We divide 671964 by 86
We want to figure out the number of times 671964 can be divided by 86.

Step 1:
If we divide 6 by 86, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 86

On to step 2:
If we divide 67 by 86, we get 0 and a remainder of 67.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 67 and we're left with 67.
Fetch the next digit (1) from the dividend, attach it to 67 and continue: 671 / 86

Advancing to step 3:
The number 86 fits into 671 7 times, leaving a remainder of 69.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 602 from 671 and we're left with 69.
Grab the next digit (9) from the dividend, add it to 69, then carry on: 699 / 86

Advancing to step 4:
The number 86 fits into 699 8 times, leaving a remainder of 11.
Record the quotient 8 as the next digit in the result. 
Result so far: 78.0
Deduct 688 from 699 and we're left with 11.
Grab the next digit (6) from the dividend, add it to 11, then carry on: 116 / 86

On to step 5:
When dividing 116 by 86, we get 1 with a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 781.0
If we subtract 86 from 116, we get 30.
Take the next digit (4) from the dividend and append it to 30, then repeat: 304 / 86

Going ahead to step 6:
86 can be fit into 304 3 times, resulting in a remainder of 46.
Record the quotient 3 as the next digit in the result. 
Result so far: 7813.0
Subtracting 258 from 304 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 7:
86 goes into 460 5 times with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 7813.5
If we subtract 430 from 460, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
86 goes into 300 3 times with a remainder of 42.
The next digit of our result is 3. 
Result so far: 7813.53
If we subtract 258 from 300, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 9:
If we divide 420 by 86, we get 4 and a remainder of 76.
The next digit of our result is 4. 
Result so far: 7813.534
Deduct 344 from 420 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 10:
The number 86 fits into 760 8 times, leaving a remainder of 72.
The number 8 becomes the next digit in our result. 
Result so far: 7813.5348
Deduct 688 from 760 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 11:
When dividing 720 by 86, we get 8 with a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 7813.53488
If we subtract 688 from 720, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 7813.53488 with a remainder of 3.2e-05.
