451616 ÷ 86 
We want to figure out the number of times 451616 can be divided by 86.

Advancing to step 1:
4 divided by 86 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 86

Let's proceed to step 2:
When dividing 45 by 86, we get 0 with a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Include the next digit (1) from the dividend after 45, then repeat: 451 / 86

On to step 3:
86 goes into 451 5 times with a remainder of 21.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 430 from 451 to get 21.
Include the next digit (6) from the dividend after 21, then repeat: 216 / 86

Let's proceed to step 4:
86 can be fit into 216 2 times, resulting in a remainder of 44.
Use 2 as the next digit of our solution. 
Result so far: 52.0
If we take 172 away from 216, we end up with 44.
Grab the next digit (1) from the dividend, add it to 44, then carry on: 441 / 86

On to step 5:
86 goes into 441 5 times with a remainder of 11.
The next digit of our result is 5. 
Result so far: 525.0
Subtract 430 from 441 to get 11.
Grab the next digit (6) from the dividend, add it to 11, then carry on: 116 / 86

On to step 6:
86 can be fit into 116 1 times, resulting in a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 5251.0
The remainder is 30 after subtracting 86 from 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 7:
The number 86 fits into 300 3 times, leaving a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 5251.3
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.

Step 8:
If we divide 420 by 86, we get 4 and a remainder of 76.
Record the quotient 4 as the next digit in the result. 
Result so far: 5251.34
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.

Let's proceed to step 9:
86 goes into 760 8 times with a remainder of 72.
The next digit of our result is 8. 
Result so far: 5251.348
Subtracting 688 from 760 leaves us 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.

Let's proceed to step 10:
720 divided by 86 is 8 with a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 5251.3488
Deduct 688 from 720 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

In conclusion, the division gives 5251.3488 with a balance of 0.00032.
