We're dividing 851222 by 54 
Let's see how many times 54 fits into 851222.

Going ahead to step 1:
If we divide 8 by 54, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 54

Let's proceed to step 2:
The number 54 fits into 85 1 times, leaving a remainder of 31.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 54 from 85 and we're left with 31.
Include the next digit (1) from the dividend after 31, then repeat: 311 / 54

On to step 3:
If we divide 311 by 54, we get 5 and a remainder of 41.
Write down 5 as next digit of the result. 
Result so far: 15.0
The remainder is 41 after subtracting 270 from 311.
Grab the next digit (2) from the dividend, add it to 41, then carry on: 412 / 54

Moving on to step 4:
When dividing 412 by 54, we get 7 with a remainder of 34.
Put 7 as the next digit of the answer. 
Result so far: 157.0
Deduct 378 from 412 and we're left with 34.
Grab the next digit (2) from the dividend, add it to 34, then carry on: 342 / 54

Advancing to step 5:
The number 54 fits into 342 6 times, leaving a remainder of 18.
Write down 6 as next digit of the result. 
Result so far: 1576.0
If we take 324 away from 342, we end up with 18.
Include the next digit (2) from the dividend after 18, then repeat: 182 / 54

Moving on to step 6:
54 goes into 182 3 times with a remainder of 20.
The number 3 becomes the next digit in our result. 
Result so far: 15763.0
Subtracting 162 from 182 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 7:
The number 54 fits into 200 3 times, leaving a remainder of 38.
Put 3 as the next digit of the answer. 
Result so far: 15763.3
Subtract 162 from 200 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 8:
The number 54 fits into 380 7 times, leaving a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 15763.37
Deduct 378 from 380 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 9:
If we divide 20 by 54, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 15763.37
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 10:
If we divide 200 by 54, we get 3 and a remainder of 38.
Record the quotient 3 as the next digit in the result. 
Result so far: 15763.3703
Subtract 162 from 200 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 11:
54 goes into 380 7 times with a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 15763.37037
The remainder is 2 after subtracting 378 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 12:
If we divide 20 by 54, we get 0 and a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 15763.37037
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 13:
54 goes into 200 3 times with a remainder of 38.
The next digit of our result is 3. 
Result so far: 15763.3703703
If we subtract 162 from 200, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 14:
54 goes into 380 7 times with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 15763.37037037
Deduct 378 from 380 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

After the division, we end up with 15763.37037037 and a remainder of 2e-09.
