We're dividing 45753619 by 738 
We want to figure out the number of times 45753619 can be divided by 738.

Step 1:
If we divide 4 by 738, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 738

Step 2:
738 goes into 45 0 times with a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Append the next digit (7) from the dividend to 45 and continue with: 457 / 738

Step 3:
738 goes into 457 0 times with a remainder of 457.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 457 to get 457.
Include the next digit (5) from the dividend after 457, then repeat: 4575 / 738

Advancing to step 4:
When dividing 4575 by 738, we get 6 with a remainder of 147.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Deduct 4428 from 4575 and we're left with 147.
Grab the next digit (3) from the dividend, add it to 147, then carry on: 1473 / 738

Moving on to step 5:
The number 738 fits into 1473 1 times, leaving a remainder of 735.
Put 1 as the next digit of the answer. 
Result so far: 61.0
If we take 738 away from 1473, we end up with 735.
Take the next digit (6) from the dividend and append it to 735, then repeat: 7356 / 738

Advancing to step 6:
If we divide 7356 by 738, we get 9 and a remainder of 714.
Put 9 as the next digit of the answer. 
Result so far: 619.0
Subtract 6642 from 7356 to get 714.
Take the next digit (1) from the dividend and append it to 714, then repeat: 7141 / 738

Advancing to step 7:
738 goes into 7141 9 times with a remainder of 499.
Put 9 as the next digit of the answer. 
Result so far: 6199.0
Subtract 6642 from 7141 to get 499.
Take the next digit (9) from the dividend and append it to 499, then repeat: 4999 / 738

Advancing to step 8:
When dividing 4999 by 738, we get 6 with a remainder of 571.
The number 6 becomes the next digit in our result. 
Result so far: 61996.0
The remainder is 571 after subtracting 4428 from 4999.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5710, and continue the process.

Let's proceed to step 9:
If we divide 5710 by 738, we get 7 and a remainder of 544.
Use 7 as the next digit of our solution. 
Result so far: 61996.7
If we subtract 5166 from 5710, we get 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Moving on to step 10:
738 can be fit into 5440 7 times, resulting in a remainder of 274.
Write down 7 as next digit of the result. 
Result so far: 61996.77
Deduct 5166 from 5440 and we're left with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

After the division, we end up with 61996.77 and a remainder of 0.274.
