20974578 ÷ 342 
Our goal is to divide 20974578 by 342.

Step 1:
If we divide 2 by 342, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 342

On to step 2:
If we divide 20 by 342, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Append the next digit (9) from the dividend to 20 and continue with: 209 / 342

Going ahead to step 3:
342 can be fit into 209 0 times, resulting in a remainder of 209.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 209 after subtracting 0 from 209.
Bring next digit (7) of the dividend behind the 209 and repeat the process: 2097 / 342

Let's proceed to step 4:
342 goes into 2097 6 times with a remainder of 45.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 45 after subtracting 2052 from 2097.
Fetch the next digit (4) from the dividend, attach it to 45 and continue: 454 / 342

Advancing to step 5:
454 divided by 342 is 1 with a remainder of 112.
Write down 1 as next digit of the result. 
Result so far: 61.0
The remainder is 112 after subtracting 342 from 454.
Bring next digit (5) of the dividend behind the 112 and repeat the process: 1125 / 342

On to step 6:
When dividing 1125 by 342, we get 3 with a remainder of 99.
Write down 3 as next digit of the result. 
Result so far: 613.0
If we take 1026 away from 1125, we end up with 99.
Include the next digit (7) from the dividend after 99, then repeat: 997 / 342

Advancing to step 7:
If we divide 997 by 342, we get 2 and a remainder of 313.
The number 2 becomes the next digit in our result. 
Result so far: 6132.0
If we take 684 away from 997, we end up with 313.
Include the next digit (8) from the dividend after 313, then repeat: 3138 / 342

Step 8:
342 can be fit into 3138 9 times, resulting in a remainder of 60.
The number 9 becomes the next digit in our result. 
Result so far: 61329.0
If we subtract 3078 from 3138, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 9:
If we divide 600 by 342, we get 1 and a remainder of 258.
Write down 1 as next digit of the result. 
Result so far: 61329.1
If we subtract 342 from 600, we get 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

On to step 10:
342 goes into 2580 7 times with a remainder of 186.
Record the quotient 7 as the next digit in the result. 
Result so far: 61329.17
Subtract 2394 from 2580 to get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Going ahead to step 11:
The number 342 fits into 1860 5 times, leaving a remainder of 150.
The number 5 becomes the next digit in our result. 
Result so far: 61329.175
Deduct 1710 from 1860 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 12:
When dividing 1500 by 342, we get 4 with a remainder of 132.
The next digit of our result is 4. 
Result so far: 61329.1754
Subtract 1368 from 1500 to get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Moving on to step 13:
342 can be fit into 1320 3 times, resulting in a remainder of 294.
Write down 3 as next digit of the result. 
Result so far: 61329.17543
The remainder is 294 after subtracting 1026 from 1320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Moving on to step 14:
When dividing 2940 by 342, we get 8 with a remainder of 204.
The number 8 becomes the next digit in our result. 
Result so far: 61329.175438
If we take 2736 away from 2940, we end up with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Moving on to step 15:
342 can be fit into 2040 5 times, resulting in a remainder of 330.
Use 5 as the next digit of our solution. 
Result so far: 61329.1754385
Deduct 1710 from 2040 and we're left with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Moving on to step 16:
When dividing 3300 by 342, we get 9 with a remainder of 222.
Write down 9 as next digit of the result. 
Result so far: 61329.17543859
Subtracting 3078 from 3300 leaves us with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Our division results in 61329.17543859 with a remaining 2.22e-07.
