We look at the division of 45378380 by 73 
Our goal is to divide 45378380 by 73.

Let's proceed to step 1:
4 divided by 73 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 73

On to step 2:
The number 73 fits into 45 0 times, leaving 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.
Fetch the next digit (3) from the dividend, attach it to 45 and continue: 453 / 73

On to step 3:
If we divide 453 by 73, we get 6 and a remainder of 15.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 15 after subtracting 438 from 453.
Bring next digit (7) of the dividend behind the 15 and repeat the process: 157 / 73

Advancing to step 4:
73 can be fit into 157 2 times, resulting in a remainder of 11.
Put 2 as the next digit of the answer. 
Result so far: 62.0
If we subtract 146 from 157, we get 11.
Grab the next digit (8) from the dividend, add it to 11, then carry on: 118 / 73

Going ahead to step 5:
The number 73 fits into 118 1 times, leaving a remainder of 45.
Use 1 as the next digit of our solution. 
Result so far: 621.0
The remainder is 45 after subtracting 73 from 118.
Fetch the next digit (3) from the dividend, attach it to 45 and continue: 453 / 73

Going ahead to step 6:
73 goes into 453 6 times with a remainder of 15.
Use 6 as the next digit of our solution. 
Result so far: 6216.0
Subtract 438 from 453 to get 15.
Include the next digit (8) from the dividend after 15, then repeat: 158 / 73

Going ahead to step 7:
73 can be fit into 158 2 times, resulting in a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 62162.0
Subtract 146 from 158 to get 12.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 73

Let's proceed to step 8:
73 can be fit into 120 1 times, resulting in a remainder of 47.
The number 1 becomes the next digit in our result. 
Result so far: 621621.0
If we subtract 73 from 120, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 9:
If we divide 470 by 73, we get 6 and a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 621621.6
Subtracting 438 from 470 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 10:
When dividing 320 by 73, we get 4 with a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 621621.64
Subtracting 292 from 320 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 11:
When dividing 280 by 73, we get 3 with a remainder of 61.
Write down 3 as next digit of the result. 
Result so far: 621621.643
If we take 219 away from 280, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 12:
73 can be fit into 610 8 times, resulting in a remainder of 26.
Record the quotient 8 as the next digit in the result. 
Result so far: 621621.6438
Deduct 584 from 610 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 13:
If we divide 260 by 73, we get 3 and a remainder of 41.
Use 3 as the next digit of our solution. 
Result so far: 621621.64383
Deduct 219 from 260 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 14:
410 divided by 73 is 5 with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 621621.643835
The remainder is 45 after subtracting 365 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 15:
73 goes into 450 6 times with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 621621.6438356
Subtract 438 from 450 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 16:
73 goes into 120 1 times with a remainder of 47.
Write down 1 as next digit of the result. 
Result so far: 621621.64383561
Subtracting 73 from 120 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

The quotient of the division is 621621.64383561, and the remainder is 4.7e-08.
