We're dividing 77210 by 55 
Let's see how many times 55 fits into 77210.

Step 1:
55 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 55

Moving on to step 2:
55 goes into 77 1 times with a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 55 from 77 to get 22.
Append the next digit (2) from the dividend to 22 and continue with: 222 / 55

On to step 3:
When dividing 222 by 55, we get 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we take 220 away from 222, we end up with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 55

On to step 4:
If we divide 21 by 55, we get 0 and a remainder of 21.
The next digit of our result is 0. 
Result so far: 140.0
Deduct 0 from 21 and we're left with 21.
Fetch the next digit (0) from the dividend, attach it to 21 and continue: 210 / 55

Going ahead to step 5:
The number 55 fits into 210 3 times, leaving a remainder of 45.
Put 3 as the next digit of the answer. 
Result so far: 1403.0
If we subtract 165 from 210, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 6:
The number 55 fits into 450 8 times, leaving a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 1403.8
If we subtract 440 from 450, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
If we divide 100 by 55, we get 1 and a remainder of 45.
Write down 1 as next digit of the result. 
Result so far: 1403.81
Subtract 55 from 100 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 8:
If we divide 450 by 55, we get 8 and a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 1403.818
Subtracting 440 from 450 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
55 goes into 100 1 times with a remainder of 45.
The next digit of our result is 1. 
Result so far: 1403.8181
Subtract 55 from 100 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 10:
The number 55 fits into 450 8 times, leaving a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 1403.81818
The remainder is 10 after subtracting 440 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 11:
When dividing 100 by 55, we get 1 with a remainder of 45.
The next digit of our result is 1. 
Result so far: 1403.818181
If we take 55 away from 100, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 12:
When dividing 450 by 55, we get 8 with a remainder of 10.
The next digit of our result is 8. 
Result so far: 1403.8181818
If we subtract 440 from 450, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 13:
If we divide 100 by 55, we get 1 and a remainder of 45.
Record the quotient 1 as the next digit in the result. 
Result so far: 1403.81818181
The remainder is 45 after subtracting 55 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The final outcome is 1403.81818181, with a leftover of 4.5e-08.
