We look at the division of 75388130 by 423 
We want to figure out the number of times 75388130 can be divided by 423.

Let's proceed to 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
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 423

Let's proceed to step 2:
75 divided by 423 is 0 with a remainder of 75.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 75 leaves us with 75.
Bring next digit (3) of the dividend behind the 75 and repeat the process: 753 / 423

Moving on to step 3:
423 can be fit into 753 1 times, resulting in a remainder of 330.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 423 from 753, we get 330.
Include the next digit (8) from the dividend after 330, then repeat: 3308 / 423

Step 4:
The number 423 fits into 3308 7 times, leaving a remainder of 347.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Subtract 2961 from 3308 to get 347.
Take the next digit (8) from the dividend and append it to 347, then repeat: 3478 / 423

Going ahead to step 5:
When dividing 3478 by 423, we get 8 with a remainder of 94.
Write down 8 as next digit of the result. 
Result so far: 178.0
Subtracting 3384 from 3478 leaves us with 94.
Bring next digit (1) of the dividend behind the 94 and repeat the process: 941 / 423

Moving on to step 6:
The number 423 fits into 941 2 times, leaving a remainder of 95.
The number 2 becomes the next digit in our result. 
Result so far: 1782.0
If we take 846 away from 941, we end up with 95.
Take the next digit (3) from the dividend and append it to 95, then repeat: 953 / 423

On to step 7:
953 divided by 423 is 2 with a remainder of 107.
Put 2 as the next digit of the answer. 
Result so far: 17822.0
Deduct 846 from 953 and we're left with 107.
Fetch the next digit (0) from the dividend, attach it to 107 and continue: 1070 / 423

Going ahead to step 8:
When dividing 1070 by 423, we get 2 with a remainder of 224.
Write down 2 as next digit of the result. 
Result so far: 178222.0
Subtracting 846 from 1070 leaves us with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Going ahead to step 9:
423 can be fit into 2240 5 times, resulting in a remainder of 125.
Put 5 as the next digit of the answer. 
Result so far: 178222.5
Deduct 2115 from 2240 and we're left with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Moving on to step 10:
If we divide 1250 by 423, we get 2 and a remainder of 404.
Write down 2 as next digit of the result. 
Result so far: 178222.52
Subtracting 846 from 1250 leaves us with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Let's proceed to step 11:
When dividing 4040 by 423, we get 9 with a remainder of 233.
The number 9 becomes the next digit in our result. 
Result so far: 178222.529
If we subtract 3807 from 4040, we get 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Step 12:
423 goes into 2330 5 times with a remainder of 215.
Write down 5 as next digit of the result. 
Result so far: 178222.5295
Subtracting 2115 from 2330 leaves us with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Moving on to step 13:
If we divide 2150 by 423, we get 5 and a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 178222.52955
Subtract 2115 from 2150 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

After the division, we end up with 178222.52955 and a remainder of 3.5e-05.
