36809087 ÷ 688 
We want to divide 36809087 by 688.

Going ahead to step 1:
When dividing 3 by 688, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 688

Step 2:
If we divide 36 by 688, we get 0 and a remainder of 36.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 36 after subtracting 0 from 36.
Include the next digit (8) from the dividend after 36, then repeat: 368 / 688

On to step 3:
When dividing 368 by 688, we get 0 with a remainder of 368.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 368, we get 368.
Grab the next digit (0) from the dividend, add it to 368, then carry on: 3680 / 688

Let's proceed to step 4:
688 can be fit into 3680 5 times, resulting in a remainder of 240.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 3440 from 3680 and we're left with 240.
Fetch the next digit (9) from the dividend, attach it to 240 and continue: 2409 / 688

Advancing to step 5:
688 can be fit into 2409 3 times, resulting in a remainder of 345.
Write down 3 as next digit of the result. 
Result so far: 53.0
If we take 2064 away from 2409, we end up with 345.
Grab the next digit (0) from the dividend, add it to 345, then carry on: 3450 / 688

Going ahead to step 6:
If we divide 3450 by 688, we get 5 and a remainder of 10.
The next digit of our result is 5. 
Result so far: 535.0
Subtracting 3440 from 3450 leaves us with 10.
Include the next digit (8) from the dividend after 10, then repeat: 108 / 688

Moving on to step 7:
If we divide 108 by 688, we get 0 and a remainder of 108.
Put 0 as the next digit of the answer. 
Result so far: 5350.0
Subtract 0 from 108 to get 108.
Take the next digit (7) from the dividend and append it to 108, then repeat: 1087 / 688

Advancing to step 8:
The number 688 fits into 1087 1 times, leaving a remainder of 399.
Write down 1 as next digit of the result. 
Result so far: 53501.0
If we take 688 away from 1087, we end up with 399.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3990, and continue the process.

Advancing to step 9:
688 goes into 3990 5 times with a remainder of 550.
Record the quotient 5 as the next digit in the result. 
Result so far: 53501.5
If we take 3440 away from 3990, we end up with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

On to step 10:
688 can be fit into 5500 7 times, resulting in a remainder of 684.
Record the quotient 7 as the next digit in the result. 
Result so far: 53501.57
Subtract 4816 from 5500 to get 684.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6840, and continue the process.

Step 11:
The number 688 fits into 6840 9 times, leaving a remainder of 648.
Write down 9 as next digit of the result. 
Result so far: 53501.579
Subtract 6192 from 6840 to get 648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

Step 12:
When dividing 6480 by 688, we get 9 with a remainder of 288.
Record the quotient 9 as the next digit in the result. 
Result so far: 53501.5799
If we subtract 6192 from 6480, we get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

After the division, we end up with 53501.5799 and a remainder of 0.00288.
