30439845 ÷ 840 
We're looking to find how many times 840 goes into 30439845.

Moving on to step 1:
840 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 840

Moving on to step 2:
The number 840 fits into 30 0 times, leaving a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Append the next digit (4) from the dividend to 30 and continue with: 304 / 840

Advancing to step 3:
If we divide 304 by 840, we get 0 and a remainder of 304.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 304 to get 304.
Take the next digit (3) from the dividend and append it to 304, then repeat: 3043 / 840

Moving on to step 4:
The number 840 fits into 3043 3 times, leaving a remainder of 523.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 2520 from 3043, we get 523.
Grab the next digit (9) from the dividend, add it to 523, then carry on: 5239 / 840

Step 5:
The number 840 fits into 5239 6 times, leaving a remainder of 199.
Use 6 as the next digit of our solution. 
Result so far: 36.0
The remainder is 199 after subtracting 5040 from 5239.
Bring next digit (8) of the dividend behind the 199 and repeat the process: 1998 / 840

On to step 6:
1998 divided by 840 is 2 with a remainder of 318.
Use 2 as the next digit of our solution. 
Result so far: 362.0
Deduct 1680 from 1998 and we're left with 318.
Grab the next digit (4) from the dividend, add it to 318, then carry on: 3184 / 840

Going ahead to step 7:
840 can be fit into 3184 3 times, resulting in a remainder of 664.
Record the quotient 3 as the next digit in the result. 
Result so far: 3623.0
The remainder is 664 after subtracting 2520 from 3184.
Fetch the next digit (5) from the dividend, attach it to 664 and continue: 6645 / 840

Advancing to step 8:
If we divide 6645 by 840, we get 7 and a remainder of 765.
Write down 7 as next digit of the result. 
Result so far: 36237.0
The remainder is 765 after subtracting 5880 from 6645.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7650, and continue the process.

Going ahead to step 9:
When dividing 7650 by 840, we get 9 with a remainder of 90.
Write down 9 as next digit of the result. 
Result so far: 36237.9
If we take 7560 away from 7650, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 10:
840 goes into 900 1 times with a remainder of 60.
The number 1 becomes the next digit in our result. 
Result so far: 36237.91
The remainder is 60 after subtracting 840 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 11:
When dividing 600 by 840, we get 0 with a remainder of 600.
Write down 0 as next digit of the result. 
Result so far: 36237.91
If we subtract 0 from 600, we get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Advancing to step 12:
When dividing 6000 by 840, we get 7 with a remainder of 120.
Put 7 as the next digit of the answer. 
Result so far: 36237.9107
Deduct 5880 from 6000 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 13:
1200 divided by 840 is 1 with a remainder of 360.
The number 1 becomes the next digit in our result. 
Result so far: 36237.91071
If we subtract 840 from 1200, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Moving on to step 14:
The number 840 fits into 3600 4 times, leaving a remainder of 240.
Record the quotient 4 as the next digit in the result. 
Result so far: 36237.910714
Subtracting 3360 from 3600 leaves us 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.

On to step 15:
If we divide 2400 by 840, we get 2 and a remainder of 720.
Record the quotient 2 as the next digit in the result. 
Result so far: 36237.9107142
The remainder is 720 after subtracting 1680 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Let's proceed to step 16:
840 goes into 7200 8 times with a remainder of 480.
Put 8 as the next digit of the answer. 
Result so far: 36237.91071428
If we take 6720 away from 7200, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

The final result is 36237.91071428 with a remainder of 4.8e-07.
