74513452 divided by 423 
We want to figure out the number of times 74513452 can be divided by 423.

Step 1:
When dividing 7 by 423, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 423

Going ahead to step 2:
The number 423 fits into 74 0 times, leaving a remainder of 74.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 74 to get 74.
Include the next digit (5) from the dividend after 74, then repeat: 745 / 423

Let's proceed to step 3:
423 can be fit into 745 1 times, resulting in a remainder of 322.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 423 from 745 to get 322.
Append the next digit (1) from the dividend to 322 and continue with: 3221 / 423

Advancing to step 4:
423 goes into 3221 7 times with a remainder of 260.
The next digit of our result is 7. 
Result so far: 17.0
If we subtract 2961 from 3221, we get 260.
Append the next digit (3) from the dividend to 260 and continue with: 2603 / 423

On to step 5:
423 can be fit into 2603 6 times, resulting in a remainder of 65.
Use 6 as the next digit of our solution. 
Result so far: 176.0
The remainder is 65 after subtracting 2538 from 2603.
Bring next digit (4) of the dividend behind the 65 and repeat the process: 654 / 423

Step 6:
654 divided by 423 is 1 with a remainder of 231.
Use 1 as the next digit of our solution. 
Result so far: 1761.0
Deduct 423 from 654 and we're left with 231.
Fetch the next digit (5) from the dividend, attach it to 231 and continue: 2315 / 423

Advancing to step 7:
If we divide 2315 by 423, we get 5 and a remainder of 200.
The number 5 becomes the next digit in our result. 
Result so far: 17615.0
Subtracting 2115 from 2315 leaves us with 200.
Fetch the next digit (2) from the dividend, attach it to 200 and continue: 2002 / 423

Step 8:
423 goes into 2002 4 times with a remainder of 310.
Put 4 as the next digit of the answer. 
Result so far: 176154.0
The remainder is 310 after subtracting 1692 from 2002.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Going ahead to step 9:
When dividing 3100 by 423, we get 7 with a remainder of 139.
Write down 7 as next digit of the result. 
Result so far: 176154.7
If we subtract 2961 from 3100, we get 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Step 10:
423 can be fit into 1390 3 times, resulting in a remainder of 121.
The number 3 becomes the next digit in our result. 
Result so far: 176154.73
Subtract 1269 from 1390 to get 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Going ahead to step 11:
1210 divided by 423 is 2 with a remainder of 364.
Use 2 as the next digit of our solution. 
Result so far: 176154.732
Subtracting 846 from 1210 leaves us with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Advancing to step 12:
When dividing 3640 by 423, we get 8 with a remainder of 256.
Write down 8 as next digit of the result. 
Result so far: 176154.7328
Subtract 3384 from 3640 to get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Let's proceed to step 13:
423 can be fit into 2560 6 times, resulting in a remainder of 22.
The next digit of our result is 6. 
Result so far: 176154.73286
Subtract 2538 from 2560 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 14:
If we divide 220 by 423, we get 0 and a remainder of 220.
The next digit of our result is 0. 
Result so far: 176154.73286
Subtracting 0 from 220 leaves us with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Advancing to step 15:
The number 423 fits into 2200 5 times, leaving a remainder of 85.
The next digit of our result is 5. 
Result so far: 176154.7328605
Subtracting 2115 from 2200 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 16:
423 can be fit into 850 2 times, resulting in a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 176154.73286052
If we subtract 846 from 850, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 176154.73286052, with a leftover of 4e-09.
