We're dividing 851392 by 55 
We want to figure out the number of times 851392 can be divided by 55.

Going ahead to step 1:
55 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 55

Step 2:
85 divided by 55 is 1 with a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 55 away from 85, we end up with 30.
Include the next digit (1) from the dividend after 30, then repeat: 301 / 55

Going ahead to step 3:
55 can be fit into 301 5 times, resulting in a remainder of 26.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtracting 275 from 301 leaves us with 26.
Take the next digit (3) from the dividend and append it to 26, then repeat: 263 / 55

Moving on to step 4:
When dividing 263 by 55, we get 4 with a remainder of 43.
The next digit of our result is 4. 
Result so far: 154.0
Deduct 220 from 263 and we're left with 43.
Bring next digit (9) of the dividend behind the 43 and repeat the process: 439 / 55

Advancing to step 5:
55 can be fit into 439 7 times, resulting in a remainder of 54.
Use 7 as the next digit of our solution. 
Result so far: 1547.0
If we subtract 385 from 439, we get 54.
Grab the next digit (2) from the dividend, add it to 54, then carry on: 542 / 55

Advancing to step 6:
The number 55 fits into 542 9 times, leaving a remainder of 47.
Write down 9 as next digit of the result. 
Result so far: 15479.0
Deduct 495 from 542 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.

On to step 7:
470 divided by 55 is 8 with a remainder of 30.
Put 8 as the next digit of the answer. 
Result so far: 15479.8
Deduct 440 from 470 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.

Going ahead to step 8:
55 can be fit into 300 5 times, resulting in a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 15479.85
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.

On to step 9:
When dividing 250 by 55, we get 4 with a remainder of 30.
The number 4 becomes the next digit in our result. 
Result so far: 15479.854
Subtracting 220 from 250 leaves us 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.

Advancing to step 10:
If we divide 300 by 55, we get 5 and a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 15479.8545
Subtract 275 from 300 to 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.

On to step 11:
If we divide 250 by 55, we get 4 and a remainder of 30.
Put 4 as the next digit of the answer. 
Result so far: 15479.85454
Deduct 220 from 250 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.

Advancing to step 12:
If we divide 300 by 55, we get 5 and a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 15479.854545
Deduct 275 from 300 and we're left 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.

Step 13:
The number 55 fits into 250 4 times, leaving a remainder of 30.
The next digit of our result is 4. 
Result so far: 15479.8545454
Deduct 220 from 250 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.

Step 14:
If we divide 300 by 55, we get 5 and a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 15479.85454545
Deduct 275 from 300 and we're left 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.

The quotient of the division is 15479.85454545, and the remainder is 2.5e-08.
