Let's divide 81544523 by 690
We want to divide 81544523 by 690.

Advancing to step 1:
8 divided by 690 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 690

Moving on to step 2:
690 goes into 81 0 times with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Grab the next digit (5) from the dividend, add it to 81, then carry on: 815 / 690

Step 3:
815 divided by 690 is 1 with a remainder of 125.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 125 after subtracting 690 from 815.
Include the next digit (4) from the dividend after 125, then repeat: 1254 / 690

Advancing to step 4:
If we divide 1254 by 690, we get 1 and a remainder of 564.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtract 690 from 1254 to get 564.
Include the next digit (4) from the dividend after 564, then repeat: 5644 / 690

On to step 5:
If we divide 5644 by 690, we get 8 and a remainder of 124.
Put 8 as the next digit of the answer. 
Result so far: 118.0
The remainder is 124 after subtracting 5520 from 5644.
Fetch the next digit (5) from the dividend, attach it to 124 and continue: 1245 / 690

Going ahead to step 6:
If we divide 1245 by 690, we get 1 and a remainder of 555.
Put 1 as the next digit of the answer. 
Result so far: 1181.0
The remainder is 555 after subtracting 690 from 1245.
Take the next digit (2) from the dividend and append it to 555, then repeat: 5552 / 690

Advancing to step 7:
5552 divided by 690 is 8 with a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 11818.0
The remainder is 32 after subtracting 5520 from 5552.
Bring next digit (3) of the dividend behind the 32 and repeat the process: 323 / 690

Going ahead to step 8:
323 divided by 690 is 0 with a remainder of 323.
Use 0 as the next digit of our solution. 
Result so far: 118180.0
If we subtract 0 from 323, we get 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

Moving on to step 9:
690 can be fit into 3230 4 times, resulting in a remainder of 470.
Write down 4 as next digit of the result. 
Result so far: 118180.4
Subtract 2760 from 3230 to get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Going ahead to step 10:
690 can be fit into 4700 6 times, resulting in a remainder of 560.
Write down 6 as next digit of the result. 
Result so far: 118180.46
Subtract 4140 from 4700 to get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Step 11:
5600 divided by 690 is 8 with a remainder of 80.
Write down 8 as next digit of the result. 
Result so far: 118180.468
Subtracting 5520 from 5600 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 12:
690 can be fit into 800 1 times, resulting in a remainder of 110.
Write down 1 as next digit of the result. 
Result so far: 118180.4681
If we take 690 away from 800, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 13:
1100 divided by 690 is 1 with a remainder of 410.
The number 1 becomes the next digit in our result. 
Result so far: 118180.46811
If we subtract 690 from 1100, we get 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

The final outcome is 118180.46811, with a leftover of 0.00041.
