We look at the division of 71419998 by 840 
We want to figure out the number of times 71419998 can be divided by 840.

On to step 1:
When dividing 7 by 840, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 840

Moving on to step 2:
840 goes into 71 0 times with a remainder of 71.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 71 to get 71.
Fetch the next digit (4) from the dividend, attach it to 71 and continue: 714 / 840

On to step 3:
If we divide 714 by 840, we get 0 and a remainder of 714.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 714 and we're left with 714.
Take the next digit (1) from the dividend and append it to 714, then repeat: 7141 / 840

Step 4:
The number 840 fits into 7141 8 times, leaving a remainder of 421.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 6720 from 7141, we get 421.
Grab the next digit (9) from the dividend, add it to 421, then carry on: 4219 / 840

Advancing to step 5:
840 can be fit into 4219 5 times, resulting in a remainder of 19.
The next digit of our result is 5. 
Result so far: 85.0
If we subtract 4200 from 4219, we get 19.
Take the next digit (9) from the dividend and append it to 19, then repeat: 199 / 840

Let's proceed to step 6:
840 goes into 199 0 times with a remainder of 199.
The number 0 becomes the next digit in our result. 
Result so far: 850.0
If we take 0 away from 199, we end up with 199.
Include the next digit (9) from the dividend after 199, then repeat: 1999 / 840

Moving on to step 7:
840 goes into 1999 2 times with a remainder of 319.
Record the quotient 2 as the next digit in the result. 
Result so far: 8502.0
If we subtract 1680 from 1999, we get 319.
Append the next digit (8) from the dividend to 319 and continue with: 3198 / 840

Going ahead to step 8:
The number 840 fits into 3198 3 times, leaving a remainder of 678.
Use 3 as the next digit of our solution. 
Result so far: 85023.0
Subtracting 2520 from 3198 leaves us with 678.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6780, and continue the process.

Going ahead to step 9:
6780 divided by 840 is 8 with a remainder of 60.
The next digit of our result is 8. 
Result so far: 85023.8
If we subtract 6720 from 6780, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 10:
When dividing 600 by 840, we get 0 with a remainder of 600.
Put 0 as the next digit of the answer. 
Result so far: 85023.8
Deduct 0 from 600 and we're left 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.

Step 11:
When dividing 6000 by 840, we get 7 with a remainder of 120.
The number 7 becomes the next digit in our result. 
Result so far: 85023.807
The remainder is 120 after subtracting 5880 from 6000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 12:
1200 divided by 840 is 1 with a remainder of 360.
Record the quotient 1 as the next digit in the result. 
Result so far: 85023.8071
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.

On to step 13:
If we divide 3600 by 840, we get 4 and a remainder of 240.
Use 4 as the next digit of our solution. 
Result so far: 85023.80714
The remainder is 240 after subtracting 3360 from 3600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 14:
840 can be fit into 2400 2 times, resulting in a remainder of 720.
Use 2 as the next digit of our solution. 
Result so far: 85023.807142
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.

Going ahead to step 15:
The number 840 fits into 7200 8 times, leaving a remainder of 480.
The number 8 becomes the next digit in our result. 
Result so far: 85023.8071428
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 16:
4800 divided by 840 is 5 with a remainder of 600.
Write down 5 as next digit of the result. 
Result so far: 85023.80714285
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.

The final outcome is 85023.80714285, with a leftover of 6e-07.
