Let's divide 54189830 by 993
We're looking to find how many times 993 goes into 54189830.

Step 1:
If we divide 5 by 993, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 993

Let's proceed to step 2:
54 divided by 993 is 0 with a remainder of 54.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 54 to get 54.
Append the next digit (1) from the dividend to 54 and continue with: 541 / 993

Step 3:
If we divide 541 by 993, we get 0 and a remainder of 541.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 541 and we're left with 541.
Fetch the next digit (8) from the dividend, attach it to 541 and continue: 5418 / 993

On to step 4:
If we divide 5418 by 993, we get 5 and a remainder of 453.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 453 after subtracting 4965 from 5418.
Fetch the next digit (9) from the dividend, attach it to 453 and continue: 4539 / 993

Moving on to step 5:
4539 divided by 993 is 4 with a remainder of 567.
The next digit of our result is 4. 
Result so far: 54.0
Deduct 3972 from 4539 and we're left with 567.
Include the next digit (8) from the dividend after 567, then repeat: 5678 / 993

Let's proceed to step 6:
The number 993 fits into 5678 5 times, leaving a remainder of 713.
Record the quotient 5 as the next digit in the result. 
Result so far: 545.0
Deduct 4965 from 5678 and we're left with 713.
Append the next digit (3) from the dividend to 713 and continue with: 7133 / 993

Step 7:
993 can be fit into 7133 7 times, resulting in a remainder of 182.
Record the quotient 7 as the next digit in the result. 
Result so far: 5457.0
Deduct 6951 from 7133 and we're left with 182.
Take the next digit (0) from the dividend and append it to 182, then repeat: 1820 / 993

Advancing to step 8:
1820 divided by 993 is 1 with a remainder of 827.
Use 1 as the next digit of our solution. 
Result so far: 54571.0
Subtracting 993 from 1820 leaves us with 827.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8270, and continue the process.

Advancing to step 9:
8270 divided by 993 is 8 with a remainder of 326.
Record the quotient 8 as the next digit in the result. 
Result so far: 54571.8
Subtracting 7944 from 8270 leaves us with 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

On to step 10:
993 can be fit into 3260 3 times, resulting in a remainder of 281.
The number 3 becomes the next digit in our result. 
Result so far: 54571.83
Deduct 2979 from 3260 and we're left with 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

Advancing to step 11:
The number 993 fits into 2810 2 times, leaving a remainder of 824.
Write down 2 as next digit of the result. 
Result so far: 54571.832
Subtracting 1986 from 2810 leaves us with 824.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8240, and continue the process.

Step 12:
8240 divided by 993 is 8 with a remainder of 296.
The next digit of our result is 8. 
Result so far: 54571.8328
If we subtract 7944 from 8240, we get 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Advancing to step 13:
993 can be fit into 2960 2 times, resulting in a remainder of 974.
Put 2 as the next digit of the answer. 
Result so far: 54571.83282
If we take 1986 away from 2960, we end up with 974.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9740, and continue the process.

Advancing to step 14:
The number 993 fits into 9740 9 times, leaving a remainder of 803.
The next digit of our result is 9. 
Result so far: 54571.832829
If we subtract 8937 from 9740, we get 803.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8030, and continue the process.

Let's proceed to step 15:
When dividing 8030 by 993, we get 8 with a remainder of 86.
The next digit of our result is 8. 
Result so far: 54571.8328298
The remainder is 86 after subtracting 7944 from 8030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Going ahead to step 16:
The number 993 fits into 860 0 times, leaving a remainder of 860.
The next digit of our result is 0. 
Result so far: 54571.8328298
If we subtract 0 from 860, we get 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8600, and continue the process.

The final outcome is 54571.8328298, with a leftover of 8.6e-07.
