We look at the division of 53169529 by 121 
Our goal is to divide 53169529 by 121.

Let's proceed to step 1:
If we divide 5 by 121, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 121

Moving on to step 2:
The number 121 fits into 53 0 times, leaving a remainder of 53.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Grab the next digit (1) from the dividend, add it to 53, then carry on: 531 / 121

Moving on to step 3:
When dividing 531 by 121, we get 4 with a remainder of 47.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 47 after subtracting 484 from 531.
Include the next digit (6) from the dividend after 47, then repeat: 476 / 121

Moving on to step 4:
When dividing 476 by 121, we get 3 with a remainder of 113.
Use 3 as the next digit of our solution. 
Result so far: 43.0
The remainder is 113 after subtracting 363 from 476.
Include the next digit (9) from the dividend after 113, then repeat: 1139 / 121

Let's proceed to step 5:
The number 121 fits into 1139 9 times, leaving a remainder of 50.
Write down 9 as next digit of the result. 
Result so far: 439.0
Deduct 1089 from 1139 and we're left with 50.
Grab the next digit (5) from the dividend, add it to 50, then carry on: 505 / 121

Let's proceed to step 6:
121 can be fit into 505 4 times, resulting in a remainder of 21.
Write down 4 as next digit of the result. 
Result so far: 4394.0
Subtract 484 from 505 to get 21.
Append the next digit (2) from the dividend to 21 and continue with: 212 / 121

On to step 7:
212 divided by 121 is 1 with a remainder of 91.
Record the quotient 1 as the next digit in the result. 
Result so far: 43941.0
Subtracting 121 from 212 leaves us with 91.
Include the next digit (9) from the dividend after 91, then repeat: 919 / 121

On to step 8:
The number 121 fits into 919 7 times, leaving a remainder of 72.
Write down 7 as next digit of the result. 
Result so far: 439417.0
Deduct 847 from 919 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 9:
121 can be fit into 720 5 times, resulting in a remainder of 115.
Use 5 as the next digit of our solution. 
Result so far: 439417.5
Subtracting 605 from 720 leaves us with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Moving on to step 10:
When dividing 1150 by 121, we get 9 with a remainder of 61.
Record the quotient 9 as the next digit in the result. 
Result so far: 439417.59
Subtract 1089 from 1150 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Let's proceed to step 11:
610 divided by 121 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 439417.595
If we take 605 away from 610, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 12:
121 goes into 50 0 times with a remainder of 50.
The next digit of our result is 0. 
Result so far: 439417.595
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 13:
121 can be fit into 500 4 times, resulting in a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 439417.59504
Deduct 484 from 500 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 14:
121 can be fit into 160 1 times, resulting in a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 439417.595041
If we subtract 121 from 160, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 15:
390 divided by 121 is 3 with a remainder of 27.
The next digit of our result is 3. 
Result so far: 439417.5950413
If we take 363 away from 390, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 16:
When dividing 270 by 121, we get 2 with a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 439417.59504132
The remainder is 28 after subtracting 242 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The quotient of the division is 439417.59504132, and the remainder is 2.8e-08.
