We look at the division of 836139 by 77 
We want to figure out the number of times 836139 can be divided by 77.

Advancing to step 1:
77 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 77

Moving on to step 2:
When dividing 83 by 77, we get 1 with a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 77 from 83, we get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 77

Advancing to step 3:
66 divided by 77 is 0 with a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we subtract 0 from 66, we get 66.
Include the next digit (1) from the dividend after 66, then repeat: 661 / 77

Moving on to step 4:
The number 77 fits into 661 8 times, leaving a remainder of 45.
Write down 8 as next digit of the result. 
Result so far: 108.0
If we subtract 616 from 661, we get 45.
Include the next digit (3) from the dividend after 45, then repeat: 453 / 77

Step 5:
453 divided by 77 is 5 with a remainder of 68.
Record the quotient 5 as the next digit in the result. 
Result so far: 1085.0
The remainder is 68 after subtracting 385 from 453.
Include the next digit (9) from the dividend after 68, then repeat: 689 / 77

Step 6:
77 can be fit into 689 8 times, resulting in a remainder of 73.
Use 8 as the next digit of our solution. 
Result so far: 10858.0
If we take 616 away from 689, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Advancing to step 7:
If we divide 730 by 77, we get 9 and a remainder of 37.
Write down 9 as next digit of the result. 
Result so far: 10858.9
If we subtract 693 from 730, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 8:
370 divided by 77 is 4 with a remainder of 62.
The next digit of our result is 4. 
Result so far: 10858.94
The remainder is 62 after subtracting 308 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 9:
When dividing 620 by 77, we get 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 10858.948
If we subtract 616 from 620, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 10:
40 divided by 77 is 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 10858.948
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
77 goes into 400 5 times with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 10858.94805
Subtract 385 from 400 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 12:
150 divided by 77 is 1 with a remainder of 73.
Write down 1 as next digit of the result. 
Result so far: 10858.948051
If we subtract 77 from 150, we get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 13:
730 divided by 77 is 9 with a remainder of 37.
Write down 9 as next digit of the result. 
Result so far: 10858.9480519
The remainder is 37 after subtracting 693 from 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 14:
77 goes into 370 4 times with a remainder of 62.
The next digit of our result is 4. 
Result so far: 10858.94805194
Subtract 308 from 370 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

The final result is 10858.94805194 with a remainder of 6.2e-08.
