We look at the division of 55087183 by 77 
We're looking to find how many times 77 goes into 55087183.

Going ahead to step 1:
5 divided by 77 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 77

Let's proceed to step 2:
If we divide 55 by 77, we get 0 and a remainder of 55.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 55 after subtracting 0 from 55.
Bring next digit (0) of the dividend behind the 55 and repeat the process: 550 / 77

Let's proceed to step 3:
77 goes into 550 7 times with a remainder of 11.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 11 after subtracting 539 from 550.
Include the next digit (8) from the dividend after 11, then repeat: 118 / 77

On to step 4:
77 goes into 118 1 times with a remainder of 41.
Put 1 as the next digit of the answer. 
Result so far: 71.0
Deduct 77 from 118 and we're left with 41.
Append the next digit (7) from the dividend to 41 and continue with: 417 / 77

Moving on to step 5:
If we divide 417 by 77, we get 5 and a remainder of 32.
Use 5 as the next digit of our solution. 
Result so far: 715.0
Subtract 385 from 417 to get 32.
Take the next digit (1) from the dividend and append it to 32, then repeat: 321 / 77

Going ahead to step 6:
The number 77 fits into 321 4 times, leaving a remainder of 13.
Record the quotient 4 as the next digit in the result. 
Result so far: 7154.0
If we subtract 308 from 321, we get 13.
Grab the next digit (8) from the dividend, add it to 13, then carry on: 138 / 77

On to step 7:
When dividing 138 by 77, we get 1 with a remainder of 61.
Use 1 as the next digit of our solution. 
Result so far: 71541.0
Subtracting 77 from 138 leaves us with 61.
Bring next digit (3) of the dividend behind the 61 and repeat the process: 613 / 77

On to step 8:
77 goes into 613 7 times with a remainder of 74.
The next digit of our result is 7. 
Result so far: 715417.0
If we subtract 539 from 613, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 9:
77 can be fit into 740 9 times, resulting in a remainder of 47.
Use 9 as the next digit of our solution. 
Result so far: 715417.9
Subtract 693 from 740 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 10:
If we divide 470 by 77, we get 6 and a remainder of 8.
The next digit of our result is 6. 
Result so far: 715417.96
Subtract 462 from 470 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 11:
77 goes into 80 1 times with a remainder of 3.
The next digit of our result is 1. 
Result so far: 715417.961
Subtracting 77 from 80 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 12:
If we divide 30 by 77, we get 0 and a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 715417.961
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 13:
The number 77 fits into 300 3 times, leaving a remainder of 69.
Put 3 as the next digit of the answer. 
Result so far: 715417.96103
If we subtract 231 from 300, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 14:
When dividing 690 by 77, we get 8 with a remainder of 74.
Put 8 as the next digit of the answer. 
Result so far: 715417.961038
If we subtract 616 from 690, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 15:
740 divided by 77 is 9 with a remainder of 47.
Use 9 as the next digit of our solution. 
Result so far: 715417.9610389
Deduct 693 from 740 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 16:
The number 77 fits into 470 6 times, leaving a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 715417.96103896
If we take 462 away from 470, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 715417.96103896 and a remainder of 8e-09.
