We're dividing 21879311 by 340 
Our goal is to divide 21879311 by 340.

Step 1:
340 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 340

Let's proceed to step 2:
340 goes into 21 0 times with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Grab the next digit (8) from the dividend, add it to 21, then carry on: 218 / 340

On to step 3:
If we divide 218 by 340, we get 0 and a remainder of 218.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 218, we end up with 218.
Append the next digit (7) from the dividend to 218 and continue with: 2187 / 340

Let's proceed to step 4:
If we divide 2187 by 340, we get 6 and a remainder of 147.
Write down 6 as next digit of the result. 
Result so far: 6.0
Deduct 2040 from 2187 and we're left with 147.
Include the next digit (9) from the dividend after 147, then repeat: 1479 / 340

Advancing to step 5:
1479 divided by 340 is 4 with a remainder of 119.
The next digit of our result is 4. 
Result so far: 64.0
Deduct 1360 from 1479 and we're left with 119.
Bring next digit (3) of the dividend behind the 119 and repeat the process: 1193 / 340

Let's proceed to step 6:
340 can be fit into 1193 3 times, resulting in a remainder of 173.
Record the quotient 3 as the next digit in the result. 
Result so far: 643.0
If we take 1020 away from 1193, we end up with 173.
Grab the next digit (1) from the dividend, add it to 173, then carry on: 1731 / 340

Let's proceed to step 7:
The number 340 fits into 1731 5 times, leaving a remainder of 31.
The next digit of our result is 5. 
Result so far: 6435.0
If we take 1700 away from 1731, we end up with 31.
Append the next digit (1) from the dividend to 31 and continue with: 311 / 340

Advancing to step 8:
When dividing 311 by 340, we get 0 with a remainder of 311.
The next digit of our result is 0. 
Result so far: 64350.0
Deduct 0 from 311 and we're left with 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Advancing to step 9:
340 can be fit into 3110 9 times, resulting in a remainder of 50.
Write down 9 as next digit of the result. 
Result so far: 64350.9
Subtracting 3060 from 3110 leaves us with 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 10:
When dividing 500 by 340, we get 1 with a remainder of 160.
Use 1 as the next digit of our solution. 
Result so far: 64350.91
The remainder is 160 after subtracting 340 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 11:
340 can be fit into 1600 4 times, resulting in a remainder of 240.
The next digit of our result is 4. 
Result so far: 64350.914
Deduct 1360 from 1600 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 12:
2400 divided by 340 is 7 with a remainder of 20.
Write down 7 as next digit of the result. 
Result so far: 64350.9147
If we subtract 2380 from 2400, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 13:
340 can be fit into 200 0 times, resulting in a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 64350.9147
Subtracting 0 from 200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 14:
If we divide 2000 by 340, we get 5 and a remainder of 300.
The next digit of our result is 5. 
Result so far: 64350.914705
Subtract 1700 from 2000 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 15:
If we divide 3000 by 340, we get 8 and a remainder of 280.
Record the quotient 8 as the next digit in the result. 
Result so far: 64350.9147058
The remainder is 280 after subtracting 2720 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 16:
When dividing 2800 by 340, we get 8 with a remainder of 80.
Write down 8 as next digit of the result. 
Result so far: 64350.91470588
If we subtract 2720 from 2800, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Our division results in 64350.91470588 with a remaining 8e-08.
