87273109 ÷ 690 
Our goal is to divide 87273109 by 690.

On to step 1:
When dividing 8 by 690, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 690

Going ahead to step 2:
When dividing 87 by 690, we get 0 with a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 87 after subtracting 0 from 87.
Take the next digit (2) from the dividend and append it to 87, then repeat: 872 / 690

Going ahead to step 3:
690 goes into 872 1 times with a remainder of 182.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 690 from 872 and we're left with 182.
Bring next digit (7) of the dividend behind the 182 and repeat the process: 1827 / 690

Step 4:
When dividing 1827 by 690, we get 2 with a remainder of 447.
The next digit of our result is 2. 
Result so far: 12.0
Subtract 1380 from 1827 to get 447.
Append the next digit (3) from the dividend to 447 and continue with: 4473 / 690

Advancing to step 5:
690 can be fit into 4473 6 times, resulting in a remainder of 333.
The number 6 becomes the next digit in our result. 
Result so far: 126.0
If we subtract 4140 from 4473, we get 333.
Grab the next digit (1) from the dividend, add it to 333, then carry on: 3331 / 690

Step 6:
690 can be fit into 3331 4 times, resulting in a remainder of 571.
Record the quotient 4 as the next digit in the result. 
Result so far: 1264.0
Subtracting 2760 from 3331 leaves us with 571.
Append the next digit (0) from the dividend to 571 and continue with: 5710 / 690

Advancing to step 7:
When dividing 5710 by 690, we get 8 with a remainder of 190.
Use 8 as the next digit of our solution. 
Result so far: 12648.0
Subtracting 5520 from 5710 leaves us with 190.
Grab the next digit (9) from the dividend, add it to 190, then carry on: 1909 / 690

On to step 8:
690 can be fit into 1909 2 times, resulting in a remainder of 529.
Put 2 as the next digit of the answer. 
Result so far: 126482.0
If we subtract 1380 from 1909, we get 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 9:
5290 divided by 690 is 7 with a remainder of 460.
Write down 7 as next digit of the result. 
Result so far: 126482.7
If we take 4830 away from 5290, we end up with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

On to step 10:
690 goes into 4600 6 times with a remainder of 460.
Use 6 as the next digit of our solution. 
Result so far: 126482.76
If we take 4140 away from 4600, we end up with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

On to step 11:
If we divide 4600 by 690, we get 6 and a remainder of 460.
Use 6 as the next digit of our solution. 
Result so far: 126482.766
Subtract 4140 from 4600 to get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

The final result is 126482.766 with a remainder of 0.046.
