86421360 ÷ 496 
We want to figure out the number of times 86421360 can be divided by 496.

Advancing to step 1:
496 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 496

Going ahead to step 2:
496 goes into 86 0 times with a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Take the next digit (4) from the dividend and append it to 86, then repeat: 864 / 496

Let's proceed to step 3:
The number 496 fits into 864 1 times, leaving a remainder of 368.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 496 from 864 and we're left with 368.
Include the next digit (2) from the dividend after 368, then repeat: 3682 / 496

Let's proceed to step 4:
When dividing 3682 by 496, we get 7 with a remainder of 210.
Write down 7 as next digit of the result. 
Result so far: 17.0
If we take 3472 away from 3682, we end up with 210.
Bring next digit (1) of the dividend behind the 210 and repeat the process: 2101 / 496

Step 5:
The number 496 fits into 2101 4 times, leaving a remainder of 117.
Write down 4 as next digit of the result. 
Result so far: 174.0
The remainder is 117 after subtracting 1984 from 2101.
Take the next digit (3) from the dividend and append it to 117, then repeat: 1173 / 496

Moving on to step 6:
The number 496 fits into 1173 2 times, leaving a remainder of 181.
Record the quotient 2 as the next digit in the result. 
Result so far: 1742.0
Subtract 992 from 1173 to get 181.
Grab the next digit (6) from the dividend, add it to 181, then carry on: 1816 / 496

Moving on to step 7:
496 can be fit into 1816 3 times, resulting in a remainder of 328.
Use 3 as the next digit of our solution. 
Result so far: 17423.0
Subtract 1488 from 1816 to get 328.
Include the next digit (0) from the dividend after 328, then repeat: 3280 / 496

Step 8:
When dividing 3280 by 496, we get 6 with a remainder of 304.
Use 6 as the next digit of our solution. 
Result so far: 174236.0
Subtracting 2976 from 3280 leaves us with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Moving on to step 9:
3040 divided by 496 is 6 with a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 174236.6
Subtract 2976 from 3040 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 10:
496 can be fit into 640 1 times, resulting in a remainder of 144.
Put 1 as the next digit of the answer. 
Result so far: 174236.61
The remainder is 144 after subtracting 496 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Step 11:
If we divide 1440 by 496, we get 2 and a remainder of 448.
Write down 2 as next digit of the result. 
Result so far: 174236.612
If we take 992 away from 1440, we end up with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Step 12:
496 goes into 4480 9 times with a remainder of 16.
Record the quotient 9 as the next digit in the result. 
Result so far: 174236.6129
If we subtract 4464 from 4480, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 13:
496 goes into 160 0 times with a remainder of 160.
Use 0 as the next digit of our solution. 
Result so far: 174236.6129
If we take 0 away from 160, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 14:
When dividing 1600 by 496, we get 3 with a remainder of 112.
The number 3 becomes the next digit in our result. 
Result so far: 174236.612903
If we subtract 1488 from 1600, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Let's proceed to step 15:
496 can be fit into 1120 2 times, resulting in a remainder of 128.
Use 2 as the next digit of our solution. 
Result so far: 174236.6129032
If we subtract 992 from 1120, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Advancing to step 16:
If we divide 1280 by 496, we get 2 and a remainder of 288.
The number 2 becomes the next digit in our result. 
Result so far: 174236.61290322
Subtract 992 from 1280 to get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Our division results in 174236.61290322 with a remaining 2.88e-07.
