We're dividing 549158 by 77 
We want to divide 549158 by 77.

Moving on to step 1:
77 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 77

Let's proceed to step 2:
The number 77 fits into 54 0 times, leaving a remainder of 54.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 54, we get 54.
Append the next digit (9) from the dividend to 54 and continue with: 549 / 77

Moving on to step 3:
The number 77 fits into 549 7 times, leaving a remainder of 10.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 10 after subtracting 539 from 549.
Bring next digit (1) of the dividend behind the 10 and repeat the process: 101 / 77

Let's proceed to step 4:
The number 77 fits into 101 1 times, leaving a remainder of 24.
The number 1 becomes the next digit in our result. 
Result so far: 71.0
The remainder is 24 after subtracting 77 from 101.
Bring next digit (5) of the dividend behind the 24 and repeat the process: 245 / 77

Let's proceed to step 5:
77 can be fit into 245 3 times, resulting in a remainder of 14.
Write down 3 as next digit of the result. 
Result so far: 713.0
Subtract 231 from 245 to get 14.
Grab the next digit (8) from the dividend, add it to 14, then carry on: 148 / 77

Step 6:
When dividing 148 by 77, we get 1 with a remainder of 71.
Put 1 as the next digit of the answer. 
Result so far: 7131.0
Deduct 77 from 148 and we're left 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.

Advancing to step 7:
When dividing 710 by 77, we get 9 with a remainder of 17.
Use 9 as the next digit of our solution. 
Result so far: 7131.9
Subtract 693 from 710 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 8:
When dividing 170 by 77, we get 2 with a remainder of 16.
The next digit of our result is 2. 
Result so far: 7131.92
Deduct 154 from 170 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 9:
When dividing 160 by 77, we get 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 7131.922
The remainder is 6 after subtracting 154 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final outcome is 7131.922, with a leftover of 0.0006.
