We divide 53320213 by 431
Our goal is to divide 53320213 by 431.

Going ahead to step 1:
431 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 431

Going ahead to step 2:
If we divide 53 by 431, we get 0 and a remainder of 53.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Append the next digit (3) from the dividend to 53 and continue with: 533 / 431

Moving on to step 3:
431 can be fit into 533 1 times, resulting in a remainder of 102.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 431 away from 533, we end up with 102.
Grab the next digit (2) from the dividend, add it to 102, then carry on: 1022 / 431

Moving on to step 4:
If we divide 1022 by 431, we get 2 and a remainder of 160.
The next digit of our result is 2. 
Result so far: 12.0
If we take 862 away from 1022, we end up with 160.
Include the next digit (0) from the dividend after 160, then repeat: 1600 / 431

Moving on to step 5:
The number 431 fits into 1600 3 times, leaving a remainder of 307.
Record the quotient 3 as the next digit in the result. 
Result so far: 123.0
If we take 1293 away from 1600, we end up with 307.
Grab the next digit (2) from the dividend, add it to 307, then carry on: 3072 / 431

Step 6:
3072 divided by 431 is 7 with a remainder of 55.
Use 7 as the next digit of our solution. 
Result so far: 1237.0
If we subtract 3017 from 3072, we get 55.
Grab the next digit (1) from the dividend, add it to 55, then carry on: 551 / 431

Advancing to step 7:
551 divided by 431 is 1 with a remainder of 120.
The number 1 becomes the next digit in our result. 
Result so far: 12371.0
Deduct 431 from 551 and we're left with 120.
Fetch the next digit (3) from the dividend, attach it to 120 and continue: 1203 / 431

Let's proceed to step 8:
1203 divided by 431 is 2 with a remainder of 341.
Use 2 as the next digit of our solution. 
Result so far: 123712.0
If we subtract 862 from 1203, we get 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Advancing to step 9:
3410 divided by 431 is 7 with a remainder of 393.
Record the quotient 7 as the next digit in the result. 
Result so far: 123712.7
Subtract 3017 from 3410 to get 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

Step 10:
431 goes into 3930 9 times with a remainder of 51.
Use 9 as the next digit of our solution. 
Result so far: 123712.79
If we subtract 3879 from 3930, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 11:
The number 431 fits into 510 1 times, leaving a remainder of 79.
Put 1 as the next digit of the answer. 
Result so far: 123712.791
Deduct 431 from 510 and we're left with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

On to step 12:
If we divide 790 by 431, we get 1 and a remainder of 359.
Record the quotient 1 as the next digit in the result. 
Result so far: 123712.7911
Subtracting 431 from 790 leaves us with 359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

After the division, we end up with 123712.7911 and a remainder of 0.00359.
