We look at the division of 35815920 by 689 
We're looking to find how many times 689 goes into 35815920.

Moving on to step 1:
3 divided by 689 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 689

Moving on to step 2:
689 goes into 35 0 times with a remainder of 35.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 35, we get 35.
Bring next digit (8) of the dividend behind the 35 and repeat the process: 358 / 689

Moving on to step 3:
358 divided by 689 is 0 with a remainder of 358.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 358, we end up with 358.
Include the next digit (1) from the dividend after 358, then repeat: 3581 / 689

Let's proceed to step 4:
The number 689 fits into 3581 5 times, leaving a remainder of 136.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 136 after subtracting 3445 from 3581.
Take the next digit (5) from the dividend and append it to 136, then repeat: 1365 / 689

Moving on to step 5:
689 goes into 1365 1 times with a remainder of 676.
Put 1 as the next digit of the answer. 
Result so far: 51.0
Subtract 689 from 1365 to get 676.
Fetch the next digit (9) from the dividend, attach it to 676 and continue: 6769 / 689

Going ahead to step 6:
When dividing 6769 by 689, we get 9 with a remainder of 568.
Use 9 as the next digit of our solution. 
Result so far: 519.0
Subtract 6201 from 6769 to get 568.
Grab the next digit (2) from the dividend, add it to 568, then carry on: 5682 / 689

On to step 7:
When dividing 5682 by 689, we get 8 with a remainder of 170.
Use 8 as the next digit of our solution. 
Result so far: 5198.0
Subtract 5512 from 5682 to get 170.
Fetch the next digit (0) from the dividend, attach it to 170 and continue: 1700 / 689

Advancing to step 8:
The number 689 fits into 1700 2 times, leaving a remainder of 322.
Put 2 as the next digit of the answer. 
Result so far: 51982.0
The remainder is 322 after subtracting 1378 from 1700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Going ahead to step 9:
689 can be fit into 3220 4 times, resulting in a remainder of 464.
Record the quotient 4 as the next digit in the result. 
Result so far: 51982.4
If we subtract 2756 from 3220, we get 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Let's proceed to step 10:
When dividing 4640 by 689, we get 6 with a remainder of 506.
The next digit of our result is 6. 
Result so far: 51982.46
The remainder is 506 after subtracting 4134 from 4640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

Let's proceed to step 11:
689 goes into 5060 7 times with a remainder of 237.
Use 7 as the next digit of our solution. 
Result so far: 51982.467
The remainder is 237 after subtracting 4823 from 5060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

On to step 12:
2370 divided by 689 is 3 with a remainder of 303.
The number 3 becomes the next digit in our result. 
Result so far: 51982.4673
Subtract 2067 from 2370 to get 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

On to step 13:
If we divide 3030 by 689, we get 4 and a remainder of 274.
Put 4 as the next digit of the answer. 
Result so far: 51982.46734
Subtracting 2756 from 3030 leaves us with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Step 14:
2740 divided by 689 is 3 with a remainder of 673.
Put 3 as the next digit of the answer. 
Result so far: 51982.467343
If we take 2067 away from 2740, we end up with 673.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6730, and continue the process.

Let's proceed to step 15:
If we divide 6730 by 689, we get 9 and a remainder of 529.
The number 9 becomes the next digit in our result. 
Result so far: 51982.4673439
Subtracting 6201 from 6730 leaves us with 529.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5290, and continue the process.

Moving on to step 16:
If we divide 5290 by 689, we get 7 and a remainder of 467.
Record the quotient 7 as the next digit in the result. 
Result so far: 51982.46734397
If we take 4823 away from 5290, we end up with 467.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4670, and continue the process.

The final outcome is 51982.46734397, with a leftover of 4.67e-07.
