We're dividing 45380942 by 993 
Our goal is to divide 45380942 by 993.

Let's proceed to step 1:
The number 993 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our 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 / 993

On to step 2:
45 divided by 993 is 0 with a remainder of 45.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Bring next digit (3) of the dividend behind the 45 and repeat the process: 453 / 993

Advancing to step 3:
When dividing 453 by 993, we get 0 with a remainder of 453.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 453, we get 453.
Bring next digit (8) of the dividend behind the 453 and repeat the process: 4538 / 993

Step 4:
4538 divided by 993 is 4 with a remainder of 566.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 3972 from 4538 and we're left with 566.
Bring next digit (0) of the dividend behind the 566 and repeat the process: 5660 / 993

Going ahead to step 5:
993 goes into 5660 5 times with a remainder of 695.
Record the quotient 5 as the next digit in the result. 
Result so far: 45.0
The remainder is 695 after subtracting 4965 from 5660.
Take the next digit (9) from the dividend and append it to 695, then repeat: 6959 / 993

Step 6:
When dividing 6959 by 993, we get 7 with a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 457.0
Subtracting 6951 from 6959 leaves us with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 993

Moving on to step 7:
The number 993 fits into 84 0 times, leaving a remainder of 84.
Record the quotient 0 as the next digit in the result. 
Result so far: 4570.0
Deduct 0 from 84 and we're left with 84.
Fetch the next digit (2) from the dividend, attach it to 84 and continue: 842 / 993

Moving on to step 8:
When dividing 842 by 993, we get 0 with a remainder of 842.
Record the quotient 0 as the next digit in the result. 
Result so far: 45700.0
The remainder is 842 after subtracting 0 from 842.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8420, and continue the process.

Advancing to step 9:
8420 divided by 993 is 8 with a remainder of 476.
Record the quotient 8 as the next digit in the result. 
Result so far: 45700.8
If we subtract 7944 from 8420, we get 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

On to step 10:
993 can be fit into 4760 4 times, resulting in a remainder of 788.
The number 4 becomes the next digit in our result. 
Result so far: 45700.84
Subtract 3972 from 4760 to get 788.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7880, and continue the process.

Advancing to step 11:
993 goes into 7880 7 times with a remainder of 929.
Use 7 as the next digit of our solution. 
Result so far: 45700.847
Subtract 6951 from 7880 to get 929.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9290, and continue the process.

Moving on to step 12:
993 goes into 9290 9 times with a remainder of 353.
Record the quotient 9 as the next digit in the result. 
Result so far: 45700.8479
If we take 8937 away from 9290, we end up with 353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

Moving on to step 13:
The number 993 fits into 3530 3 times, leaving a remainder of 551.
Put 3 as the next digit of the answer. 
Result so far: 45700.84793
Deduct 2979 from 3530 and we're left with 551.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5510, and continue the process.

Advancing to step 14:
993 goes into 5510 5 times with a remainder of 545.
Put 5 as the next digit of the answer. 
Result so far: 45700.847935
If we take 4965 away from 5510, we end up with 545.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5450, and continue the process.

On to step 15:
When dividing 5450 by 993, we get 5 with a remainder of 485.
Record the quotient 5 as the next digit in the result. 
Result so far: 45700.8479355
If we subtract 4965 from 5450, we get 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

The final result is 45700.8479355 with a remainder of 4.85e-06.
