155458 ÷ 79 
We're looking to find how many times 79 goes into 155458.

Step 1:
The number 79 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 79

Let's proceed to step 2:
The number 79 fits into 15 0 times, leaving a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Grab the next digit (5) from the dividend, add it to 15, then carry on: 155 / 79

On to step 3:
The number 79 fits into 155 1 times, leaving a remainder of 76.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 79 from 155, we get 76.
Include the next digit (4) from the dividend after 76, then repeat: 764 / 79

Advancing to step 4:
79 goes into 764 9 times with a remainder of 53.
Use 9 as the next digit of our solution. 
Result so far: 19.0
The remainder is 53 after subtracting 711 from 764.
Fetch the next digit (5) from the dividend, attach it to 53 and continue: 535 / 79

On to step 5:
The number 79 fits into 535 6 times, leaving a remainder of 61.
Write down 6 as next digit of the result. 
Result so far: 196.0
Subtracting 474 from 535 leaves us with 61.
Grab the next digit (8) from the dividend, add it to 61, then carry on: 618 / 79

Advancing to step 6:
79 can be fit into 618 7 times, resulting in a remainder of 65.
Put 7 as the next digit of the answer. 
Result so far: 1967.0
If we subtract 553 from 618, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 7:
The number 79 fits into 650 8 times, leaving a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 1967.8
The remainder is 18 after subtracting 632 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 8:
When dividing 180 by 79, we get 2 with a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 1967.82
Deduct 158 from 180 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 9:
The number 79 fits into 220 2 times, leaving a remainder of 62.
Put 2 as the next digit of the answer. 
Result so far: 1967.822
The remainder is 62 after subtracting 158 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

The final outcome is 1967.822, with a leftover of 0.0062.
