430451 ÷ 53 
Let's see how many times 53 fits into 430451.

Moving on to step 1:
4 divided by 53 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 53

Let's proceed to step 2:
43 divided by 53 is 0 with a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 43, we get 43.
Grab the next digit (0) from the dividend, add it to 43, then carry on: 430 / 53

Advancing to step 3:
The number 53 fits into 430 8 times, leaving a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtracting 424 from 430 leaves us with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 53

Advancing to step 4:
53 goes into 64 1 times with a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 81.0
The remainder is 11 after subtracting 53 from 64.
Append the next digit (5) from the dividend to 11 and continue with: 115 / 53

On to step 5:
53 goes into 115 2 times with a remainder of 9.
Write down 2 as next digit of the result. 
Result so far: 812.0
Subtracting 106 from 115 leaves us with 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 53

Moving on to step 6:
91 divided by 53 is 1 with a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 8121.0
The remainder is 38 after subtracting 53 from 91.
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 7:
The number 53 fits into 380 7 times, leaving a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 8121.7
Deduct 371 from 380 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 8:
The number 53 fits into 90 1 times, leaving a remainder of 37.
The next digit of our result is 1. 
Result so far: 8121.71
Subtracting 53 from 90 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 9:
53 can be fit into 370 6 times, resulting in a remainder of 52.
Write down 6 as next digit of the result. 
Result so far: 8121.716
If we subtract 318 from 370, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 10:
520 divided by 53 is 9 with a remainder of 43.
Use 9 as the next digit of our solution. 
Result so far: 8121.7169
The remainder is 43 after subtracting 477 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 11:
If we divide 430 by 53, we get 8 and a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 8121.71698
Subtracting 424 from 430 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 12:
53 goes into 60 1 times with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 8121.716981
Deduct 53 from 60 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 13:
53 can be fit into 70 1 times, resulting in a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 8121.7169811
Deduct 53 from 70 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The final result is 8121.7169811 with a remainder of 1.7e-07.
