We divide 21234260 by 159
We want to figure out the number of times 21234260 can be divided by 159.

Going ahead to step 1:
When dividing 2 by 159, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 159

Let's proceed to step 2:
When dividing 21 by 159, we get 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Append the next digit (2) from the dividend to 21 and continue with: 212 / 159

Moving on to step 3:
159 can be fit into 212 1 times, resulting in a remainder of 53.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 159 from 212 leaves us with 53.
Grab the next digit (3) from the dividend, add it to 53, then carry on: 533 / 159

Going ahead to step 4:
533 divided by 159 is 3 with a remainder of 56.
The next digit of our result is 3. 
Result so far: 13.0
Deduct 477 from 533 and we're left with 56.
Bring next digit (4) of the dividend behind the 56 and repeat the process: 564 / 159

On to step 5:
564 divided by 159 is 3 with a remainder of 87.
Put 3 as the next digit of the answer. 
Result so far: 133.0
The remainder is 87 after subtracting 477 from 564.
Append the next digit (2) from the dividend to 87 and continue with: 872 / 159

Advancing to step 6:
The number 159 fits into 872 5 times, leaving a remainder of 77.
Write down 5 as next digit of the result. 
Result so far: 1335.0
If we subtract 795 from 872, we get 77.
Grab the next digit (6) from the dividend, add it to 77, then carry on: 776 / 159

Moving on to step 7:
When dividing 776 by 159, we get 4 with a remainder of 140.
Use 4 as the next digit of our solution. 
Result so far: 13354.0
If we subtract 636 from 776, we get 140.
Grab the next digit (0) from the dividend, add it to 140, then carry on: 1400 / 159

Going ahead to step 8:
1400 divided by 159 is 8 with a remainder of 128.
The number 8 becomes the next digit in our result. 
Result so far: 133548.0
Deduct 1272 from 1400 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Advancing to step 9:
When dividing 1280 by 159, we get 8 with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 133548.8
If we take 1272 away from 1280, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
When dividing 80 by 159, we get 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 133548.8
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 11:
The number 159 fits into 800 5 times, leaving a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 133548.805
The remainder is 5 after subtracting 795 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 12:
159 goes into 50 0 times with a remainder of 50.
The next digit of our result is 0. 
Result so far: 133548.805
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 13:
When dividing 500 by 159, we get 3 with a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 133548.80503
The remainder is 23 after subtracting 477 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 14:
If we divide 230 by 159, we get 1 and a remainder of 71.
Use 1 as the next digit of our solution. 
Result so far: 133548.805031
The remainder is 71 after subtracting 159 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Step 15:
710 divided by 159 is 4 with a remainder of 74.
The number 4 becomes the next digit in our result. 
Result so far: 133548.8050314
Deduct 636 from 710 and we're left 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:
The number 159 fits into 740 4 times, leaving a remainder of 104.
Record the quotient 4 as the next digit in the result. 
Result so far: 133548.80503144
Deduct 636 from 740 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

In conclusion, the division gives 133548.80503144 with a balance of 1.04e-07.
