Let's divide 578343 by 86
We're looking to find how many times 86 goes into 578343.

Going ahead to step 1:
86 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 86

On to step 2:
The number 86 fits into 57 0 times, leaving a remainder of 57.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 57, we get 57.
Grab the next digit (8) from the dividend, add it to 57, then carry on: 578 / 86

Going ahead to step 3:
If we divide 578 by 86, we get 6 and a remainder of 62.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
The remainder is 62 after subtracting 516 from 578.
Fetch the next digit (3) from the dividend, attach it to 62 and continue: 623 / 86

Step 4:
When dividing 623 by 86, we get 7 with a remainder of 21.
The number 7 becomes the next digit in our result. 
Result so far: 67.0
If we subtract 602 from 623, we get 21.
Grab the next digit (4) from the dividend, add it to 21, then carry on: 214 / 86

Moving on to step 5:
214 divided by 86 is 2 with a remainder of 42.
The number 2 becomes the next digit in our result. 
Result so far: 672.0
Deduct 172 from 214 and we're left with 42.
Bring next digit (3) of the dividend behind the 42 and repeat the process: 423 / 86

Let's proceed to step 6:
If we divide 423 by 86, we get 4 and a remainder of 79.
Record the quotient 4 as the next digit in the result. 
Result so far: 6724.0
If we subtract 344 from 423, we get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 7:
790 divided by 86 is 9 with a remainder of 16.
Use 9 as the next digit of our solution. 
Result so far: 6724.9
If we take 774 away from 790, 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 8:
The number 86 fits into 160 1 times, leaving a remainder of 74.
Use 1 as the next digit of our solution. 
Result so far: 6724.91
The remainder is 74 after subtracting 86 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 9:
If we divide 740 by 86, we get 8 and a remainder of 52.
Use 8 as the next digit of our solution. 
Result so far: 6724.918
Subtracting 688 from 740 leaves us 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 10:
86 goes into 520 6 times with a remainder of 4.
The next digit of our result is 6. 
Result so far: 6724.9186
Subtracting 516 from 520 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 11:
If we divide 40 by 86, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 6724.9186
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 12:
400 divided by 86 is 4 with a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 6724.918604
Subtracting 344 from 400 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 13:
86 goes into 560 6 times with a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 6724.9186046
Subtract 516 from 560 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 14:
When dividing 440 by 86, we get 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 6724.91860465
Subtracting 430 from 440 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 6724.91860465, with a leftover of 1e-08.
