We look at the division of 54372999 by 997 
Let's see how many times 997 fits into 54372999.

Moving on to step 1:
997 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 997

On to step 2:
997 goes into 54 0 times with a remainder of 54.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 54 leaves us with 54.
Take the next digit (3) from the dividend and append it to 54, then repeat: 543 / 997

On to step 3:
When dividing 543 by 997, we get 0 with a remainder of 543.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 543 leaves us with 543.
Grab the next digit (7) from the dividend, add it to 543, then carry on: 5437 / 997

Let's proceed to step 4:
5437 divided by 997 is 5 with a remainder of 452.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 4985 from 5437, we get 452.
Bring next digit (2) of the dividend behind the 452 and repeat the process: 4522 / 997

On to step 5:
997 goes into 4522 4 times with a remainder of 534.
The number 4 becomes the next digit in our result. 
Result so far: 54.0
If we subtract 3988 from 4522, we get 534.
Include the next digit (9) from the dividend after 534, then repeat: 5349 / 997

Moving on to step 6:
When dividing 5349 by 997, we get 5 with a remainder of 364.
The number 5 becomes the next digit in our result. 
Result so far: 545.0
If we subtract 4985 from 5349, we get 364.
Take the next digit (9) from the dividend and append it to 364, then repeat: 3649 / 997

Step 7:
If we divide 3649 by 997, we get 3 and a remainder of 658.
Put 3 as the next digit of the answer. 
Result so far: 5453.0
If we take 2991 away from 3649, we end up with 658.
Include the next digit (9) from the dividend after 658, then repeat: 6589 / 997

Moving on to step 8:
The number 997 fits into 6589 6 times, leaving a remainder of 607.
The next digit of our result is 6. 
Result so far: 54536.0
Deduct 5982 from 6589 and we're left with 607.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6070, and continue the process.

Moving on to step 9:
6070 divided by 997 is 6 with a remainder of 88.
Put 6 as the next digit of the answer. 
Result so far: 54536.6
Deduct 5982 from 6070 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 10:
The number 997 fits into 880 0 times, leaving a remainder of 880.
Record the quotient 0 as the next digit in the result. 
Result so far: 54536.6
Subtracting 0 from 880 leaves us with 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8800, and continue the process.

Let's proceed to step 11:
997 can be fit into 8800 8 times, resulting in a remainder of 824.
The next digit of our result is 8. 
Result so far: 54536.608
If we take 7976 away from 8800, we end up 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.

Going ahead to step 12:
When dividing 8240 by 997, we get 8 with a remainder of 264.
Write down 8 as next digit of the result. 
Result so far: 54536.6088
Deduct 7976 from 8240 and we're left with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

The final outcome is 54536.6088, with a leftover of 0.00264.
