81007355 ÷ 53 
We're looking to find how many times 53 goes into 81007355.

Advancing to step 1:
53 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
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 53

On to step 2:
When dividing 81 by 53, we get 1 with a remainder of 28.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 53 from 81 leaves us with 28.
Bring next digit (0) of the dividend behind the 28 and repeat the process: 280 / 53

Step 3:
When dividing 280 by 53, we get 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 15.0
Deduct 265 from 280 and we're left with 15.
Grab the next digit (0) from the dividend, add it to 15, then carry on: 150 / 53

Let's proceed to step 4:
If we divide 150 by 53, we get 2 and a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 152.0
The remainder is 44 after subtracting 106 from 150.
Include the next digit (7) from the dividend after 44, then repeat: 447 / 53

On to step 5:
When dividing 447 by 53, we get 8 with a remainder of 23.
The number 8 becomes the next digit in our result. 
Result so far: 1528.0
If we take 424 away from 447, we end up with 23.
Fetch the next digit (3) from the dividend, attach it to 23 and continue: 233 / 53

Let's proceed to step 6:
53 goes into 233 4 times with a remainder of 21.
The number 4 becomes the next digit in our result. 
Result so far: 15284.0
If we subtract 212 from 233, we get 21.
Fetch the next digit (5) from the dividend, attach it to 21 and continue: 215 / 53

Let's proceed to step 7:
215 divided by 53 is 4 with a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 152844.0
If we subtract 212 from 215, we get 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 53

Going ahead to step 8:
If we divide 35 by 53, we get 0 and a remainder of 35.
The number 0 becomes the next digit in our result. 
Result so far: 1528440.0
Subtracting 0 from 35 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 9:
The number 53 fits into 350 6 times, leaving a remainder of 32.
The next digit of our result is 6. 
Result so far: 1528440.6
Deduct 318 from 350 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 10:
320 divided by 53 is 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 1528440.66
Subtract 318 from 320 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The quotient of the division is 1528440.66, and the remainder is 0.002.
