4520138 ÷ 912 
We're looking to find how many times 912 goes into 4520138.

Let's proceed to step 1:
If we divide 4 by 912, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 912

On to step 2:
912 goes into 45 0 times with a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 45 leaves us with 45.
Bring next digit (2) of the dividend behind the 45 and repeat the process: 452 / 912

Step 3:
The number 912 fits into 452 0 times, leaving a remainder of 452.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 452 leaves us with 452.
Append the next digit (0) from the dividend to 452 and continue with: 4520 / 912

Let's proceed to step 4:
If we divide 4520 by 912, we get 4 and a remainder of 872.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 3648 from 4520 leaves us with 872.
Take the next digit (1) from the dividend and append it to 872, then repeat: 8721 / 912

Step 5:
When dividing 8721 by 912, we get 9 with a remainder of 513.
The number 9 becomes the next digit in our result. 
Result so far: 49.0
Subtracting 8208 from 8721 leaves us with 513.
Take the next digit (3) from the dividend and append it to 513, then repeat: 5133 / 912

Step 6:
5133 divided by 912 is 5 with a remainder of 573.
Use 5 as the next digit of our solution. 
Result so far: 495.0
Deduct 4560 from 5133 and we're left with 573.
Take the next digit (8) from the dividend and append it to 573, then repeat: 5738 / 912

Going ahead to step 7:
5738 divided by 912 is 6 with a remainder of 266.
Write down 6 as next digit of the result. 
Result so far: 4956.0
Subtract 5472 from 5738 to get 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Step 8:
The number 912 fits into 2660 2 times, leaving a remainder of 836.
The number 2 becomes the next digit in our result. 
Result so far: 4956.2
Subtract 1824 from 2660 to get 836.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8360, and continue the process.

On to step 9:
912 goes into 8360 9 times with a remainder of 152.
Put 9 as the next digit of the answer. 
Result so far: 4956.29
Deduct 8208 from 8360 and we're left with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Going ahead to step 10:
912 can be fit into 1520 1 times, resulting in a remainder of 608.
Record the quotient 1 as the next digit in the result. 
Result so far: 4956.291
Deduct 912 from 1520 and we're left with 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Let's proceed to step 11:
If we divide 6080 by 912, we get 6 and a remainder of 608.
Put 6 as the next digit of the answer. 
Result so far: 4956.2916
Deduct 5472 from 6080 and we're left with 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Step 12:
6080 divided by 912 is 6 with a remainder of 608.
Put 6 as the next digit of the answer. 
Result so far: 4956.29166
Deduct 5472 from 6080 and we're left with 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

After the division, we end up with 4956.29166 and a remainder of 0.000608.
