989431 divided by 55 
Our goal is to divide 989431 by 55.

Let's proceed to step 1:
9 divided by 55 is 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 55

Let's proceed to step 2:
When dividing 98 by 55, we get 1 with a remainder of 43.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 55 from 98 leaves us with 43.
Append the next digit (9) from the dividend to 43 and continue with: 439 / 55

Going ahead to step 3:
55 goes into 439 7 times with a remainder of 54.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Deduct 385 from 439 and we're left with 54.
Bring next digit (4) of the dividend behind the 54 and repeat the process: 544 / 55

Moving on to step 4:
The number 55 fits into 544 9 times, leaving a remainder of 49.
Put 9 as the next digit of the answer. 
Result so far: 179.0
Subtract 495 from 544 to get 49.
Include the next digit (3) from the dividend after 49, then repeat: 493 / 55

Advancing to step 5:
When dividing 493 by 55, we get 8 with a remainder of 53.
Write down 8 as next digit of the result. 
Result so far: 1798.0
Subtract 440 from 493 to get 53.
Grab the next digit (1) from the dividend, add it to 53, then carry on: 531 / 55

On to step 6:
531 divided by 55 is 9 with a remainder of 36.
Put 9 as the next digit of the answer. 
Result so far: 17989.0
If we take 495 away from 531, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 7:
360 divided by 55 is 6 with a remainder of 30.
Write down 6 as next digit of the result. 
Result so far: 17989.6
Deduct 330 from 360 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
300 divided by 55 is 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 17989.65
The remainder is 25 after subtracting 275 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 9:
The number 55 fits into 250 4 times, leaving a remainder of 30.
The next digit of our result is 4. 
Result so far: 17989.654
The remainder is 30 after subtracting 220 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 10:
The number 55 fits into 300 5 times, leaving a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 17989.6545
Subtracting 275 from 300 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 11:
55 goes into 250 4 times with a remainder of 30.
The next digit of our result is 4. 
Result so far: 17989.65454
Subtract 220 from 250 to 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.

Step 12:
The number 55 fits into 300 5 times, leaving a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 17989.654545
If we subtract 275 from 300, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 13:
55 can be fit into 250 4 times, resulting in a remainder of 30.
Put 4 as the next digit of the answer. 
Result so far: 17989.6545454
Subtract 220 from 250 to 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.

Moving on to step 14:
300 divided by 55 is 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 17989.65454545
The remainder is 25 after subtracting 275 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final outcome is 17989.65454545, with a leftover of 2.5e-08.
