453643 ÷ 54 
We want to figure out the number of times 453643 can be divided by 54.

Advancing to step 1:
When dividing 4 by 54, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 54

Step 2:
54 goes into 45 0 times with a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Bring next digit (3) of the dividend behind the 45 and repeat the process: 453 / 54

On to step 3:
54 goes into 453 8 times with a remainder of 21.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 432 from 453 and we're left with 21.
Bring next digit (6) of the dividend behind the 21 and repeat the process: 216 / 54

On to step 4:
54 goes into 216 4 times with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 84.0
Deduct 216 from 216 and we're left with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 54

Step 5:
54 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 840.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 54

Moving on to step 6:
When dividing 43 by 54, we get 0 with a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 8400.0
The remainder is 43 after subtracting 0 from 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 7:
54 goes into 430 7 times with a remainder of 52.
Write down 7 as next digit of the result. 
Result so far: 8400.7
Subtracting 378 from 430 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 8:
The number 54 fits into 520 9 times, leaving a remainder of 34.
Put 9 as the next digit of the answer. 
Result so far: 8400.79
If we take 486 away from 520, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 9:
54 can be fit into 340 6 times, resulting in a remainder of 16.
The next digit of our result is 6. 
Result so far: 8400.796
If we subtract 324 from 340, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 10:
If we divide 160 by 54, we get 2 and a remainder of 52.
Use 2 as the next digit of our solution. 
Result so far: 8400.7962
The remainder is 52 after subtracting 108 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 11:
When dividing 520 by 54, we get 9 with a remainder of 34.
Record the quotient 9 as the next digit in the result. 
Result so far: 8400.79629
If we take 486 away from 520, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 12:
When dividing 340 by 54, we get 6 with a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 8400.796296
Subtract 324 from 340 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 13:
54 goes into 160 2 times with a remainder of 52.
Record the quotient 2 as the next digit in the result. 
Result so far: 8400.7962962
If we subtract 108 from 160, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 14:
54 can be fit into 520 9 times, resulting in a remainder of 34.
Record the quotient 9 as the next digit in the result. 
Result so far: 8400.79629629
Subtracting 486 from 520 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Our division results in 8400.79629629 with a remaining 3.4e-08.
