12086 ÷ 49 
We want to figure out the number of times 12086 can be divided by 49.

Step 1:
1 divided by 49 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 49

Step 2:
When dividing 12 by 49, we get 0 with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Fetch the next digit (0) from the dividend, attach it to 12 and continue: 120 / 49

Advancing to step 3:
The number 49 fits into 120 2 times, leaving a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 98 from 120 to get 22.
Take the next digit (8) from the dividend and append it to 22, then repeat: 228 / 49

Advancing to step 4:
228 divided by 49 is 4 with a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
Subtract 196 from 228 to get 32.
Include the next digit (6) from the dividend after 32, then repeat: 326 / 49

Let's proceed to step 5:
49 goes into 326 6 times with a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 246.0
Deduct 294 from 326 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 6:
If we divide 320 by 49, we get 6 and a remainder of 26.
Use 6 as the next digit of our solution. 
Result so far: 246.6
Deduct 294 from 320 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 7:
260 divided by 49 is 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 246.65
If we subtract 245 from 260, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 8:
When dividing 150 by 49, we get 3 with a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 246.653
If we subtract 147 from 150, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 9:
If we divide 30 by 49, we get 0 and a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 246.653
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 10:
49 can be fit into 300 6 times, resulting in a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 246.65306
Subtracting 294 from 300 leaves us 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.

Advancing to step 11:
The number 49 fits into 60 1 times, leaving a remainder of 11.
The next digit of our result is 1. 
Result so far: 246.653061
If we subtract 49 from 60, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 12:
110 divided by 49 is 2 with a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 246.6530612
Subtracting 98 from 110 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 13:
120 divided by 49 is 2 with a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 246.65306122
Deduct 98 from 120 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.

Our division results in 246.65306122 with a remaining 2.2e-08.
