We look at the division of 42122060 by 686 
We want to divide 42122060 by 686.

Moving on to step 1:
The number 686 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 686

Step 2:
When dividing 42 by 686, we get 0 with a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Include the next digit (1) from the dividend after 42, then repeat: 421 / 686

On to step 3:
686 can be fit into 421 0 times, resulting in a remainder of 421.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 421 leaves us with 421.
Include the next digit (2) from the dividend after 421, then repeat: 4212 / 686

Going ahead to step 4:
If we divide 4212 by 686, we get 6 and a remainder of 96.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we subtract 4116 from 4212, we get 96.
Append the next digit (2) from the dividend to 96 and continue with: 962 / 686

Step 5:
The number 686 fits into 962 1 times, leaving a remainder of 276.
Use 1 as the next digit of our solution. 
Result so far: 61.0
The remainder is 276 after subtracting 686 from 962.
Fetch the next digit (0) from the dividend, attach it to 276 and continue: 2760 / 686

Moving on to step 6:
When dividing 2760 by 686, we get 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 614.0
If we subtract 2744 from 2760, we get 16.
Append the next digit (6) from the dividend to 16 and continue with: 166 / 686

Step 7:
When dividing 166 by 686, we get 0 with a remainder of 166.
Record the quotient 0 as the next digit in the result. 
Result so far: 6140.0
If we take 0 away from 166, we end up with 166.
Grab the next digit (0) from the dividend, add it to 166, then carry on: 1660 / 686

On to step 8:
If we divide 1660 by 686, we get 2 and a remainder of 288.
The number 2 becomes the next digit in our result. 
Result so far: 61402.0
If we take 1372 away from 1660, we end up with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Moving on to step 9:
686 goes into 2880 4 times with a remainder of 136.
The next digit of our result is 4. 
Result so far: 61402.4
Subtract 2744 from 2880 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Step 10:
686 goes into 1360 1 times with a remainder of 674.
Write down 1 as next digit of the result. 
Result so far: 61402.41
The remainder is 674 after subtracting 686 from 1360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6740, and continue the process.

Advancing to step 11:
686 can be fit into 6740 9 times, resulting in a remainder of 566.
The number 9 becomes the next digit in our result. 
Result so far: 61402.419
Subtract 6174 from 6740 to get 566.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

Moving on to step 12:
When dividing 5660 by 686, we get 8 with a remainder of 172.
Put 8 as the next digit of the answer. 
Result so far: 61402.4198
Subtract 5488 from 5660 to get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Moving on to step 13:
If we divide 1720 by 686, we get 2 and a remainder of 348.
Put 2 as the next digit of the answer. 
Result so far: 61402.41982
If we take 1372 away from 1720, we end up with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Going ahead to step 14:
If we divide 3480 by 686, we get 5 and a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 61402.419825
If we subtract 3430 from 3480, we 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.

Let's proceed to step 15:
When dividing 500 by 686, we get 0 with a remainder of 500.
The number 0 becomes the next digit in our result. 
Result so far: 61402.419825
Subtract 0 from 500 to get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Going ahead to step 16:
The number 686 fits into 5000 7 times, leaving a remainder of 198.
Put 7 as the next digit of the answer. 
Result so far: 61402.41982507
Subtract 4802 from 5000 to get 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

The quotient of the division is 61402.41982507, and the remainder is 1.98e-07.
