71873963 ÷ 835 
Our goal is to divide 71873963 by 835.

Moving on to step 1:
If we divide 7 by 835, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 835

Let's proceed to step 2:
835 goes into 71 0 times with a remainder of 71.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 71, we end up with 71.
Include the next digit (8) from the dividend after 71, then repeat: 718 / 835

Moving on to step 3:
718 divided by 835 is 0 with a remainder of 718.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 718, we end up with 718.
Grab the next digit (7) from the dividend, add it to 718, then carry on: 7187 / 835

Moving on to step 4:
The number 835 fits into 7187 8 times, leaving a remainder of 507.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 6680 from 7187 to get 507.
Fetch the next digit (3) from the dividend, attach it to 507 and continue: 5073 / 835

Moving on to step 5:
When dividing 5073 by 835, we get 6 with a remainder of 63.
Record the quotient 6 as the next digit in the result. 
Result so far: 86.0
Subtracting 5010 from 5073 leaves us with 63.
Include the next digit (9) from the dividend after 63, then repeat: 639 / 835

Going ahead to step 6:
When dividing 639 by 835, we get 0 with a remainder of 639.
The number 0 becomes the next digit in our result. 
Result so far: 860.0
If we take 0 away from 639, we end up with 639.
Take the next digit (6) from the dividend and append it to 639, then repeat: 6396 / 835

Moving on to step 7:
When dividing 6396 by 835, we get 7 with a remainder of 551.
Use 7 as the next digit of our solution. 
Result so far: 8607.0
The remainder is 551 after subtracting 5845 from 6396.
Bring next digit (3) of the dividend behind the 551 and repeat the process: 5513 / 835

Advancing to step 8:
5513 divided by 835 is 6 with a remainder of 503.
Record the quotient 6 as the next digit in the result. 
Result so far: 86076.0
If we take 5010 away from 5513, we end up with 503.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5030, and continue the process.

Going ahead to step 9:
If we divide 5030 by 835, we get 6 and a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 86076.6
Deduct 5010 from 5030 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 10:
200 divided by 835 is 0 with a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 86076.6
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 11:
The number 835 fits into 2000 2 times, leaving a remainder of 330.
The number 2 becomes the next digit in our result. 
Result so far: 86076.602
If we take 1670 away from 2000, we end up with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Moving on to step 12:
When dividing 3300 by 835, we get 3 with a remainder of 795.
Use 3 as the next digit of our solution. 
Result so far: 86076.6023
The remainder is 795 after subtracting 2505 from 3300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7950, and continue the process.

Let's proceed to step 13:
When dividing 7950 by 835, we get 9 with a remainder of 435.
Put 9 as the next digit of the answer. 
Result so far: 86076.60239
The remainder is 435 after subtracting 7515 from 7950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

Moving on to step 14:
4350 divided by 835 is 5 with a remainder of 175.
Write down 5 as next digit of the result. 
Result so far: 86076.602395
Deduct 4175 from 4350 and we're left with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Advancing to step 15:
If we divide 1750 by 835, we get 2 and a remainder of 80.
The number 2 becomes the next digit in our result. 
Result so far: 86076.6023952
Subtracting 1670 from 1750 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 16:
835 goes into 800 0 times with a remainder of 800.
The next digit of our result is 0. 
Result so far: 86076.6023952
If we subtract 0 from 800, we get 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

The final outcome is 86076.6023952, with a leftover of 8e-07.
