Let's divide 21347687 by 234
We want to figure out the number of times 21347687 can be divided by 234.

Going ahead to step 1:
When dividing 2 by 234, we get 0 with 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 (1) of the dividend behind the 2 and repeat the process: 21 / 234

Let's proceed to step 2:
If we divide 21 by 234, we get 0 and a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Bring next digit (3) of the dividend behind the 21 and repeat the process: 213 / 234

Step 3:
The number 234 fits into 213 0 times, leaving a remainder of 213.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 213 to get 213.
Bring next digit (4) of the dividend behind the 213 and repeat the process: 2134 / 234

Going ahead to step 4:
The number 234 fits into 2134 9 times, leaving a remainder of 28.
The next digit of our result is 9. 
Result so far: 9.0
Subtracting 2106 from 2134 leaves us with 28.
Fetch the next digit (7) from the dividend, attach it to 28 and continue: 287 / 234

Going ahead to step 5:
If we divide 287 by 234, we get 1 and a remainder of 53.
Put 1 as the next digit of the answer. 
Result so far: 91.0
Subtracting 234 from 287 leaves us with 53.
Include the next digit (6) from the dividend after 53, then repeat: 536 / 234

Step 6:
If we divide 536 by 234, we get 2 and a remainder of 68.
The number 2 becomes the next digit in our result. 
Result so far: 912.0
Deduct 468 from 536 and we're left with 68.
Take the next digit (8) from the dividend and append it to 68, then repeat: 688 / 234

Advancing to step 7:
If we divide 688 by 234, we get 2 and a remainder of 220.
Write down 2 as next digit of the result. 
Result so far: 9122.0
Deduct 468 from 688 and we're left with 220.
Grab the next digit (7) from the dividend, add it to 220, then carry on: 2207 / 234

Going ahead to step 8:
The number 234 fits into 2207 9 times, leaving a remainder of 101.
The next digit of our result is 9. 
Result so far: 91229.0
Subtracting 2106 from 2207 leaves us with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Step 9:
The number 234 fits into 1010 4 times, leaving a remainder of 74.
The next digit of our result is 4. 
Result so far: 91229.4
Subtract 936 from 1010 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 10:
740 divided by 234 is 3 with a remainder of 38.
Record the quotient 3 as the next digit in the result. 
Result so far: 91229.43
If we subtract 702 from 740, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 11:
If we divide 380 by 234, we get 1 and a remainder of 146.
The number 1 becomes the next digit in our result. 
Result so far: 91229.431
If we subtract 234 from 380, we get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Moving on to step 12:
234 goes into 1460 6 times with a remainder of 56.
Use 6 as the next digit of our solution. 
Result so far: 91229.4316
If we take 1404 away from 1460, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 13:
560 divided by 234 is 2 with a remainder of 92.
Write down 2 as next digit of the result. 
Result so far: 91229.43162
If we subtract 468 from 560, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Moving on to step 14:
920 divided by 234 is 3 with a remainder of 218.
Record the quotient 3 as the next digit in the result. 
Result so far: 91229.431623
If we subtract 702 from 920, we get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Moving on to step 15:
234 goes into 2180 9 times with a remainder of 74.
Write down 9 as next digit of the result. 
Result so far: 91229.4316239
If we take 2106 away from 2180, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 16:
234 can be fit into 740 3 times, resulting in a remainder of 38.
Put 3 as the next digit of the answer. 
Result so far: 91229.43162393
The remainder is 38 after subtracting 702 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The final outcome is 91229.43162393, with a leftover of 3.8e-08.
