We look at the division of 78864779 by 458 
Let's see how many times 458 fits into 78864779.

Going ahead to step 1:
7 divided by 458 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 458

Advancing to step 2:
458 can be fit into 78 0 times, resulting in a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Append the next digit (8) from the dividend to 78 and continue with: 788 / 458

Going ahead to step 3:
If we divide 788 by 458, we get 1 and a remainder of 330.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 458 from 788 to get 330.
Append the next digit (6) from the dividend to 330 and continue with: 3306 / 458

Moving on to step 4:
When dividing 3306 by 458, we get 7 with a remainder of 100.
The next digit of our result is 7. 
Result so far: 17.0
Deduct 3206 from 3306 and we're left with 100.
Grab the next digit (4) from the dividend, add it to 100, then carry on: 1004 / 458

Going ahead to step 5:
1004 divided by 458 is 2 with a remainder of 88.
Put 2 as the next digit of the answer. 
Result so far: 172.0
If we subtract 916 from 1004, we get 88.
Fetch the next digit (7) from the dividend, attach it to 88 and continue: 887 / 458

Going ahead to step 6:
When dividing 887 by 458, we get 1 with a remainder of 429.
The number 1 becomes the next digit in our result. 
Result so far: 1721.0
If we subtract 458 from 887, we get 429.
Grab the next digit (7) from the dividend, add it to 429, then carry on: 4297 / 458

Going ahead to step 7:
When dividing 4297 by 458, we get 9 with a remainder of 175.
Record the quotient 9 as the next digit in the result. 
Result so far: 17219.0
If we take 4122 away from 4297, we end up with 175.
Include the next digit (9) from the dividend after 175, then repeat: 1759 / 458

Advancing to step 8:
If we divide 1759 by 458, we get 3 and a remainder of 385.
Use 3 as the next digit of our solution. 
Result so far: 172193.0
If we subtract 1374 from 1759, we get 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Step 9:
If we divide 3850 by 458, we get 8 and a remainder of 186.
The next digit of our result is 8. 
Result so far: 172193.8
Subtract 3664 from 3850 to get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Moving on to step 10:
When dividing 1860 by 458, we get 4 with a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 172193.84
The remainder is 28 after subtracting 1832 from 1860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 11:
If we divide 280 by 458, we get 0 and a remainder of 280.
Put 0 as the next digit of the answer. 
Result so far: 172193.84
The remainder is 280 after subtracting 0 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Let's proceed to step 12:
2800 divided by 458 is 6 with a remainder of 52.
Write down 6 as next digit of the result. 
Result so far: 172193.8406
Subtracting 2748 from 2800 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.

Going ahead to step 13:
458 goes into 520 1 times with a remainder of 62.
The next digit of our result is 1. 
Result so far: 172193.84061
Subtracting 458 from 520 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 14:
When dividing 620 by 458, we get 1 with a remainder of 162.
Put 1 as the next digit of the answer. 
Result so far: 172193.840611
Subtract 458 from 620 to get 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

The quotient of the division is 172193.840611, and the remainder is 1.62e-05.
