421710 ÷ 34 
We want to divide 421710 by 34.

Let's proceed to step 1:
The number 34 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 34

Going ahead to step 2:
42 divided by 34 is 1 with a remainder of 8.
The next digit of our result is 1. 
Result so far: 1.0
If we take 34 away from 42, we end up with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 34

Going ahead to step 3:
34 can be fit into 81 2 times, resulting in a remainder of 13.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we subtract 68 from 81, we get 13.
Grab the next digit (7) from the dividend, add it to 13, then carry on: 137 / 34

Step 4:
The number 34 fits into 137 4 times, leaving a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 124.0
Subtract 136 from 137 to get 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 34

Advancing to step 5:
34 goes into 11 0 times with a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 1240.0
Subtract 0 from 11 to get 11.
Bring next digit (0) of the dividend behind the 11 and repeat the process: 110 / 34

Moving on to step 6:
34 goes into 110 3 times with a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 12403.0
If we subtract 102 from 110, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 7:
34 can be fit into 80 2 times, resulting in a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 12403.2
If we subtract 68 from 80, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 8:
If we divide 120 by 34, we get 3 and a remainder of 18.
Put 3 as the next digit of the answer. 
Result so far: 12403.23
Subtracting 102 from 120 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 9:
The number 34 fits into 180 5 times, leaving a remainder of 10.
The next digit of our result is 5. 
Result so far: 12403.235
Subtracting 170 from 180 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
100 divided by 34 is 2 with a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 12403.2352
Deduct 68 from 100 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 11:
320 divided by 34 is 9 with a remainder of 14.
The number 9 becomes the next digit in our result. 
Result so far: 12403.23529
If we take 306 away from 320, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 12:
34 goes into 140 4 times with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 12403.235294
If we subtract 136 from 140, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 13:
34 can be fit into 40 1 times, resulting in a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 12403.2352941
Subtract 34 from 40 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 14:
If we divide 60 by 34, we get 1 and a remainder of 26.
Use 1 as the next digit of our solution. 
Result so far: 12403.23529411
Subtract 34 from 60 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Our division results in 12403.23529411 with a remaining 2.6e-08.
