We look at the division of 67487436 by 423 
Let's see how many times 423 fits into 67487436.

Step 1:
423 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 423

On to step 2:
When dividing 67 by 423, we get 0 with a remainder of 67.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 67 to get 67.
Append the next digit (4) from the dividend to 67 and continue with: 674 / 423

Advancing to step 3:
423 goes into 674 1 times with a remainder of 251.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 423 from 674, we get 251.
Include the next digit (8) from the dividend after 251, then repeat: 2518 / 423

Going ahead to step 4:
If we divide 2518 by 423, we get 5 and a remainder of 403.
Put 5 as the next digit of the answer. 
Result so far: 15.0
The remainder is 403 after subtracting 2115 from 2518.
Fetch the next digit (7) from the dividend, attach it to 403 and continue: 4037 / 423

Moving on to step 5:
423 can be fit into 4037 9 times, resulting in a remainder of 230.
Put 9 as the next digit of the answer. 
Result so far: 159.0
Subtracting 3807 from 4037 leaves us with 230.
Append the next digit (4) from the dividend to 230 and continue with: 2304 / 423

Advancing to step 6:
The number 423 fits into 2304 5 times, leaving a remainder of 189.
Record the quotient 5 as the next digit in the result. 
Result so far: 1595.0
The remainder is 189 after subtracting 2115 from 2304.
Bring next digit (3) of the dividend behind the 189 and repeat the process: 1893 / 423

Let's proceed to step 7:
1893 divided by 423 is 4 with a remainder of 201.
The next digit of our result is 4. 
Result so far: 15954.0
Subtract 1692 from 1893 to get 201.
Fetch the next digit (6) from the dividend, attach it to 201 and continue: 2016 / 423

Advancing to step 8:
2016 divided by 423 is 4 with a remainder of 324.
Write down 4 as next digit of the result. 
Result so far: 159544.0
The remainder is 324 after subtracting 1692 from 2016.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Advancing to step 9:
When dividing 3240 by 423, we get 7 with a remainder of 279.
Put 7 as the next digit of the answer. 
Result so far: 159544.7
If we take 2961 away from 3240, we end up with 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

On to step 10:
If we divide 2790 by 423, we get 6 and a remainder of 252.
The next digit of our result is 6. 
Result so far: 159544.76
Subtract 2538 from 2790 to get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Step 11:
423 can be fit into 2520 5 times, resulting in a remainder of 405.
Record the quotient 5 as the next digit in the result. 
Result so far: 159544.765
Deduct 2115 from 2520 and we're left with 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

On to step 12:
If we divide 4050 by 423, we get 9 and a remainder of 243.
The next digit of our result is 9. 
Result so far: 159544.7659
Subtract 3807 from 4050 to get 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

On to step 13:
423 can be fit into 2430 5 times, resulting in a remainder of 315.
Use 5 as the next digit of our solution. 
Result so far: 159544.76595
If we subtract 2115 from 2430, we get 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Going ahead to step 14:
423 goes into 3150 7 times with a remainder of 189.
Write down 7 as next digit of the result. 
Result so far: 159544.765957
Subtracting 2961 from 3150 leaves us with 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

On to step 15:
423 can be fit into 1890 4 times, resulting in a remainder of 198.
The number 4 becomes the next digit in our result. 
Result so far: 159544.7659574
The remainder is 198 after subtracting 1692 from 1890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

On to step 16:
423 can be fit into 1980 4 times, resulting in a remainder of 288.
Put 4 as the next digit of the answer. 
Result so far: 159544.76595744
Subtracting 1692 from 1980 leaves us with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

The final outcome is 159544.76595744, with a leftover of 2.88e-07.
