821600 ÷ 86 
We want to divide 821600 by 86.

Going ahead to step 1:
86 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 86

Step 2:
86 can be fit into 82 0 times, resulting in a remainder of 82.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 82 leaves us with 82.
Bring next digit (1) of the dividend behind the 82 and repeat the process: 821 / 86

On to step 3:
821 divided by 86 is 9 with a remainder of 47.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 774 from 821, we get 47.
Fetch the next digit (6) from the dividend, attach it to 47 and continue: 476 / 86

Step 4:
If we divide 476 by 86, we get 5 and a remainder of 46.
Record the quotient 5 as the next digit in the result. 
Result so far: 95.0
The remainder is 46 after subtracting 430 from 476.
Bring next digit (0) of the dividend behind the 46 and repeat the process: 460 / 86

On to step 5:
460 divided by 86 is 5 with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 955.0
Subtracting 430 from 460 leaves us with 30.
Take the next digit (0) from the dividend and append it to 30, then repeat: 300 / 86

Advancing to step 6:
When dividing 300 by 86, we get 3 with a remainder of 42.
Record the quotient 3 as the next digit in the result. 
Result so far: 9553.0
Deduct 258 from 300 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 7:
When dividing 420 by 86, we get 4 with a remainder of 76.
The number 4 becomes the next digit in our result. 
Result so far: 9553.4
The remainder is 76 after subtracting 344 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 8:
When dividing 760 by 86, we get 8 with a remainder of 72.
Use 8 as the next digit of our solution. 
Result so far: 9553.48
If we take 688 away from 760, we end up 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.

Moving on to step 9:
The number 86 fits into 720 8 times, leaving a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 9553.488
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 outcome is 9553.488, with a leftover of 0.0032.
