401891 ÷ 79 
We want to figure out the number of times 401891 can be divided by 79.

On to step 1:
4 divided by 79 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 79

Let's proceed to step 2:
When dividing 40 by 79, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Fetch the next digit (1) from the dividend, attach it to 40 and continue: 401 / 79

Step 3:
401 divided by 79 is 5 with a remainder of 6.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 395 from 401, we get 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 79

On to step 4:
If we divide 68 by 79, we get 0 and a remainder of 68.
Use 0 as the next digit of our solution. 
Result so far: 50.0
If we subtract 0 from 68, we get 68.
Fetch the next digit (9) from the dividend, attach it to 68 and continue: 689 / 79

Let's proceed to step 5:
If we divide 689 by 79, we get 8 and a remainder of 57.
Use 8 as the next digit of our solution. 
Result so far: 508.0
If we take 632 away from 689, we end up with 57.
Grab the next digit (1) from the dividend, add it to 57, then carry on: 571 / 79

Moving on to step 6:
The number 79 fits into 571 7 times, leaving a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 5087.0
Subtract 553 from 571 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 7:
If we divide 180 by 79, we get 2 and a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 5087.2
Subtract 158 from 180 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 8:
If we divide 220 by 79, we get 2 and a remainder of 62.
Use 2 as the next digit of our solution. 
Result so far: 5087.22
Subtract 158 from 220 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

The quotient of the division is 5087.22, and the remainder is 0.062.
