We look at the division of 77957859 by 843 
We want to figure out the number of times 77957859 can be divided by 843.

On to step 1:
843 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 843

Let's proceed to step 2:
843 goes into 77 0 times with a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Fetch the next digit (9) from the dividend, attach it to 77 and continue: 779 / 843

Advancing to step 3:
843 can be fit into 779 0 times, resulting in a remainder of 779.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 779, we end up with 779.
Append the next digit (5) from the dividend to 779 and continue with: 7795 / 843

Step 4:
The number 843 fits into 7795 9 times, leaving a remainder of 208.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
The remainder is 208 after subtracting 7587 from 7795.
Include the next digit (7) from the dividend after 208, then repeat: 2087 / 843

Step 5:
If we divide 2087 by 843, we get 2 and a remainder of 401.
Put 2 as the next digit of the answer. 
Result so far: 92.0
Deduct 1686 from 2087 and we're left with 401.
Take the next digit (8) from the dividend and append it to 401, then repeat: 4018 / 843

Step 6:
If we divide 4018 by 843, we get 4 and a remainder of 646.
Put 4 as the next digit of the answer. 
Result so far: 924.0
Deduct 3372 from 4018 and we're left with 646.
Append the next digit (5) from the dividend to 646 and continue with: 6465 / 843

Step 7:
843 can be fit into 6465 7 times, resulting in a remainder of 564.
Use 7 as the next digit of our solution. 
Result so far: 9247.0
The remainder is 564 after subtracting 5901 from 6465.
Fetch the next digit (9) from the dividend, attach it to 564 and continue: 5649 / 843

Let's proceed to step 8:
843 can be fit into 5649 6 times, resulting in a remainder of 591.
Write down 6 as next digit of the result. 
Result so far: 92476.0
Subtracting 5058 from 5649 leaves us with 591.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5910, and continue the process.

Step 9:
When dividing 5910 by 843, we get 7 with a remainder of 9.
The next digit of our result is 7. 
Result so far: 92476.7
Subtract 5901 from 5910 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 10:
90 divided by 843 is 0 with a remainder of 90.
The next digit of our result is 0. 
Result so far: 92476.7
If we subtract 0 from 90, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 11:
If we divide 900 by 843, we get 1 and a remainder of 57.
Use 1 as the next digit of our solution. 
Result so far: 92476.701
If we take 843 away from 900, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 12:
570 divided by 843 is 0 with a remainder of 570.
The number 0 becomes the next digit in our result. 
Result so far: 92476.701
Subtract 0 from 570 to get 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Advancing to step 13:
If we divide 5700 by 843, we get 6 and a remainder of 642.
Write down 6 as next digit of the result. 
Result so far: 92476.70106
Deduct 5058 from 5700 and we're left with 642.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6420, and continue the process.

Let's proceed to step 14:
The number 843 fits into 6420 7 times, leaving a remainder of 519.
The number 7 becomes the next digit in our result. 
Result so far: 92476.701067
Deduct 5901 from 6420 and we're left with 519.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5190, and continue the process.

Moving on to step 15:
843 goes into 5190 6 times with a remainder of 132.
Record the quotient 6 as the next digit in the result. 
Result so far: 92476.7010676
Subtract 5058 from 5190 to get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Step 16:
843 can be fit into 1320 1 times, resulting in a remainder of 477.
The next digit of our result is 1. 
Result so far: 92476.70106761
If we take 843 away from 1320, we end up with 477.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4770, and continue the process.

After the division, we end up with 92476.70106761 and a remainder of 4.77e-07.
