Let's divide 858874 by 77
Let's see how many times 77 fits into 858874.

On to step 1:
When dividing 8 by 77, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 77

On to step 2:
The number 77 fits into 85 1 times, leaving a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 77 from 85 and we're left with 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 77

Going ahead to step 3:
When dividing 88 by 77, we get 1 with a remainder of 11.
The next digit of our result is 1. 
Result so far: 11.0
If we take 77 away from 88, we end up with 11.
Append the next digit (8) from the dividend to 11 and continue with: 118 / 77

Moving on to step 4:
The number 77 fits into 118 1 times, leaving a remainder of 41.
The next digit of our result is 1. 
Result so far: 111.0
If we subtract 77 from 118, we get 41.
Take the next digit (7) from the dividend and append it to 41, then repeat: 417 / 77

Moving on to step 5:
77 can be fit into 417 5 times, resulting in a remainder of 32.
The number 5 becomes the next digit in our result. 
Result so far: 1115.0
If we subtract 385 from 417, we get 32.
Take the next digit (4) from the dividend and append it to 32, then repeat: 324 / 77

Moving on to step 6:
77 goes into 324 4 times with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 11154.0
The remainder is 16 after subtracting 308 from 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 7:
When dividing 160 by 77, we get 2 with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 11154.2
If we take 154 away from 160, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 8:
If we divide 60 by 77, we get 0 and a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 11154.2
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 9:
The number 77 fits into 600 7 times, leaving a remainder of 61.
Use 7 as the next digit of our solution. 
Result so far: 11154.207
If we take 539 away from 600, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 10:
77 can be fit into 610 7 times, resulting in a remainder of 71.
Use 7 as the next digit of our solution. 
Result so far: 11154.2077
If we take 539 away from 610, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

The quotient of the division is 11154.2077, and the remainder is 0.00071.
