Let's divide 30011188 by 423
We want to divide 30011188 by 423.

Step 1:
If we divide 3 by 423, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 423

Advancing to step 2:
423 can be fit into 30 0 times, resulting in a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Grab the next digit (0) from the dividend, add it to 30, then carry on: 300 / 423

Advancing to step 3:
300 divided by 423 is 0 with a remainder of 300.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 300 leaves us with 300.
Append the next digit (1) from the dividend to 300 and continue with: 3001 / 423

On to step 4:
423 goes into 3001 7 times with a remainder of 40.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 2961 from 3001 and we're left with 40.
Fetch the next digit (1) from the dividend, attach it to 40 and continue: 401 / 423

Let's proceed to step 5:
When dividing 401 by 423, we get 0 with a remainder of 401.
The number 0 becomes the next digit in our result. 
Result so far: 70.0
Deduct 0 from 401 and we're left with 401.
Include the next digit (1) from the dividend after 401, then repeat: 4011 / 423

Advancing to step 6:
4011 divided by 423 is 9 with a remainder of 204.
Record the quotient 9 as the next digit in the result. 
Result so far: 709.0
The remainder is 204 after subtracting 3807 from 4011.
Take the next digit (8) from the dividend and append it to 204, then repeat: 2048 / 423

Advancing to step 7:
423 goes into 2048 4 times with a remainder of 356.
Record the quotient 4 as the next digit in the result. 
Result so far: 7094.0
The remainder is 356 after subtracting 1692 from 2048.
Grab the next digit (8) from the dividend, add it to 356, then carry on: 3568 / 423

On to step 8:
The number 423 fits into 3568 8 times, leaving a remainder of 184.
Write down 8 as next digit of the result. 
Result so far: 70948.0
If we take 3384 away from 3568, we end up with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Step 9:
When dividing 1840 by 423, we get 4 with a remainder of 148.
The number 4 becomes the next digit in our result. 
Result so far: 70948.4
If we take 1692 away from 1840, we end up with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

On to step 10:
423 can be fit into 1480 3 times, resulting in a remainder of 211.
The next digit of our result is 3. 
Result so far: 70948.43
If we take 1269 away from 1480, we end up 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.

Step 11:
If we divide 2110 by 423, we get 4 and a remainder of 418.
The number 4 becomes the next digit in our result. 
Result so far: 70948.434
Subtracting 1692 from 2110 leaves us with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Step 12:
423 goes into 4180 9 times with a remainder of 373.
Record the quotient 9 as the next digit in the result. 
Result so far: 70948.4349
Subtracting 3807 from 4180 leaves us with 373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

Let's proceed to step 13:
If we divide 3730 by 423, we get 8 and a remainder of 346.
Record the quotient 8 as the next digit in the result. 
Result so far: 70948.43498
If we subtract 3384 from 3730, we get 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Let's proceed to step 14:
The number 423 fits into 3460 8 times, leaving a remainder of 76.
Write down 8 as next digit of the result. 
Result so far: 70948.434988
Subtracting 3384 from 3460 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The quotient of the division is 70948.434988, and the remainder is 7.6e-06.
