We're dividing 21423003 by 347 
Our goal is to divide 21423003 by 347.

Step 1:
If we divide 2 by 347, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 347

Moving on to step 2:
When dividing 21 by 347, we get 0 with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Bring next digit (4) of the dividend behind the 21 and repeat the process: 214 / 347

Going ahead to step 3:
The number 347 fits into 214 0 times, leaving a remainder of 214.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 214, we get 214.
Include the next digit (2) from the dividend after 214, then repeat: 2142 / 347

Going ahead to step 4:
347 goes into 2142 6 times with a remainder of 60.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtracting 2082 from 2142 leaves us with 60.
Append the next digit (3) from the dividend to 60 and continue with: 603 / 347

Step 5:
When dividing 603 by 347, we get 1 with a remainder of 256.
Put 1 as the next digit of the answer. 
Result so far: 61.0
If we take 347 away from 603, we end up with 256.
Bring next digit (0) of the dividend behind the 256 and repeat the process: 2560 / 347

Moving on to step 6:
If we divide 2560 by 347, we get 7 and a remainder of 131.
Write down 7 as next digit of the result. 
Result so far: 617.0
If we take 2429 away from 2560, we end up with 131.
Take the next digit (0) from the dividend and append it to 131, then repeat: 1310 / 347

On to step 7:
The number 347 fits into 1310 3 times, leaving a remainder of 269.
Record the quotient 3 as the next digit in the result. 
Result so far: 6173.0
Subtract 1041 from 1310 to get 269.
Take the next digit (3) from the dividend and append it to 269, then repeat: 2693 / 347

Let's proceed to step 8:
2693 divided by 347 is 7 with a remainder of 264.
Write down 7 as next digit of the result. 
Result so far: 61737.0
Subtract 2429 from 2693 to get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Going ahead to step 9:
347 goes into 2640 7 times with a remainder of 211.
Use 7 as the next digit of our solution. 
Result so far: 61737.7
Deduct 2429 from 2640 and we're left with 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Advancing to step 10:
The number 347 fits into 2110 6 times, leaving a remainder of 28.
Use 6 as the next digit of our solution. 
Result so far: 61737.76
Subtract 2082 from 2110 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 11:
280 divided by 347 is 0 with a remainder of 280.
The next digit of our result is 0. 
Result so far: 61737.76
If we take 0 away from 280, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 12:
347 goes into 2800 8 times with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 61737.7608
The remainder is 24 after subtracting 2776 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 13:
347 can be fit into 240 0 times, resulting in a remainder of 240.
The next digit of our result is 0. 
Result so far: 61737.7608
The remainder is 240 after subtracting 0 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 14:
347 can be fit into 2400 6 times, resulting in a remainder of 318.
Record the quotient 6 as the next digit in the result. 
Result so far: 61737.760806
The remainder is 318 after subtracting 2082 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Let's proceed to step 15:
When dividing 3180 by 347, we get 9 with a remainder of 57.
Use 9 as the next digit of our solution. 
Result so far: 61737.7608069
Subtracting 3123 from 3180 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 16:
347 goes into 570 1 times with a remainder of 223.
Use 1 as the next digit of our solution. 
Result so far: 61737.76080691
Deduct 347 from 570 and we're left with 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

The final result is 61737.76080691 with a remainder of 2.23e-07.
