81313414 divided by 535 
We want to figure out the number of times 81313414 can be divided by 535.

On to step 1:
When dividing 8 by 535, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 535

Going ahead to step 2:
535 can be fit into 81 0 times, resulting in a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Fetch the next digit (3) from the dividend, attach it to 81 and continue: 813 / 535

Let's proceed to step 3:
535 can be fit into 813 1 times, resulting in a remainder of 278.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 278 after subtracting 535 from 813.
Include the next digit (1) from the dividend after 278, then repeat: 2781 / 535

On to step 4:
535 can be fit into 2781 5 times, resulting in a remainder of 106.
The next digit of our result is 5. 
Result so far: 15.0
Subtracting 2675 from 2781 leaves us with 106.
Fetch the next digit (3) from the dividend, attach it to 106 and continue: 1063 / 535

Advancing to step 5:
535 goes into 1063 1 times with a remainder of 528.
Record the quotient 1 as the next digit in the result. 
Result so far: 151.0
The remainder is 528 after subtracting 535 from 1063.
Take the next digit (4) from the dividend and append it to 528, then repeat: 5284 / 535

On to step 6:
535 goes into 5284 9 times with a remainder of 469.
The number 9 becomes the next digit in our result. 
Result so far: 1519.0
If we subtract 4815 from 5284, we get 469.
Bring next digit (1) of the dividend behind the 469 and repeat the process: 4691 / 535

On to step 7:
The number 535 fits into 4691 8 times, leaving a remainder of 411.
Put 8 as the next digit of the answer. 
Result so far: 15198.0
Subtracting 4280 from 4691 leaves us with 411.
Bring next digit (4) of the dividend behind the 411 and repeat the process: 4114 / 535

Let's proceed to step 8:
535 can be fit into 4114 7 times, resulting in a remainder of 369.
The next digit of our result is 7. 
Result so far: 151987.0
Subtracting 3745 from 4114 leaves us with 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

Advancing to step 9:
535 can be fit into 3690 6 times, resulting in a remainder of 480.
Put 6 as the next digit of the answer. 
Result so far: 151987.6
If we subtract 3210 from 3690, we get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Going ahead to step 10:
535 goes into 4800 8 times with a remainder of 520.
Use 8 as the next digit of our solution. 
Result so far: 151987.68
If we take 4280 away from 4800, we end up with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Advancing to step 11:
The number 535 fits into 5200 9 times, leaving a remainder of 385.
The number 9 becomes the next digit in our result. 
Result so far: 151987.689
Subtracting 4815 from 5200 leaves us with 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Going ahead to step 12:
If we divide 3850 by 535, we get 7 and a remainder of 105.
The next digit of our result is 7. 
Result so far: 151987.6897
If we take 3745 away from 3850, we end up with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Step 13:
535 can be fit into 1050 1 times, resulting in a remainder of 515.
The next digit of our result is 1. 
Result so far: 151987.68971
The remainder is 515 after subtracting 535 from 1050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

Moving on to step 14:
If we divide 5150 by 535, we get 9 and a remainder of 335.
The number 9 becomes the next digit in our result. 
Result so far: 151987.689719
Subtracting 4815 from 5150 leaves us with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

On to step 15:
535 can be fit into 3350 6 times, resulting in a remainder of 140.
Put 6 as the next digit of the answer. 
Result so far: 151987.6897196
The remainder is 140 after subtracting 3210 from 3350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 16:
535 goes into 1400 2 times with a remainder of 330.
The number 2 becomes the next digit in our result. 
Result so far: 151987.68971962
The remainder is 330 after subtracting 1070 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

The final result is 151987.68971962 with a remainder of 3.3e-07.
