11851 ÷ 53 
We want to figure out the number of times 11851 can be divided by 53.

On to step 1:
1 divided by 53 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 53

Moving on to step 2:
53 goes into 11 0 times with a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 11 after subtracting 0 from 11.
Append the next digit (8) from the dividend to 11 and continue with: 118 / 53

On to step 3:
53 can be fit into 118 2 times, resulting in a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 12 after subtracting 106 from 118.
Grab the next digit (5) from the dividend, add it to 12, then carry on: 125 / 53

Moving on to step 4:
If we divide 125 by 53, we get 2 and a remainder of 19.
The next digit of our result is 2. 
Result so far: 22.0
Deduct 106 from 125 and we're left with 19.
Fetch the next digit (1) from the dividend, attach it to 19 and continue: 191 / 53

Going ahead to step 5:
When dividing 191 by 53, we get 3 with a remainder of 32.
Use 3 as the next digit of our solution. 
Result so far: 223.0
Deduct 159 from 191 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 6:
The number 53 fits into 320 6 times, leaving a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 223.6
Deduct 318 from 320 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.

Going ahead to step 7:
53 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 223.6
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.

Let's proceed to step 8:
If we divide 200 by 53, we get 3 and a remainder of 41.
The next digit of our result is 3. 
Result so far: 223.603
If we subtract 159 from 200, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 9:
53 goes into 410 7 times with a remainder of 39.
Put 7 as the next digit of the answer. 
Result so far: 223.6037
If we take 371 away from 410, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 10:
390 divided by 53 is 7 with a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 223.60377
Subtract 371 from 390 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

After the division, we end up with 223.60377 and a remainder of 1.9e-05.
