We look at the division of 45790321 by 973 
We want to figure out the number of times 45790321 can be divided by 973.

On to step 1:
973 goes into 4 0 times with 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.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 973

On to step 2:
If we divide 45 by 973, we get 0 and a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Fetch the next digit (7) from the dividend, attach it to 45 and continue: 457 / 973

Advancing to step 3:
When dividing 457 by 973, we get 0 with a remainder of 457.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 457, we get 457.
Bring next digit (9) of the dividend behind the 457 and repeat the process: 4579 / 973

Moving on to step 4:
973 goes into 4579 4 times with a remainder of 687.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 3892 from 4579, we get 687.
Fetch the next digit (0) from the dividend, attach it to 687 and continue: 6870 / 973

On to step 5:
When dividing 6870 by 973, we get 7 with a remainder of 59.
The number 7 becomes the next digit in our result. 
Result so far: 47.0
If we subtract 6811 from 6870, we get 59.
Bring next digit (3) of the dividend behind the 59 and repeat the process: 593 / 973

Going ahead to step 6:
973 goes into 593 0 times with a remainder of 593.
Record the quotient 0 as the next digit in the result. 
Result so far: 470.0
The remainder is 593 after subtracting 0 from 593.
Fetch the next digit (2) from the dividend, attach it to 593 and continue: 5932 / 973

Moving on to step 7:
973 can be fit into 5932 6 times, resulting in a remainder of 94.
Use 6 as the next digit of our solution. 
Result so far: 4706.0
Subtract 5838 from 5932 to get 94.
Append the next digit (1) from the dividend to 94 and continue with: 941 / 973

On to step 8:
973 goes into 941 0 times with a remainder of 941.
Use 0 as the next digit of our solution. 
Result so far: 47060.0
If we subtract 0 from 941, we get 941.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9410, and continue the process.

Going ahead to step 9:
If we divide 9410 by 973, we get 9 and a remainder of 653.
The number 9 becomes the next digit in our result. 
Result so far: 47060.9
Subtracting 8757 from 9410 leaves us with 653.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6530, and continue the process.

Step 10:
973 can be fit into 6530 6 times, resulting in a remainder of 692.
Put 6 as the next digit of the answer. 
Result so far: 47060.96
If we subtract 5838 from 6530, we get 692.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6920, and continue the process.

Advancing to step 11:
6920 divided by 973 is 7 with a remainder of 109.
Use 7 as the next digit of our solution. 
Result so far: 47060.967
Subtract 6811 from 6920 to get 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Moving on to step 12:
When dividing 1090 by 973, we get 1 with a remainder of 117.
Record the quotient 1 as the next digit in the result. 
Result so far: 47060.9671
Subtract 973 from 1090 to get 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Moving on to step 13:
973 can be fit into 1170 1 times, resulting in a remainder of 197.
The next digit of our result is 1. 
Result so far: 47060.96711
If we take 973 away from 1170, we end up with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

The final result is 47060.96711 with a remainder of 0.000197.
