Let's divide 1287455 by 842
We want to divide 1287455 by 842.

Let's proceed to step 1:
842 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 842

Going ahead to step 2:
12 divided by 842 is 0 with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Bring next digit (8) of the dividend behind the 12 and repeat the process: 128 / 842

Moving on to step 3:
842 can be fit into 128 0 times, resulting in a remainder of 128.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 128, we get 128.
Take the next digit (7) from the dividend and append it to 128, then repeat: 1287 / 842

Step 4:
1287 divided by 842 is 1 with a remainder of 445.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 842 from 1287 to get 445.
Bring next digit (4) of the dividend behind the 445 and repeat the process: 4454 / 842

On to step 5:
842 goes into 4454 5 times with a remainder of 244.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtract 4210 from 4454 to get 244.
Grab the next digit (5) from the dividend, add it to 244, then carry on: 2445 / 842

Going ahead to step 6:
When dividing 2445 by 842, we get 2 with a remainder of 761.
The number 2 becomes the next digit in our result. 
Result so far: 152.0
Deduct 1684 from 2445 and we're left with 761.
Grab the next digit (5) from the dividend, add it to 761, then carry on: 7615 / 842

Let's proceed to step 7:
7615 divided by 842 is 9 with a remainder of 37.
The number 9 becomes the next digit in our result. 
Result so far: 1529.0
Subtract 7578 from 7615 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 8:
370 divided by 842 is 0 with a remainder of 370.
Record the quotient 0 as the next digit in the result. 
Result so far: 1529.0
If we subtract 0 from 370, we get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Step 9:
The number 842 fits into 3700 4 times, leaving a remainder of 332.
The number 4 becomes the next digit in our result. 
Result so far: 1529.04
Deduct 3368 from 3700 and we're left with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

On to step 10:
3320 divided by 842 is 3 with a remainder of 794.
The number 3 becomes the next digit in our result. 
Result so far: 1529.043
Subtracting 2526 from 3320 leaves us with 794.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7940, and continue the process.

Moving on to step 11:
842 can be fit into 7940 9 times, resulting in a remainder of 362.
Record the quotient 9 as the next digit in the result. 
Result so far: 1529.0439
If we subtract 7578 from 7940, we get 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Step 12:
If we divide 3620 by 842, we get 4 and a remainder of 252.
Record the quotient 4 as the next digit in the result. 
Result so far: 1529.04394
The remainder is 252 after subtracting 3368 from 3620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Moving on to step 13:
842 goes into 2520 2 times with a remainder of 836.
Put 2 as the next digit of the answer. 
Result so far: 1529.043942
If we subtract 1684 from 2520, we get 836.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8360, and continue the process.

On to step 14:
When dividing 8360 by 842, we get 9 with a remainder of 782.
The number 9 becomes the next digit in our result. 
Result so far: 1529.0439429
If we subtract 7578 from 8360, we get 782.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7820, and continue the process.

Advancing to step 15:
7820 divided by 842 is 9 with a remainder of 242.
The next digit of our result is 9. 
Result so far: 1529.04394299
The remainder is 242 after subtracting 7578 from 7820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

The quotient of the division is 1529.04394299, and the remainder is 2.42e-07.
