417858 ÷ 79 
We want to figure out the number of times 417858 can be divided by 79.

Going ahead to step 1:
79 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 79

Step 2:
41 divided by 79 is 0 with a remainder of 41.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 41 after subtracting 0 from 41.
Fetch the next digit (7) from the dividend, attach it to 41 and continue: 417 / 79

Moving on to step 3:
417 divided by 79 is 5 with a remainder of 22.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 395 from 417 leaves us with 22.
Fetch the next digit (8) from the dividend, attach it to 22 and continue: 228 / 79

Let's proceed to step 4:
The number 79 fits into 228 2 times, leaving a remainder of 70.
Record the quotient 2 as the next digit in the result. 
Result so far: 52.0
If we take 158 away from 228, we end up with 70.
Append the next digit (5) from the dividend to 70 and continue with: 705 / 79

Step 5:
When dividing 705 by 79, we get 8 with a remainder of 73.
Write down 8 as next digit of the result. 
Result so far: 528.0
Subtract 632 from 705 to get 73.
Append the next digit (8) from the dividend to 73 and continue with: 738 / 79

Step 6:
79 can be fit into 738 9 times, resulting in a remainder of 27.
The number 9 becomes the next digit in our result. 
Result so far: 5289.0
If we subtract 711 from 738, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 7:
79 can be fit into 270 3 times, resulting in a remainder of 33.
Put 3 as the next digit of the answer. 
Result so far: 5289.3
The remainder is 33 after subtracting 237 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 8:
If we divide 330 by 79, we get 4 and a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 5289.34
The remainder is 14 after subtracting 316 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 9:
The number 79 fits into 140 1 times, leaving a remainder of 61.
The next digit of our result is 1. 
Result so far: 5289.341
If we take 79 away from 140, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 10:
When dividing 610 by 79, we get 7 with a remainder of 57.
Use 7 as the next digit of our solution. 
Result so far: 5289.3417
The remainder is 57 after subtracting 553 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 11:
79 goes into 570 7 times with a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 5289.34177
If we subtract 553 from 570, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The final result is 5289.34177 with a remainder of 1.7e-05.
