We're dividing 79398740 by 154 
Let's see how many times 154 fits into 79398740.

Advancing to step 1:
154 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 154

Moving on to step 2:
154 goes into 79 0 times with a remainder of 79.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 79 leaves us with 79.
Include the next digit (3) from the dividend after 79, then repeat: 793 / 154

Going ahead to step 3:
793 divided by 154 is 5 with a remainder of 23.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 770 from 793 leaves us with 23.
Fetch the next digit (9) from the dividend, attach it to 23 and continue: 239 / 154

Advancing to step 4:
154 goes into 239 1 times with a remainder of 85.
The next digit of our result is 1. 
Result so far: 51.0
Subtracting 154 from 239 leaves us with 85.
Take the next digit (8) from the dividend and append it to 85, then repeat: 858 / 154

On to step 5:
If we divide 858 by 154, we get 5 and a remainder of 88.
Record the quotient 5 as the next digit in the result. 
Result so far: 515.0
Subtract 770 from 858 to get 88.
Take the next digit (7) from the dividend and append it to 88, then repeat: 887 / 154

On to step 6:
When dividing 887 by 154, we get 5 with a remainder of 117.
Put 5 as the next digit of the answer. 
Result so far: 5155.0
Subtracting 770 from 887 leaves us with 117.
Take the next digit (4) from the dividend and append it to 117, then repeat: 1174 / 154

Let's proceed to step 7:
If we divide 1174 by 154, we get 7 and a remainder of 96.
Put 7 as the next digit of the answer. 
Result so far: 51557.0
If we take 1078 away from 1174, we end up with 96.
Take the next digit (0) from the dividend and append it to 96, then repeat: 960 / 154

On to step 8:
When dividing 960 by 154, we get 6 with a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 515576.0
The remainder is 36 after subtracting 924 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 9:
154 can be fit into 360 2 times, resulting in a remainder of 52.
Record the quotient 2 as the next digit in the result. 
Result so far: 515576.2
If we subtract 308 from 360, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 10:
The number 154 fits into 520 3 times, leaving a remainder of 58.
Use 3 as the next digit of our solution. 
Result so far: 515576.23
Subtract 462 from 520 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 11:
154 goes into 580 3 times with a remainder of 118.
The number 3 becomes the next digit in our result. 
Result so far: 515576.233
The remainder is 118 after subtracting 462 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

After the division, we end up with 515576.233 and a remainder of 0.0118.
