421276 ÷ 53 
We want to figure out the number of times 421276 can be divided by 53.

Step 1:
If we divide 4 by 53, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 53

Step 2:
53 can be fit into 42 0 times, resulting in a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Bring next digit (1) of the dividend behind the 42 and repeat the process: 421 / 53

Moving on to step 3:
The number 53 fits into 421 7 times, leaving a remainder of 50.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 371 from 421 and we're left with 50.
Bring next digit (2) of the dividend behind the 50 and repeat the process: 502 / 53

Advancing to step 4:
If we divide 502 by 53, we get 9 and a remainder of 25.
Record the quotient 9 as the next digit in the result. 
Result so far: 79.0
The remainder is 25 after subtracting 477 from 502.
Grab the next digit (7) from the dividend, add it to 25, then carry on: 257 / 53

Let's proceed to step 5:
If we divide 257 by 53, we get 4 and a remainder of 45.
Write down 4 as next digit of the result. 
Result so far: 794.0
Deduct 212 from 257 and we're left with 45.
Bring next digit (6) of the dividend behind the 45 and repeat the process: 456 / 53

Step 6:
If we divide 456 by 53, we get 8 and a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 7948.0
Subtracting 424 from 456 leaves us 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.

Going ahead to step 7:
When dividing 320 by 53, we get 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 7948.6
If we subtract 318 from 320, we get 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 8:
53 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 7948.6
If we take 0 away from 20, we end up 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.

Going ahead to step 9:
When dividing 200 by 53, we get 3 with a remainder of 41.
Write down 3 as next digit of the result. 
Result so far: 7948.603
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 10:
53 goes into 410 7 times with a remainder of 39.
Use 7 as the next digit of our solution. 
Result so far: 7948.6037
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.

Let's proceed to step 11:
53 can be fit into 390 7 times, resulting in a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 7948.60377
Deduct 371 from 390 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Our division results in 7948.60377 with a remaining 1.9e-05.
