We look at the division of 478594 by 86 
We want to figure out the number of times 478594 can be divided by 86.

Moving on to step 1:
When dividing 4 by 86, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 86

On to step 2:
The number 86 fits into 47 0 times, leaving a remainder of 47.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 47 leaves us with 47.
Grab the next digit (8) from the dividend, add it to 47, then carry on: 478 / 86

Advancing to step 3:
478 divided by 86 is 5 with a remainder of 48.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 430 from 478, we get 48.
Fetch the next digit (5) from the dividend, attach it to 48 and continue: 485 / 86

Advancing to step 4:
485 divided by 86 is 5 with a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 55.0
If we take 430 away from 485, we end up with 55.
Fetch the next digit (9) from the dividend, attach it to 55 and continue: 559 / 86

Moving on to step 5:
The number 86 fits into 559 6 times, leaving a remainder of 43.
Write down 6 as next digit of the result. 
Result so far: 556.0
Deduct 516 from 559 and we're left with 43.
Append the next digit (4) from the dividend to 43 and continue with: 434 / 86

On to step 6:
If we divide 434 by 86, we get 5 and a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 5565.0
Subtracting 430 from 434 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 7:
86 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 5565.0
Subtract 0 from 40 to get 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 8:
If we divide 400 by 86, we get 4 and a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 5565.04
The remainder is 56 after subtracting 344 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 9:
86 goes into 560 6 times with a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 5565.046
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.

Moving on to step 10:
86 goes into 440 5 times with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 5565.0465
Subtract 430 from 440 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 11:
86 goes into 100 1 times with a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 5565.04651
The remainder is 14 after subtracting 86 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 12:
The number 86 fits into 140 1 times, leaving a remainder of 54.
Use 1 as the next digit of our solution. 
Result so far: 5565.046511
Subtracting 86 from 140 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Our division results in 5565.046511 with a remaining 5.4e-06.
