79009836 ÷ 391 
We want to figure out the number of times 79009836 can be divided by 391.

Let's proceed to step 1:
391 can be fit into 7 0 times, resulting in 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.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 391

Advancing to step 2:
391 goes into 79 0 times with a remainder of 79.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 79, we end up with 79.
Fetch the next digit (0) from the dividend, attach it to 79 and continue: 790 / 391

On to step 3:
If we divide 790 by 391, we get 2 and a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 782 from 790 leaves us with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 391

On to step 4:
391 can be fit into 80 0 times, resulting in a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 20.0
The remainder is 80 after subtracting 0 from 80.
Include the next digit (9) from the dividend after 80, then repeat: 809 / 391

Let's proceed to step 5:
If we divide 809 by 391, we get 2 and a remainder of 27.
The next digit of our result is 2. 
Result so far: 202.0
Subtract 782 from 809 to get 27.
Bring next digit (8) of the dividend behind the 27 and repeat the process: 278 / 391

Step 6:
391 goes into 278 0 times with a remainder of 278.
The next digit of our result is 0. 
Result so far: 2020.0
Deduct 0 from 278 and we're left with 278.
Include the next digit (3) from the dividend after 278, then repeat: 2783 / 391

Step 7:
If we divide 2783 by 391, we get 7 and a remainder of 46.
The number 7 becomes the next digit in our result. 
Result so far: 20207.0
The remainder is 46 after subtracting 2737 from 2783.
Fetch the next digit (6) from the dividend, attach it to 46 and continue: 466 / 391

Let's proceed to step 8:
When dividing 466 by 391, we get 1 with a remainder of 75.
Write down 1 as next digit of the result. 
Result so far: 202071.0
If we take 391 away from 466, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 9:
750 divided by 391 is 1 with a remainder of 359.
Put 1 as the next digit of the answer. 
Result so far: 202071.1
The remainder is 359 after subtracting 391 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

Advancing to step 10:
When dividing 3590 by 391, we get 9 with a remainder of 71.
The number 9 becomes the next digit in our result. 
Result so far: 202071.19
The remainder is 71 after subtracting 3519 from 3590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Step 11:
If we divide 710 by 391, we get 1 and a remainder of 319.
Put 1 as the next digit of the answer. 
Result so far: 202071.191
Deduct 391 from 710 and we're left with 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

On to step 12:
The number 391 fits into 3190 8 times, leaving a remainder of 62.
Record the quotient 8 as the next digit in the result. 
Result so far: 202071.1918
The remainder is 62 after subtracting 3128 from 3190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 13:
When dividing 620 by 391, we get 1 with a remainder of 229.
The number 1 becomes the next digit in our result. 
Result so far: 202071.19181
Subtract 391 from 620 to get 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Advancing to step 14:
If we divide 2290 by 391, we get 5 and a remainder of 335.
Use 5 as the next digit of our solution. 
Result so far: 202071.191815
Subtract 1955 from 2290 to get 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Advancing to step 15:
3350 divided by 391 is 8 with a remainder of 222.
Put 8 as the next digit of the answer. 
Result so far: 202071.1918158
If we take 3128 away from 3350, we end up with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Moving on to step 16:
391 can be fit into 2220 5 times, resulting in a remainder of 265.
Write down 5 as next digit of the result. 
Result so far: 202071.19181585
Deduct 1955 from 2220 and we're left with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

The quotient of the division is 202071.19181585, and the remainder is 2.65e-07.
