We're dividing 61651529 by 121 
Our goal is to divide 61651529 by 121.

On to step 1:
When dividing 6 by 121, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 121

Advancing to step 2:
61 divided by 121 is 0 with a remainder of 61.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 61, we get 61.
Take the next digit (6) from the dividend and append it to 61, then repeat: 616 / 121

Moving on to step 3:
121 goes into 616 5 times with a remainder of 11.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 605 from 616 and we're left with 11.
Include the next digit (5) from the dividend after 11, then repeat: 115 / 121

On to step 4:
If we divide 115 by 121, we get 0 and a remainder of 115.
The number 0 becomes the next digit in our result. 
Result so far: 50.0
The remainder is 115 after subtracting 0 from 115.
Take the next digit (1) from the dividend and append it to 115, then repeat: 1151 / 121

Advancing to step 5:
The number 121 fits into 1151 9 times, leaving a remainder of 62.
Record the quotient 9 as the next digit in the result. 
Result so far: 509.0
If we subtract 1089 from 1151, we get 62.
Fetch the next digit (5) from the dividend, attach it to 62 and continue: 625 / 121

Moving on to step 6:
When dividing 625 by 121, we get 5 with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 5095.0
Deduct 605 from 625 and we're left with 20.
Take the next digit (2) from the dividend and append it to 20, then repeat: 202 / 121

Advancing to step 7:
202 divided by 121 is 1 with a remainder of 81.
The next digit of our result is 1. 
Result so far: 50951.0
If we take 121 away from 202, we end up with 81.
Append the next digit (9) from the dividend to 81 and continue with: 819 / 121

On to step 8:
121 goes into 819 6 times with a remainder of 93.
Put 6 as the next digit of the answer. 
Result so far: 509516.0
If we take 726 away from 819, we end up with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

On to step 9:
The number 121 fits into 930 7 times, leaving a remainder of 83.
Use 7 as the next digit of our solution. 
Result so far: 509516.7
Deduct 847 from 930 and we're left with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

On to step 10:
The number 121 fits into 830 6 times, leaving a remainder of 104.
Record the quotient 6 as the next digit in the result. 
Result so far: 509516.76
Deduct 726 from 830 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Going ahead to step 11:
The number 121 fits into 1040 8 times, leaving a remainder of 72.
Write down 8 as next digit of the result. 
Result so far: 509516.768
Subtract 968 from 1040 to get 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 12:
If we divide 720 by 121, we get 5 and a remainder of 115.
The next digit of our result is 5. 
Result so far: 509516.7685
The remainder is 115 after subtracting 605 from 720.
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 13:
The number 121 fits into 1150 9 times, leaving a remainder of 61.
The next digit of our result is 9. 
Result so far: 509516.76859
The remainder is 61 after subtracting 1089 from 1150.
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 14:
The number 121 fits into 610 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 509516.768595
Subtract 605 from 610 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 15:
50 divided by 121 is 0 with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 509516.768595
Subtract 0 from 50 to get 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 16:
The number 121 fits into 500 4 times, leaving a remainder of 16.
The next digit of our result is 4. 
Result so far: 509516.76859504
The remainder is 16 after subtracting 484 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

In conclusion, the division gives 509516.76859504 with a balance of 1.6e-08.
