50011712 ÷ 121 
Our goal is to divide 50011712 by 121.

Step 1:
If we divide 5 by 121, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 121

Moving on to step 2:
50 divided by 121 is 0 with a remainder of 50.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 50 leaves us with 50.
Grab the next digit (0) from the dividend, add it to 50, then carry on: 500 / 121

Advancing to step 3:
The number 121 fits into 500 4 times, leaving a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 484 from 500 leaves us with 16.
Include the next digit (1) from the dividend after 16, then repeat: 161 / 121

On to step 4:
The number 121 fits into 161 1 times, leaving a remainder of 40.
Write down 1 as next digit of the result. 
Result so far: 41.0
If we take 121 away from 161, we end up with 40.
Fetch the next digit (1) from the dividend, attach it to 40 and continue: 401 / 121

Going ahead to step 5:
When dividing 401 by 121, we get 3 with a remainder of 38.
The next digit of our result is 3. 
Result so far: 413.0
Deduct 363 from 401 and we're left with 38.
Append the next digit (7) from the dividend to 38 and continue with: 387 / 121

On to step 6:
If we divide 387 by 121, we get 3 and a remainder of 24.
The number 3 becomes the next digit in our result. 
Result so far: 4133.0
If we take 363 away from 387, we end up with 24.
Bring next digit (1) of the dividend behind the 24 and repeat the process: 241 / 121

On to step 7:
The number 121 fits into 241 1 times, leaving a remainder of 120.
The next digit of our result is 1. 
Result so far: 41331.0
Subtracting 121 from 241 leaves us with 120.
Bring next digit (2) of the dividend behind the 120 and repeat the process: 1202 / 121

On to step 8:
When dividing 1202 by 121, we get 9 with a remainder of 113.
Record the quotient 9 as the next digit in the result. 
Result so far: 413319.0
Subtracting 1089 from 1202 leaves us with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Let's proceed to step 9:
121 can be fit into 1130 9 times, resulting in a remainder of 41.
The next digit of our result is 9. 
Result so far: 413319.9
If we subtract 1089 from 1130, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 10:
410 divided by 121 is 3 with a remainder of 47.
Record the quotient 3 as the next digit in the result. 
Result so far: 413319.93
Deduct 363 from 410 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 11:
121 can be fit into 470 3 times, resulting in a remainder of 107.
Record the quotient 3 as the next digit in the result. 
Result so far: 413319.933
Subtracting 363 from 470 leaves us with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

The quotient of the division is 413319.933, and the remainder is 0.0107.
