / 545

Advancing to step 6:
4755 divided by 545 is 8 with a remainder of 395.
The number 8 becomes the next digit in our result. 
Result so far: 1488.0
Subtract 4360 from 4755 to get 395.
Append the next digit (4) from the dividend to 395 and continue with: 3954 / 545

Moving on to step 7:
If we divide 3954 by 545, we get 7 and a remainder of 139.
The number 7 becomes the next digit in our result. 
Result so far: 14887.0
Deduct 3815 from 3954 and we're left with 139.
Append the next digit (1) from the dividend to 139 and continue with: 1391 / 545

Step 8:
When dividing 1391 by 545, we get 2 with a remainder of 301.
The number 2 becomes the next digit in our result. 
Result so far: 148872.0
The remainder is 301 after subtracting 1090 from 1391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Advancing to step 9:
If we divide 3010 by 545, we get 5 and a remainder of 285.
Put 5 as the next digit of the answer. 
Result so far: 148872.5
The remainder is 285 after subtracting 2725 from 3010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Step 10:
The number 545 fits into 2850 5 times, leaving a remainder of 125.
Record the quotient 5 as the next digit in the result. 
Result so far: 148872.55
If we subtract 2725 from 2850, we get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Our division results in 148872.55 with a remaining 0.125.
