Let's divide 67310290 by 840
We're looking to find how many times 840 goes into 67310290.

Let's proceed to step 1:
840 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 840

Let's proceed to step 2:
67 divided by 840 is 0 with a remainder of 67.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 67 and we're left with 67.
Take the next digit (3) from the dividend and append it to 67, then repeat: 673 / 840

Advancing to step 3:
840 goes into 673 0 times with a remainder of 673.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 673, we end up with 673.
Grab the next digit (1) from the dividend, add it to 673, then carry on: 6731 / 840

Going ahead to step 4:
If we divide 6731 by 840, we get 8 and a remainder of 11.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 6720 from 6731 and we're left with 11.
Grab the next digit (0) from the dividend, add it to 11, then carry on: 110 / 840

On to step 5:
840 can be fit into 110 0 times, resulting in a remainder of 110.
Record the quotient 0 as the next digit in the result. 
Result so far: 80.0
If we take 0 away from 110, we end up with 110.
Grab the next digit (2) from the dividend, add it to 110, then carry on: 1102 / 840

On to step 6:
1102 divided by 840 is 1 with a remainder of 262.
Record the quotient 1 as the next digit in the result. 
Result so far: 801.0
If we subtract 840 from 1102, we get 262.
Include the next digit (9) from the dividend after 262, then repeat: 2629 / 840

Step 7:
When dividing 2629 by 840, we get 3 with a remainder of 109.
Put 3 as the next digit of the answer. 
Result so far: 8013.0
Deduct 2520 from 2629 and we're left with 109.
Bring next digit (0) of the dividend behind the 109 and repeat the process: 1090 / 840

On to step 8:
If we divide 1090 by 840, we get 1 and a remainder of 250.
The number 1 becomes the next digit in our result. 
Result so far: 80131.0
If we subtract 840 from 1090, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Step 9:
If we divide 2500 by 840, we get 2 and a remainder of 820.
The next digit of our result is 2. 
Result so far: 80131.2
The remainder is 820 after subtracting 1680 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8200, and continue the process.

Going ahead to step 10:
840 goes into 8200 9 times with a remainder of 640.
The number 9 becomes the next digit in our result. 
Result so far: 80131.29
If we subtract 7560 from 8200, we get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Let's proceed to step 11:
6400 divided by 840 is 7 with a remainder of 520.
Write down 7 as next digit of the result. 
Result so far: 80131.297
Deduct 5880 from 6400 and we're left with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Moving on to step 12:
840 goes into 5200 6 times with a remainder of 160.
Write down 6 as next digit of the result. 
Result so far: 80131.2976
If we subtract 5040 from 5200, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 13:
If we divide 1600 by 840, we get 1 and a remainder of 760.
Record the quotient 1 as the next digit in the result. 
Result so far: 80131.29761
The remainder is 760 after subtracting 840 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Moving on to step 14:
When dividing 7600 by 840, we get 9 with a remainder of 40.
Use 9 as the next digit of our solution. 
Result so far: 80131.297619
Subtract 7560 from 7600 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 15:
The number 840 fits into 400 0 times, leaving a remainder of 400.
The next digit of our result is 0. 
Result so far: 80131.297619
Subtract 0 from 400 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Moving on to step 16:
The number 840 fits into 4000 4 times, leaving a remainder of 640.
Write down 4 as next digit of the result. 
Result so far: 80131.29761904
If we take 3360 away from 4000, we end up with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

In conclusion, the division gives 80131.29761904 with a balance of 6.4e-07.
