We look at the division of 68121251 by 557 
Let's see how many times 557 fits into 68121251.

Advancing to step 1:
557 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 557

Step 2:
If we divide 68 by 557, we get 0 and a remainder of 68.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 68, we end up with 68.
Bring next digit (1) of the dividend behind the 68 and repeat the process: 681 / 557

On to step 3:
If we divide 681 by 557, we get 1 and a remainder of 124.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 557 from 681 to get 124.
Grab the next digit (2) from the dividend, add it to 124, then carry on: 1242 / 557

Advancing to step 4:
557 can be fit into 1242 2 times, resulting in a remainder of 128.
The next digit of our result is 2. 
Result so far: 12.0
The remainder is 128 after subtracting 1114 from 1242.
Take the next digit (1) from the dividend and append it to 128, then repeat: 1281 / 557

Let's proceed to step 5:
If we divide 1281 by 557, we get 2 and a remainder of 167.
Use 2 as the next digit of our solution. 
Result so far: 122.0
If we subtract 1114 from 1281, we get 167.
Bring next digit (2) of the dividend behind the 167 and repeat the process: 1672 / 557

On to step 6:
If we divide 1672 by 557, we get 3 and a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 1223.0
If we take 1671 away from 1672, we end up with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 557

On to step 7:
The number 557 fits into 15 0 times, leaving a remainder of 15.
The next digit of our result is 0. 
Result so far: 12230.0
Subtracting 0 from 15 leaves us with 15.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 557

Moving on to step 8:
If we divide 151 by 557, we get 0 and a remainder of 151.
Use 0 as the next digit of our solution. 
Result so far: 122300.0
Subtract 0 from 151 to get 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Moving on to step 9:
The number 557 fits into 1510 2 times, leaving a remainder of 396.
Write down 2 as next digit of the result. 
Result so far: 122300.2
Deduct 1114 from 1510 and we're left with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Let's proceed to step 10:
If we divide 3960 by 557, we get 7 and a remainder of 61.
Write down 7 as next digit of the result. 
Result so far: 122300.27
The remainder is 61 after subtracting 3899 from 3960.
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 557 is 1 with a remainder of 53.
Put 1 as the next digit of the answer. 
Result so far: 122300.271
Deduct 557 from 610 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 12:
When dividing 530 by 557, we get 0 with a remainder of 530.
Write down 0 as next digit of the result. 
Result so far: 122300.271
If we take 0 away from 530, we end up with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Going ahead to step 13:
When dividing 5300 by 557, we get 9 with a remainder of 287.
The number 9 becomes the next digit in our result. 
Result so far: 122300.27109
Subtracting 5013 from 5300 leaves us with 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

Going ahead to step 14:
When dividing 2870 by 557, we get 5 with a remainder of 85.
Use 5 as the next digit of our solution. 
Result so far: 122300.271095
Subtract 2785 from 2870 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 15:
850 divided by 557 is 1 with a remainder of 293.
The number 1 becomes the next digit in our result. 
Result so far: 122300.2710951
The remainder is 293 after subtracting 557 from 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

Advancing to step 16:
557 goes into 2930 5 times with a remainder of 145.
The next digit of our result is 5. 
Result so far: 122300.27109515
If we take 2785 away from 2930, we end up with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

The final result is 122300.27109515 with a remainder of 1.45e-07.
