We look at the division of 20212602 by 342 
Let's see how many times 342 fits into 20212602.

Going ahead to step 1:
342 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 342

On to step 2:
The number 342 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Append the next digit (2) from the dividend to 20 and continue with: 202 / 342

Moving on to step 3:
202 divided by 342 is 0 with a remainder of 202.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 202, we end up with 202.
Fetch the next digit (1) from the dividend, attach it to 202 and continue: 2021 / 342

Step 4:
If we divide 2021 by 342, we get 5 and a remainder of 311.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 1710 from 2021 to get 311.
Take the next digit (2) from the dividend and append it to 311, then repeat: 3112 / 342

Let's proceed to step 5:
When dividing 3112 by 342, we get 9 with a remainder of 34.
The number 9 becomes the next digit in our result. 
Result so far: 59.0
Subtract 3078 from 3112 to get 34.
Bring next digit (6) of the dividend behind the 34 and repeat the process: 346 / 342

Moving on to step 6:
The number 342 fits into 346 1 times, leaving a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 591.0
Subtracting 342 from 346 leaves us with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 342

Going ahead to step 7:
If we divide 40 by 342, we get 0 and a remainder of 40.
The next digit of our result is 0. 
Result so far: 5910.0
Subtract 0 from 40 to get 40.
Grab the next digit (2) from the dividend, add it to 40, then carry on: 402 / 342

On to step 8:
342 can be fit into 402 1 times, resulting in a remainder of 60.
The next digit of our result is 1. 
Result so far: 59101.0
If we subtract 342 from 402, 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.

Let's proceed to step 9:
600 divided by 342 is 1 with a remainder of 258.
Record the quotient 1 as the next digit in the result. 
Result so far: 59101.1
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.

Moving on to step 10:
The number 342 fits into 2580 7 times, leaving a remainder of 186.
The next digit of our result is 7. 
Result so far: 59101.17
Deduct 2394 from 2580 and we're left with 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:
342 can be fit into 1860 5 times, resulting in a remainder of 150.
Write down 5 as next digit of the result. 
Result so far: 59101.175
The remainder is 150 after subtracting 1710 from 1860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 12:
342 goes into 1500 4 times with a remainder of 132.
Put 4 as the next digit of the answer. 
Result so far: 59101.1754
Subtracting 1368 from 1500 leaves us with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Step 13:
The number 342 fits into 1320 3 times, leaving a remainder of 294.
Put 3 as the next digit of the answer. 
Result so far: 59101.17543
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.

Going ahead to step 14:
If we divide 2940 by 342, we get 8 and a remainder of 204.
Use 8 as the next digit of our solution. 
Result so far: 59101.175438
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.

Advancing to step 15:
When dividing 2040 by 342, we get 5 with a remainder of 330.
Put 5 as the next digit of the answer. 
Result so far: 59101.1754385
Subtract 1710 from 2040 to get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Step 16:
When dividing 3300 by 342, we get 9 with a remainder of 222.
The number 9 becomes the next digit in our result. 
Result so far: 59101.17543859
The remainder is 222 after subtracting 3078 from 3300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

The quotient of the division is 59101.17543859, and the remainder is 2.22e-07.
