83808620 ÷ 835 
We want to figure out the number of times 83808620 can be divided by 835.

Step 1:
835 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 835

On to step 2:
83 divided by 835 is 0 with a remainder of 83.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 83 leaves us with 83.
Bring next digit (8) of the dividend behind the 83 and repeat the process: 838 / 835

On to step 3:
835 goes into 838 1 times with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 3 after subtracting 835 from 838.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 835

On to step 4:
30 divided by 835 is 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 10.0
Deduct 0 from 30 and we're left with 30.
Bring next digit (8) of the dividend behind the 30 and repeat the process: 308 / 835

Let's proceed to step 5:
308 divided by 835 is 0 with a remainder of 308.
Use 0 as the next digit of our solution. 
Result so far: 100.0
If we subtract 0 from 308, we get 308.
Bring next digit (6) of the dividend behind the 308 and repeat the process: 3086 / 835

Let's proceed to step 6:
The number 835 fits into 3086 3 times, leaving a remainder of 581.
Use 3 as the next digit of our solution. 
Result so far: 1003.0
Subtract 2505 from 3086 to get 581.
Bring next digit (2) of the dividend behind the 581 and repeat the process: 5812 / 835

Going ahead to step 7:
835 can be fit into 5812 6 times, resulting in a remainder of 802.
Put 6 as the next digit of the answer. 
Result so far: 10036.0
Subtracting 5010 from 5812 leaves us with 802.
Take the next digit (0) from the dividend and append it to 802, then repeat: 8020 / 835

Moving on to step 8:
When dividing 8020 by 835, we get 9 with a remainder of 505.
Use 9 as the next digit of our solution. 
Result so far: 100369.0
If we take 7515 away from 8020, we end up with 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Let's proceed to step 9:
835 goes into 5050 6 times with a remainder of 40.
Put 6 as the next digit of the answer. 
Result so far: 100369.6
Subtract 5010 from 5050 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.

Step 10:
If we divide 400 by 835, we get 0 and a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 100369.6
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Step 11:
835 goes into 4000 4 times with a remainder of 660.
The next digit of our result is 4. 
Result so far: 100369.604
Subtract 3340 from 4000 to get 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Advancing to step 12:
835 can be fit into 6600 7 times, resulting in a remainder of 755.
The number 7 becomes the next digit in our result. 
Result so far: 100369.6047
If we subtract 5845 from 6600, we get 755.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7550, and continue the process.

Advancing to step 13:
The number 835 fits into 7550 9 times, leaving a remainder of 35.
Write down 9 as next digit of the result. 
Result so far: 100369.60479
Subtract 7515 from 7550 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 14:
350 divided by 835 is 0 with a remainder of 350.
Record the quotient 0 as the next digit in the result. 
Result so far: 100369.60479
Subtract 0 from 350 to get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Advancing to step 15:
835 goes into 3500 4 times with a remainder of 160.
Put 4 as the next digit of the answer. 
Result so far: 100369.6047904
If we take 3340 away from 3500, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 16:
835 goes into 1600 1 times with a remainder of 765.
Record the quotient 1 as the next digit in the result. 
Result so far: 100369.60479041
Subtracting 835 from 1600 leaves us with 765.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7650, and continue the process.

The final result is 100369.60479041 with a remainder of 7.65e-07.
