We look at the division of 86409495 by 479 
Our goal is to divide 86409495 by 479.

Advancing to step 1:
8 divided by 479 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 479

Going ahead to step 2:
86 divided by 479 is 0 with a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Take the next digit (4) from the dividend and append it to 86, then repeat: 864 / 479

Moving on to step 3:
When dividing 864 by 479, we get 1 with a remainder of 385.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 479 from 864, we get 385.
Grab the next digit (0) from the dividend, add it to 385, then carry on: 3850 / 479

Step 4:
If we divide 3850 by 479, we get 8 and a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Subtracting 3832 from 3850 leaves us with 18.
Grab the next digit (9) from the dividend, add it to 18, then carry on: 189 / 479

On to step 5:
479 goes into 189 0 times with a remainder of 189.
Use 0 as the next digit of our solution. 
Result so far: 180.0
Subtract 0 from 189 to get 189.
Include the next digit (4) from the dividend after 189, then repeat: 1894 / 479

Moving on to step 6:
The number 479 fits into 1894 3 times, leaving a remainder of 457.
Record the quotient 3 as the next digit in the result. 
Result so far: 1803.0
If we take 1437 away from 1894, we end up with 457.
Fetch the next digit (9) from the dividend, attach it to 457 and continue: 4579 / 479

Let's proceed to step 7:
479 goes into 4579 9 times with a remainder of 268.
The number 9 becomes the next digit in our result. 
Result so far: 18039.0
Subtracting 4311 from 4579 leaves us with 268.
Fetch the next digit (5) from the dividend, attach it to 268 and continue: 2685 / 479

Let's proceed to step 8:
479 can be fit into 2685 5 times, resulting in a remainder of 290.
The number 5 becomes the next digit in our result. 
Result so far: 180395.0
Subtract 2395 from 2685 to get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

On to step 9:
The number 479 fits into 2900 6 times, leaving a remainder of 26.
Use 6 as the next digit of our solution. 
Result so far: 180395.6
Subtracting 2874 from 2900 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 10:
If we divide 260 by 479, we get 0 and a remainder of 260.
Write down 0 as next digit of the result. 
Result so far: 180395.6
If we take 0 away from 260, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Advancing to step 11:
2600 divided by 479 is 5 with a remainder of 205.
The number 5 becomes the next digit in our result. 
Result so far: 180395.605
Deduct 2395 from 2600 and we're left with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Advancing to step 12:
If we divide 2050 by 479, we get 4 and a remainder of 134.
The number 4 becomes the next digit in our result. 
Result so far: 180395.6054
The remainder is 134 after subtracting 1916 from 2050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Let's proceed to step 13:
479 can be fit into 1340 2 times, resulting in a remainder of 382.
Use 2 as the next digit of our solution. 
Result so far: 180395.60542
Subtract 958 from 1340 to get 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Step 14:
The number 479 fits into 3820 7 times, leaving a remainder of 467.
Use 7 as the next digit of our solution. 
Result so far: 180395.605427
The remainder is 467 after subtracting 3353 from 3820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4670, and continue the process.

Let's proceed to step 15:
If we divide 4670 by 479, we get 9 and a remainder of 359.
Write down 9 as next digit of the result. 
Result so far: 180395.6054279
Subtract 4311 from 4670 to get 359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

Moving on to step 16:
479 can be fit into 3590 7 times, resulting in a remainder of 237.
Record the quotient 7 as the next digit in the result. 
Result so far: 180395.60542797
If we take 3353 away from 3590, we end up with 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

Our division results in 180395.60542797 with a remaining 2.37e-07.
