53101213 ÷ 122 
Let's see how many times 122 fits into 53101213.

Advancing to step 1:
The number 122 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 122

Let's proceed to step 2:
The number 122 fits into 53 0 times, leaving a remainder of 53.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 53 to get 53.
Fetch the next digit (1) from the dividend, attach it to 53 and continue: 531 / 122

Advancing to step 3:
If we divide 531 by 122, we get 4 and a remainder of 43.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 488 from 531, we get 43.
Fetch the next digit (0) from the dividend, attach it to 43 and continue: 430 / 122

Going ahead to step 4:
The number 122 fits into 430 3 times, leaving a remainder of 64.
The next digit of our result is 3. 
Result so far: 43.0
Deduct 366 from 430 and we're left with 64.
Append the next digit (1) from the dividend to 64 and continue with: 641 / 122

Let's proceed to step 5:
When dividing 641 by 122, we get 5 with a remainder of 31.
Use 5 as the next digit of our solution. 
Result so far: 435.0
Deduct 610 from 641 and we're left with 31.
Include the next digit (2) from the dividend after 31, then repeat: 312 / 122

Let's proceed to step 6:
122 goes into 312 2 times with a remainder of 68.
Write down 2 as next digit of the result. 
Result so far: 4352.0
Subtract 244 from 312 to get 68.
Fetch the next digit (1) from the dividend, attach it to 68 and continue: 681 / 122

Moving on to step 7:
122 can be fit into 681 5 times, resulting in a remainder of 71.
Use 5 as the next digit of our solution. 
Result so far: 43525.0
If we subtract 610 from 681, we get 71.
Include the next digit (3) from the dividend after 71, then repeat: 713 / 122

Let's proceed to step 8:
122 goes into 713 5 times with a remainder of 103.
Write down 5 as next digit of the result. 
Result so far: 435255.0
Deduct 610 from 713 and we're left with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Advancing to step 9:
1030 divided by 122 is 8 with a remainder of 54.
Use 8 as the next digit of our solution. 
Result so far: 435255.8
Deduct 976 from 1030 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 10:
122 goes into 540 4 times with a remainder of 52.
The number 4 becomes the next digit in our result. 
Result so far: 435255.84
If we take 488 away from 540, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 11:
When dividing 520 by 122, we get 4 with a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 435255.844
If we take 488 away from 520, we end up 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.

The quotient of the division is 435255.844, and the remainder is 0.0032.
