68251557 ÷ 121 
Our goal is to divide 68251557 by 121.

Let's proceed to step 1:
6 divided by 121 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 121

Going ahead to step 2:
121 can be fit into 68 0 times, resulting in a remainder of 68.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 68 after subtracting 0 from 68.
Append the next digit (2) from the dividend to 68 and continue with: 682 / 121

Step 3:
682 divided by 121 is 5 with a remainder of 77.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 605 from 682 and we're left with 77.
Grab the next digit (5) from the dividend, add it to 77, then carry on: 775 / 121

Going ahead to step 4:
121 can be fit into 775 6 times, resulting in a remainder of 49.
Use 6 as the next digit of our solution. 
Result so far: 56.0
The remainder is 49 after subtracting 726 from 775.
Take the next digit (1) from the dividend and append it to 49, then repeat: 491 / 121

Moving on to step 5:
121 can be fit into 491 4 times, resulting in a remainder of 7.
Put 4 as the next digit of the answer. 
Result so far: 564.0
Subtract 484 from 491 to get 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 121

Going ahead to step 6:
75 divided by 121 is 0 with a remainder of 75.
The number 0 becomes the next digit in our result. 
Result so far: 5640.0
Subtracting 0 from 75 leaves us with 75.
Append the next digit (5) from the dividend to 75 and continue with: 755 / 121

Step 7:
When dividing 755 by 121, we get 6 with a remainder of 29.
Put 6 as the next digit of the answer. 
Result so far: 56406.0
If we subtract 726 from 755, we get 29.
Bring next digit (7) of the dividend behind the 29 and repeat the process: 297 / 121

Moving on to step 8:
When dividing 297 by 121, we get 2 with a remainder of 55.
The next digit of our result is 2. 
Result so far: 564062.0
Deduct 242 from 297 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 9:
The number 121 fits into 550 4 times, leaving a remainder of 66.
The next digit of our result is 4. 
Result so far: 564062.4
If we take 484 away from 550, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 10:
If we divide 660 by 121, we get 5 and a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 564062.45
Subtracting 605 from 660 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 11:
121 goes into 550 4 times with a remainder of 66.
The next digit of our result is 4. 
Result so far: 564062.454
If we subtract 484 from 550, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 12:
121 can be fit into 660 5 times, resulting in a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 564062.4545
Deduct 605 from 660 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 13:
121 can be fit into 550 4 times, resulting in a remainder of 66.
The next digit of our result is 4. 
Result so far: 564062.45454
Subtracting 484 from 550 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 14:
If we divide 660 by 121, we get 5 and a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 564062.454545
Subtract 605 from 660 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 15:
The number 121 fits into 550 4 times, leaving a remainder of 66.
Put 4 as the next digit of the answer. 
Result so far: 564062.4545454
The remainder is 66 after subtracting 484 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 16:
When dividing 660 by 121, we get 5 with a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 564062.45454545
Subtracting 605 from 660 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

The quotient of the division is 564062.45454545, and the remainder is 5.5e-08.
