We're dividing 52309687 by 689 
Our goal is to divide 52309687 by 689.

On to step 1:
689 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 689

On to step 2:
The number 689 fits into 52 0 times, leaving a remainder of 52.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 52, we get 52.
Grab the next digit (3) from the dividend, add it to 52, then carry on: 523 / 689

Advancing to step 3:
523 divided by 689 is 0 with a remainder of 523.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 523 leaves us with 523.
Append the next digit (0) from the dividend to 523 and continue with: 5230 / 689

Let's proceed to step 4:
689 goes into 5230 7 times with a remainder of 407.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 4823 from 5230 and we're left with 407.
Fetch the next digit (9) from the dividend, attach it to 407 and continue: 4079 / 689

Going ahead to step 5:
When dividing 4079 by 689, we get 5 with a remainder of 634.
The number 5 becomes the next digit in our result. 
Result so far: 75.0
If we take 3445 away from 4079, we end up with 634.
Take the next digit (6) from the dividend and append it to 634, then repeat: 6346 / 689

Step 6:
6346 divided by 689 is 9 with a remainder of 145.
Put 9 as the next digit of the answer. 
Result so far: 759.0
If we subtract 6201 from 6346, we get 145.
Bring next digit (8) of the dividend behind the 145 and repeat the process: 1458 / 689

Going ahead to step 7:
689 can be fit into 1458 2 times, resulting in a remainder of 80.
The number 2 becomes the next digit in our result. 
Result so far: 7592.0
Subtracting 1378 from 1458 leaves us with 80.
Grab the next digit (7) from the dividend, add it to 80, then carry on: 807 / 689

Advancing to step 8:
807 divided by 689 is 1 with a remainder of 118.
The number 1 becomes the next digit in our result. 
Result so far: 75921.0
Deduct 689 from 807 and we're left with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Let's proceed to step 9:
When dividing 1180 by 689, we get 1 with a remainder of 491.
Record the quotient 1 as the next digit in the result. 
Result so far: 75921.1
Deduct 689 from 1180 and we're left with 491.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4910, and continue the process.

Step 10:
689 can be fit into 4910 7 times, resulting in a remainder of 87.
Use 7 as the next digit of our solution. 
Result so far: 75921.17
The remainder is 87 after subtracting 4823 from 4910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Moving on to step 11:
689 goes into 870 1 times with a remainder of 181.
Put 1 as the next digit of the answer. 
Result so far: 75921.171
If we subtract 689 from 870, we get 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Advancing to step 12:
If we divide 1810 by 689, we get 2 and a remainder of 432.
The next digit of our result is 2. 
Result so far: 75921.1712
If we subtract 1378 from 1810, we get 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Moving on to step 13:
4320 divided by 689 is 6 with a remainder of 186.
Put 6 as the next digit of the answer. 
Result so far: 75921.17126
If we subtract 4134 from 4320, we get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Let's proceed to step 14:
689 can be fit into 1860 2 times, resulting in a remainder of 482.
The number 2 becomes the next digit in our result. 
Result so far: 75921.171262
The remainder is 482 after subtracting 1378 from 1860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Moving on to step 15:
The number 689 fits into 4820 6 times, leaving a remainder of 686.
The number 6 becomes the next digit in our result. 
Result so far: 75921.1712626
Deduct 4134 from 4820 and we're left with 686.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6860, and continue the process.

On to step 16:
689 goes into 6860 9 times with a remainder of 659.
Write down 9 as next digit of the result. 
Result so far: 75921.17126269
If we subtract 6201 from 6860, we get 659.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6590, and continue the process.

After the division, we end up with 75921.17126269 and a remainder of 6.59e-07.
