61421 ÷ 53 
We want to figure out the number of times 61421 can be divided by 53.

Let's proceed to step 1:
53 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 53

Step 2:
53 can be fit into 61 1 times, resulting in a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 8 after subtracting 53 from 61.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 53

Let's proceed to step 3:
53 can be fit into 84 1 times, resulting in a remainder of 31.
The next digit of our result is 1. 
Result so far: 11.0
If we take 53 away from 84, we end up with 31.
Append the next digit (2) from the dividend to 31 and continue with: 312 / 53

Let's proceed to step 4:
53 goes into 312 5 times with a remainder of 47.
Use 5 as the next digit of our solution. 
Result so far: 115.0
If we take 265 away from 312, we end up with 47.
Bring next digit (1) of the dividend behind the 47 and repeat the process: 471 / 53

Going ahead to step 5:
471 divided by 53 is 8 with a remainder of 47.
Record the quotient 8 as the next digit in the result. 
Result so far: 1158.0
Subtracting 424 from 471 leaves us 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.

Going ahead to step 6:
53 can be fit into 470 8 times, resulting in a remainder of 46.
Put 8 as the next digit of the answer. 
Result so far: 1158.8
If we take 424 away from 470, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 7:
The number 53 fits into 460 8 times, leaving a remainder of 36.
The next digit of our result is 8. 
Result so far: 1158.88
Deduct 424 from 460 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final outcome is 1158.88, with a leftover of 0.036.
