We're dividing 123192 by 49 
We want to figure out the number of times 123192 can be divided by 49.

Advancing to step 1:
49 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 49

Going ahead to step 2:
12 divided by 49 is 0 with a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Include the next digit (3) from the dividend after 12, then repeat: 123 / 49

Going ahead to step 3:
49 can be fit into 123 2 times, resulting in a remainder of 25.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 98 from 123 and we're left with 25.
Fetch the next digit (1) from the dividend, attach it to 25 and continue: 251 / 49

Going ahead to step 4:
251 divided by 49 is 5 with a remainder of 6.
Use 5 as the next digit of our solution. 
Result so far: 25.0
Deduct 245 from 251 and we're left with 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 49

Advancing to step 5:
69 divided by 49 is 1 with a remainder of 20.
The next digit of our result is 1. 
Result so far: 251.0
If we take 49 away from 69, we end up with 20.
Take the next digit (2) from the dividend and append it to 20, then repeat: 202 / 49

On to step 6:
When dividing 202 by 49, we get 4 with a remainder of 6.
The next digit of our result is 4. 
Result so far: 2514.0
Deduct 196 from 202 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 7:
When dividing 60 by 49, we get 1 with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 2514.1
Deduct 49 from 60 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 8:
The number 49 fits into 110 2 times, leaving a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 2514.12
The remainder is 12 after subtracting 98 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 9:
49 can be fit into 120 2 times, resulting in a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 2514.122
The remainder is 22 after subtracting 98 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

After the division, we end up with 2514.122 and a remainder of 0.0022.
