670975 divided by 81 
We're looking to find how many times 81 goes into 670975.

On to step 1:
81 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 81

Moving on to step 2:
If we divide 67 by 81, we get 0 and a remainder of 67.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 67, we end up with 67.
Take the next digit (0) from the dividend and append it to 67, then repeat: 670 / 81

Moving on to step 3:
81 can be fit into 670 8 times, resulting in a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we take 648 away from 670, we end up with 22.
Include the next digit (9) from the dividend after 22, then repeat: 229 / 81

Going ahead to step 4:
When dividing 229 by 81, we get 2 with a remainder of 67.
Use 2 as the next digit of our solution. 
Result so far: 82.0
The remainder is 67 after subtracting 162 from 229.
Take the next digit (7) from the dividend and append it to 67, then repeat: 677 / 81

Step 5:
When dividing 677 by 81, we get 8 with a remainder of 29.
The next digit of our result is 8. 
Result so far: 828.0
Subtracting 648 from 677 leaves us with 29.
Append the next digit (5) from the dividend to 29 and continue with: 295 / 81

Step 6:
81 can be fit into 295 3 times, resulting in a remainder of 52.
The number 3 becomes the next digit in our result. 
Result so far: 8283.0
Deduct 243 from 295 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 7:
81 goes into 520 6 times with a remainder of 34.
The next digit of our result is 6. 
Result so far: 8283.6
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.

Going ahead to step 8:
The number 81 fits into 340 4 times, leaving a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 8283.64
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.

Advancing to step 9:
81 can be fit into 160 1 times, resulting in a remainder of 79.
The next digit of our result is 1. 
Result so far: 8283.641
The remainder is 79 after subtracting 81 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

On to step 10:
81 goes into 790 9 times with a remainder of 61.
Record the quotient 9 as the next digit in the result. 
Result so far: 8283.6419
Subtract 729 from 790 to 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.

Moving on to step 11:
If we divide 610 by 81, we get 7 and a remainder of 43.
Write down 7 as next digit of the result. 
Result so far: 8283.64197
If we subtract 567 from 610, we get 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 12:
If we divide 430 by 81, we get 5 and a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 8283.641975
The remainder is 25 after subtracting 405 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 13:
250 divided by 81 is 3 with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 8283.6419753
If we take 243 away from 250, we end up 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 14:
70 divided by 81 is 0 with a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 8283.6419753
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final outcome is 8283.6419753, with a leftover of 7e-08.
