845683 ÷ 81 
We're looking to find how many times 81 goes into 845683.

Step 1:
81 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 81

On to step 2:
84 divided by 81 is 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 81 away from 84, we end up with 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 81

On to step 3:
81 goes into 35 0 times with a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 10.0
Deduct 0 from 35 and we're left with 35.
Grab the next digit (6) from the dividend, add it to 35, then carry on: 356 / 81

Step 4:
When dividing 356 by 81, we get 4 with a remainder of 32.
The next digit of our result is 4. 
Result so far: 104.0
If we subtract 324 from 356, we get 32.
Bring next digit (8) of the dividend behind the 32 and repeat the process: 328 / 81

Moving on to step 5:
If we divide 328 by 81, we get 4 and a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 1044.0
If we take 324 away from 328, we end up with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 81

Advancing to step 6:
43 divided by 81 is 0 with a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 10440.0
Deduct 0 from 43 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 7:
430 divided by 81 is 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 10440.5
Subtracting 405 from 430 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 8:
If we divide 250 by 81, we get 3 and a remainder of 7.
The next digit of our result is 3. 
Result so far: 10440.53
Subtracting 243 from 250 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 9:
81 can be fit into 70 0 times, resulting in a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 10440.53
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 10:
700 divided by 81 is 8 with a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 10440.5308
If we subtract 648 from 700, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 11:
The number 81 fits into 520 6 times, leaving a remainder of 34.
Put 6 as the next digit of the answer. 
Result so far: 10440.53086
Subtract 486 from 520 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 12:
81 can be fit into 340 4 times, resulting in a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 10440.530864
If we take 324 away from 340, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 13:
If we divide 160 by 81, we get 1 and a remainder of 79.
Put 1 as the next digit of the answer. 
Result so far: 10440.5308641
Subtracting 81 from 160 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 14:
When dividing 790 by 81, we get 9 with a remainder of 61.
Use 9 as the next digit of our solution. 
Result so far: 10440.53086419
If we subtract 729 from 790, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Our division results in 10440.53086419 with a remaining 6.1e-08.
