6 divided by 121 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 121

On to step 2:
The number 121 fits into 60 0 times, leaving a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 60 after subtracting 0 from 60.
Append the next digit (8) from the dividend to 60 and continue with: 608 / 121

Step 3:
When dividing 608 by 121, we get 5 with a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 3 after subtracting 605 from 608.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 121

Let's proceed to step 4:
When dividing 38 by 121, we get 0 with a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 50.0
The remainder is 38 after subtracting 0 from 38.
Append the next digit (1) from the dividend to 38 and continue with: 381 / 121

Going ahead to step 5:
121 can be fit into 381 3 times, resulting in a remainder of 18.
Use 3 as the next digit of our solution. 
Result so far: 503.0
If we take 363 away from 381, we end up with 18.
Take the next digit (0) from the dividend and append it to 18, then repeat: 180 / 121

Let's proceed to step 6:
When dividing 180 by 121, we get 1 with a remainder of 59.
Put 1 as the next digit of the answer. 
Result so far: 5031.0
The remainder is 59 after subtracting 121 from 180.
Take the next digit (6) from the dividend and append it to 59, then repeat: 596 / 121

Moving on to step 7:
The number 121 fits into 596 4 times, leaving a remainder of 112.
The number 4 becomes the next digit in our result. 
Result so far: 50314.0
The remainder is 112 after subtracting 484 from 596.
Fetch the next digit (6) from the dividend, attach it to 112 and continue: 1126 / 121

Advancing to step 8:
121 goes into 1126 9 times with a remainder of 37.
Write down 9 as next digit of the result. 
Result so far: 503149.0
If we subtract 1089 from 1126, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 9:
When dividing 370 by 121, we get 3 with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 503149.3
Subtract 363 from 370 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 10:
121 goes into 70 0 times with a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 503149.3
Deduct 0 from 70 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 11:
When dividing 700 by 121, we get 5 with a remainder of 95.
The next digit of our result is 5. 
Result so far: 503149.305
The remainder is 95 after subtracting 605 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Moving on to step 12:
950 divided by 121 is 7 with a remainder of 103.
Put 7 as the next digit of the answer. 
Result so far: 503149.3057
If we subtract 847 from 950, we get 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Moving on to step 13:
If we divide 1030 by 121, we get 8 and a remainder of 62.
The number 8 becomes the next digit in our result. 
Result so far: 503149.30578
Deduct 968 from 1030 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 14:
When dividing 620 by 121, we get 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 503149.305785
The remainder is 15 after subtracting 605 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 15:
If we divide 150 by 121, we get 1 and a remainder of 29.
The next digit of our result is 1. 
Result so far: 503149.3057851
Deduct 121 from 150 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 16:
When dividing 290 by 121, we get 2 with a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 503149.30578512
Subtract 242 from 290 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final outcome is 503149.30578512, with a leftover of 4.8e-08.
