We divide 87664539 by 817
Our goal is to divide 87664539 by 817.

Going ahead to step 1:
The number 817 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 817

Moving on to step 2:
87 divided by 817 is 0 with a remainder of 87.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 87 after subtracting 0 from 87.
Append the next digit (6) from the dividend to 87 and continue with: 876 / 817

Moving on to step 3:
The number 817 fits into 876 1 times, leaving a remainder of 59.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 817 from 876 and we're left with 59.
Append the next digit (6) from the dividend to 59 and continue with: 596 / 817

Moving on to step 4:
If we divide 596 by 817, we get 0 and a remainder of 596.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we subtract 0 from 596, we get 596.
Include the next digit (4) from the dividend after 596, then repeat: 5964 / 817

Advancing to step 5:
817 goes into 5964 7 times with a remainder of 245.
Use 7 as the next digit of our solution. 
Result so far: 107.0
Subtracting 5719 from 5964 leaves us with 245.
Fetch the next digit (5) from the dividend, attach it to 245 and continue: 2455 / 817

Moving on to step 6:
When dividing 2455 by 817, we get 3 with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 1073.0
If we subtract 2451 from 2455, we get 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 817

Let's proceed to step 7:
When dividing 43 by 817, we get 0 with a remainder of 43.
The next digit of our result is 0. 
Result so far: 10730.0
Subtracting 0 from 43 leaves us with 43.
Take the next digit (9) from the dividend and append it to 43, then repeat: 439 / 817

Let's proceed to step 8:
439 divided by 817 is 0 with a remainder of 439.
Use 0 as the next digit of our solution. 
Result so far: 107300.0
Subtracting 0 from 439 leaves us with 439.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4390, and continue the process.

Step 9:
4390 divided by 817 is 5 with a remainder of 305.
Record the quotient 5 as the next digit in the result. 
Result so far: 107300.5
The remainder is 305 after subtracting 4085 from 4390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Going ahead to step 10:
If we divide 3050 by 817, we get 3 and a remainder of 599.
Use 3 as the next digit of our solution. 
Result so far: 107300.53
Subtract 2451 from 3050 to get 599.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5990, and continue the process.

On to step 11:
The number 817 fits into 5990 7 times, leaving a remainder of 271.
Record the quotient 7 as the next digit in the result. 
Result so far: 107300.537
If we subtract 5719 from 5990, we get 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Let's proceed to step 12:
If we divide 2710 by 817, we get 3 and a remainder of 259.
The number 3 becomes the next digit in our result. 
Result so far: 107300.5373
Subtracting 2451 from 2710 leaves us with 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Advancing to step 13:
If we divide 2590 by 817, we get 3 and a remainder of 139.
Put 3 as the next digit of the answer. 
Result so far: 107300.53733
If we subtract 2451 from 2590, we get 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Our division results in 107300.53733 with a remaining 0.000139.
