We're dividing 66703872 by 840 
We're looking to find how many times 840 goes into 66703872.

On to step 1:
840 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 840

Going ahead to step 2:
840 can be fit into 66 0 times, resulting in a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Bring next digit (7) of the dividend behind the 66 and repeat the process: 667 / 840

Moving on to step 3:
840 can be fit into 667 0 times, resulting in a remainder of 667.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 667, we end up with 667.
Include the next digit (0) from the dividend after 667, then repeat: 6670 / 840

Moving on to step 4:
When dividing 6670 by 840, we get 7 with a remainder of 790.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 5880 from 6670 and we're left with 790.
Bring next digit (3) of the dividend behind the 790 and repeat the process: 7903 / 840

Advancing to step 5:
7903 divided by 840 is 9 with a remainder of 343.
Write down 9 as next digit of the result. 
Result so far: 79.0
If we take 7560 away from 7903, we end up with 343.
Bring next digit (8) of the dividend behind the 343 and repeat the process: 3438 / 840

Step 6:
When dividing 3438 by 840, we get 4 with a remainder of 78.
Record the quotient 4 as the next digit in the result. 
Result so far: 794.0
If we take 3360 away from 3438, we end up with 78.
Include the next digit (7) from the dividend after 78, then repeat: 787 / 840

Moving on to step 7:
787 divided by 840 is 0 with a remainder of 787.
Write down 0 as next digit of the result. 
Result so far: 7940.0
Deduct 0 from 787 and we're left with 787.
Grab the next digit (2) from the dividend, add it to 787, then carry on: 7872 / 840

Let's proceed to step 8:
The number 840 fits into 7872 9 times, leaving a remainder of 312.
The number 9 becomes the next digit in our result. 
Result so far: 79409.0
Subtract 7560 from 7872 to get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Advancing to step 9:
If we divide 3120 by 840, we get 3 and a remainder of 600.
The number 3 becomes the next digit in our result. 
Result so far: 79409.3
If we subtract 2520 from 3120, 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.

Going ahead to step 10:
840 goes into 6000 7 times with a remainder of 120.
The number 7 becomes the next digit in our result. 
Result so far: 79409.37
Subtracting 5880 from 6000 leaves us 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.

Advancing to step 11:
1200 divided by 840 is 1 with a remainder of 360.
Put 1 as the next digit of the answer. 
Result so far: 79409.371
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.

Step 12:
840 can be fit into 3600 4 times, resulting in a remainder of 240.
Use 4 as the next digit of our solution. 
Result so far: 79409.3714
Deduct 3360 from 3600 and we're left 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.

Going ahead to step 13:
The number 840 fits into 2400 2 times, leaving a remainder of 720.
Write down 2 as next digit of the result. 
Result so far: 79409.37142
Deduct 1680 from 2400 and we're left with 720.
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 14:
840 goes into 7200 8 times with a remainder of 480.
The next digit of our result is 8. 
Result so far: 79409.371428
Subtracting 6720 from 7200 leaves us 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.

Advancing to step 15:
840 goes into 4800 5 times with a remainder of 600.
Put 5 as the next digit of the answer. 
Result so far: 79409.3714285
If we take 4200 away from 4800, we end up with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

On to step 16:
840 goes into 6000 7 times with a remainder of 120.
The next digit of our result is 7. 
Result so far: 79409.37142857
Subtracting 5880 from 6000 leaves us 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.

Our division results in 79409.37142857 with a remaining 1.2e-07.
