We look at the division of 51201222 by 235 
Let's see how many times 235 fits into 51201222.

Going ahead to step 1:
When dividing 5 by 235, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 235

Advancing to step 2:
If we divide 51 by 235, we get 0 and a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Append the next digit (2) from the dividend to 51 and continue with: 512 / 235

Let's proceed to step 3:
235 goes into 512 2 times with a remainder of 42.
The next digit of our result is 2. 
Result so far: 2.0
If we take 470 away from 512, we end up with 42.
Bring next digit (0) of the dividend behind the 42 and repeat the process: 420 / 235

Moving on to step 4:
When dividing 420 by 235, we get 1 with a remainder of 185.
The next digit of our result is 1. 
Result so far: 21.0
Subtracting 235 from 420 leaves us with 185.
Bring next digit (1) of the dividend behind the 185 and repeat the process: 1851 / 235

Step 5:
235 goes into 1851 7 times with a remainder of 206.
Record the quotient 7 as the next digit in the result. 
Result so far: 217.0
Deduct 1645 from 1851 and we're left with 206.
Fetch the next digit (2) from the dividend, attach it to 206 and continue: 2062 / 235

Going ahead to step 6:
235 can be fit into 2062 8 times, resulting in a remainder of 182.
The next digit of our result is 8. 
Result so far: 2178.0
Subtracting 1880 from 2062 leaves us with 182.
Bring next digit (2) of the dividend behind the 182 and repeat the process: 1822 / 235

Going ahead to step 7:
When dividing 1822 by 235, we get 7 with a remainder of 177.
Put 7 as the next digit of the answer. 
Result so far: 21787.0
Subtract 1645 from 1822 to get 177.
Fetch the next digit (2) from the dividend, attach it to 177 and continue: 1772 / 235

Let's proceed to step 8:
235 goes into 1772 7 times with a remainder of 127.
Record the quotient 7 as the next digit in the result. 
Result so far: 217877.0
Subtract 1645 from 1772 to get 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Step 9:
When dividing 1270 by 235, we get 5 with a remainder of 95.
Write down 5 as next digit of the result. 
Result so far: 217877.5
Deduct 1175 from 1270 and we're left with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

On to step 10:
When dividing 950 by 235, we get 4 with a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 217877.54
Subtracting 940 from 950 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.

Step 11:
If we divide 100 by 235, we get 0 and a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 217877.54
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 12:
When dividing 1000 by 235, we get 4 with a remainder of 60.
Put 4 as the next digit of the answer. 
Result so far: 217877.5404
Subtract 940 from 1000 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 13:
235 goes into 600 2 times with a remainder of 130.
Use 2 as the next digit of our solution. 
Result so far: 217877.54042
If we take 470 away from 600, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 14:
1300 divided by 235 is 5 with a remainder of 125.
Use 5 as the next digit of our solution. 
Result so far: 217877.540425
If we subtract 1175 from 1300, we get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Moving on to step 15:
The number 235 fits into 1250 5 times, leaving a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 217877.5404255
Subtracting 1175 from 1250 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

The final result is 217877.5404255 with a remainder of 7.5e-07.
