71821943 divided by 836 
We want to figure out the number of times 71821943 can be divided by 836.

Moving on to step 1:
836 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 836

Going ahead to step 2:
If we divide 71 by 836, we get 0 and a remainder of 71.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 71 leaves us with 71.
Bring next digit (8) of the dividend behind the 71 and repeat the process: 718 / 836

Moving on to step 3:
836 goes into 718 0 times with a remainder of 718.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 718 to get 718.
Bring next digit (2) of the dividend behind the 718 and repeat the process: 7182 / 836

Step 4:
When dividing 7182 by 836, we get 8 with a remainder of 494.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 6688 from 7182 leaves us with 494.
Take the next digit (1) from the dividend and append it to 494, then repeat: 4941 / 836

On to step 5:
If we divide 4941 by 836, we get 5 and a remainder of 761.
Put 5 as the next digit of the answer. 
Result so far: 85.0
The remainder is 761 after subtracting 4180 from 4941.
Fetch the next digit (9) from the dividend, attach it to 761 and continue: 7619 / 836

Going ahead to step 6:
7619 divided by 836 is 9 with a remainder of 95.
Put 9 as the next digit of the answer. 
Result so far: 859.0
If we take 7524 away from 7619, we end up with 95.
Grab the next digit (4) from the dividend, add it to 95, then carry on: 954 / 836

On to step 7:
The number 836 fits into 954 1 times, leaving a remainder of 118.
Record the quotient 1 as the next digit in the result. 
Result so far: 8591.0
If we take 836 away from 954, we end up with 118.
Bring next digit (3) of the dividend behind the 118 and repeat the process: 1183 / 836

Going ahead to step 8:
The number 836 fits into 1183 1 times, leaving a remainder of 347.
The number 1 becomes the next digit in our result. 
Result so far: 85911.0
Subtracting 836 from 1183 leaves us with 347.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3470, and continue the process.

Going ahead to step 9:
The number 836 fits into 3470 4 times, leaving a remainder of 126.
Put 4 as the next digit of the answer. 
Result so far: 85911.4
If we take 3344 away from 3470, we end up with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Moving on to step 10:
836 can be fit into 1260 1 times, resulting in a remainder of 424.
The next digit of our result is 1. 
Result so far: 85911.41
If we take 836 away from 1260, we end up with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

On to step 11:
If we divide 4240 by 836, we get 5 and a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 85911.415
Subtracting 4180 from 4240 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 12:
When dividing 600 by 836, we get 0 with a remainder of 600.
Use 0 as the next digit of our solution. 
Result so far: 85911.415
The remainder is 600 after subtracting 0 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Let's proceed to step 13:
836 goes into 6000 7 times with a remainder of 148.
Record the quotient 7 as the next digit in the result. 
Result so far: 85911.41507
Subtract 5852 from 6000 to get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

On to step 14:
When dividing 1480 by 836, we get 1 with a remainder of 644.
Record the quotient 1 as the next digit in the result. 
Result so far: 85911.415071
Subtract 836 from 1480 to get 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

Going ahead to step 15:
836 goes into 6440 7 times with a remainder of 588.
Use 7 as the next digit of our solution. 
Result so far: 85911.4150717
If we take 5852 away from 6440, we end up with 588.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

Advancing to step 16:
When dividing 5880 by 836, we get 7 with a remainder of 28.
The number 7 becomes the next digit in our result. 
Result so far: 85911.41507177
Subtract 5852 from 5880 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The quotient of the division is 85911.41507177, and the remainder is 2.8e-08.
