862121 ÷ 55 
We want to figure out the number of times 862121 can be divided by 55.

Step 1:
The number 55 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 55

On to step 2:
86 divided by 55 is 1 with a remainder of 31.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 55 from 86 and we're left with 31.
Include the next digit (2) from the dividend after 31, then repeat: 312 / 55

Step 3:
If we divide 312 by 55, we get 5 and a remainder of 37.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we take 275 away from 312, we end up with 37.
Fetch the next digit (1) from the dividend, attach it to 37 and continue: 371 / 55

Moving on to step 4:
If we divide 371 by 55, we get 6 and a remainder of 41.
Write down 6 as next digit of the result. 
Result so far: 156.0
If we take 330 away from 371, we end up with 41.
Append the next digit (2) from the dividend to 41 and continue with: 412 / 55

Let's proceed to step 5:
412 divided by 55 is 7 with a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 1567.0
Subtracting 385 from 412 leaves us with 27.
Fetch the next digit (1) from the dividend, attach it to 27 and continue: 271 / 55

Going ahead to step 6:
The number 55 fits into 271 4 times, leaving a remainder of 51.
Record the quotient 4 as the next digit in the result. 
Result so far: 15674.0
Subtract 220 from 271 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 7:
The number 55 fits into 510 9 times, leaving a remainder of 15.
The number 9 becomes the next digit in our result. 
Result so far: 15674.9
If we take 495 away from 510, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 8:
The number 55 fits into 150 2 times, leaving a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 15674.92
Subtracting 110 from 150 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 9:
If we divide 400 by 55, we get 7 and a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 15674.927
Subtracting 385 from 400 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 10:
When dividing 150 by 55, we get 2 with a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 15674.9272
The remainder is 40 after subtracting 110 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 11:
55 goes into 400 7 times with a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 15674.92727
Deduct 385 from 400 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 12:
The number 55 fits into 150 2 times, leaving a remainder of 40.
The next digit of our result is 2. 
Result so far: 15674.927272
If we subtract 110 from 150, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 13:
The number 55 fits into 400 7 times, leaving a remainder of 15.
The number 7 becomes the next digit in our result. 
Result so far: 15674.9272727
If we subtract 385 from 400, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 14:
55 can be fit into 150 2 times, resulting in a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 15674.92727272
Subtracting 110 from 150 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final result is 15674.92727272 with a remainder of 4e-08.
