If we subtract 0 from 5, we get 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 121

Moving on to step 2:
121 goes into 57 0 times with a remainder of 57.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 57, we get 57.
Take the next digit (5) from the dividend and append it to 57, then repeat: 575 / 121

Going ahead to step 3:
When dividing 575 by 121, we get 4 with a remainder of 91.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 484 away from 575, we end up with 91.

Let's proceed to step 4:
919 divided by 121 is 7 with a remainder of 72.
The number 7 becomes the next digit in our result. 
Result so far: 47.0
Subtracting 847 from 919 leaves us with 72.
Include the next digit (1) from the dividend after 72, then repeat: 721 / 121

Advancing to step 5:
When dividing 721 by 121, we get 5 with a remainder of 116.
Record the quotient 5 as the next digit in the result. 
Result so far: 475.0
Subtracting 605 from 721 leaves us with 116.
Grab the next digit (6) from the dividend, add it to 116, then carry on: 1166 / 121

On to step 6:
The number 121 fits into 1166 9 times, leaving a remainder of 77.
The next digit of our result is 9. 
Result so far: 4759.0
If we subtract 1089 from 1166, we get 77.
Take the next digit (8) from the dividend and append it to 77, then repeat: 778 / 121

Step 7:
When dividing 778 by 121, we get 6 with a remainder of 52.
The number 6 becomes the next digit in our result. 
Result so far: 47596.0
Subtracting 726 from 778 leaves us with 52.
Include the next digit (8) from the dividend after 52, then repeat: 528 / 121

On to step 8:
When dividing 528 by 121, we get 4 with a remainder of 44.
Write down 4 as next digit of the result. 
Result so far: 475964.0
Subtract 484 from 528 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 9:
440 divided by 121 is 3 with a remainder of 77.
The next digit of our result is 3. 
Result so far: 475964.3
If we subtract 363 from 440, we get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

On to step 10:
When dividing 770 by 121, we get 6 with a remainder of 44.
The next digit of our result is 6. 
Result so far: 475964.36
Subtracting 726 from 770 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 11:
If we divide 440 by 121, we get 3 and a remainder of 77.
Write down 3 as next digit of the result. 
Result so far: 475964.363
If we subtract 363 from 440, we get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 12:
The number 121 fits into 770 6 times, leaving a remainder of 44.
The next digit of our result is 6. 
Result so far: 475964.3636
If we take 726 away from 770, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 13:
When dividing 440 by 121, we get 3 with a remainder of 77.
Write down 3 as next digit of the result. 
Result so far: 475964.36363
Subtracting 363 from 440 leaves us with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 14:
770 divided by 121 is 6 with a remainder of 44.
The next digit of our result is 6. 
Result so far: 475964.363636
Subtracting 726 from 770 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 15:
440 divided by 121 is 3 with a remainder of 77.
Write down 3 as next digit of the result. 
Result so far: 475964.3636363
If we subtract 363 from 440, we get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Advancing to step 16:
121 goes into 770 6 times with a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 475964.36363636
Deduct 726 from 770 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Our division results in 475964.36363636 with a remaining 4.4e-08.
