53479990 ÷ 814 
Our goal is to divide 53479990 by 814.

Moving on to step 1:
If we divide 5 by 814, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 814

Going ahead to step 2:
The number 814 fits into 53 0 times, leaving a remainder of 53.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 53 and we're left with 53.
Take the next digit (4) from the dividend and append it to 53, then repeat: 534 / 814

Going ahead to step 3:
When dividing 534 by 814, we get 0 with a remainder of 534.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 534, we get 534.
Bring next digit (7) of the dividend behind the 534 and repeat the process: 5347 / 814

On to step 4:
When dividing 5347 by 814, we get 6 with a remainder of 463.
The next digit of our result is 6. 
Result so far: 6.0
If we take 4884 away from 5347, we end up with 463.
Fetch the next digit (9) from the dividend, attach it to 463 and continue: 4639 / 814

Advancing to step 5:
814 goes into 4639 5 times with a remainder of 569.
Put 5 as the next digit of the answer. 
Result so far: 65.0
Subtracting 4070 from 4639 leaves us with 569.
Append the next digit (9) from the dividend to 569 and continue with: 5699 / 814

On to step 6:
814 goes into 5699 7 times with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 657.0
Deduct 5698 from 5699 and we're left with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 814

Step 7:
19 divided by 814 is 0 with a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 6570.0
The remainder is 19 after subtracting 0 from 19.
Take the next digit (0) from the dividend and append it to 19, then repeat: 190 / 814

Step 8:
If we divide 190 by 814, we get 0 and a remainder of 190.
Use 0 as the next digit of our solution. 
Result so far: 65700.0
If we subtract 0 from 190, we get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Advancing to step 9:
814 can be fit into 1900 2 times, resulting in a remainder of 272.
Record the quotient 2 as the next digit in the result. 
Result so far: 65700.2
Deduct 1628 from 1900 and we're left with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Advancing to step 10:
2720 divided by 814 is 3 with a remainder of 278.
Put 3 as the next digit of the answer. 
Result so far: 65700.23
The remainder is 278 after subtracting 2442 from 2720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Step 11:
814 goes into 2780 3 times with a remainder of 338.
The number 3 becomes the next digit in our result. 
Result so far: 65700.233
Deduct 2442 from 2780 and we're left with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Our division results in 65700.233 with a remaining 0.0338.
