54435685 ÷ 168 
We want to figure out the number of times 54435685 can be divided by 168.

On to step 1:
5 divided by 168 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 168

Going ahead to step 2:
168 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 (4) from the dividend and append it to 54, then repeat: 544 / 168

Advancing to step 3:
The number 168 fits into 544 3 times, leaving a remainder of 40.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 40 after subtracting 504 from 544.
Fetch the next digit (3) from the dividend, attach it to 40 and continue: 403 / 168

Advancing to step 4:
403 divided by 168 is 2 with a remainder of 67.
Write down 2 as next digit of the result. 
Result so far: 32.0
Deduct 336 from 403 and we're left with 67.
Bring next digit (5) of the dividend behind the 67 and repeat the process: 675 / 168

Step 5:
675 divided by 168 is 4 with a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 324.0
The remainder is 3 after subtracting 672 from 675.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 168

Moving on to step 6:
168 can be fit into 36 0 times, resulting in a remainder of 36.
Use 0 as the next digit of our solution. 
Result so far: 3240.0
If we subtract 0 from 36, we get 36.
Append the next digit (8) from the dividend to 36 and continue with: 368 / 168

Moving on to step 7:
If we divide 368 by 168, we get 2 and a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 32402.0
If we take 336 away from 368, we end up with 32.
Append the next digit (5) from the dividend to 32 and continue with: 325 / 168

Step 8:
168 goes into 325 1 times with a remainder of 157.
Write down 1 as next digit of the result. 
Result so far: 324021.0
Subtract 168 from 325 to get 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Moving on to step 9:
When dividing 1570 by 168, we get 9 with a remainder of 58.
Record the quotient 9 as the next digit in the result. 
Result so far: 324021.9
If we take 1512 away from 1570, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 10:
580 divided by 168 is 3 with a remainder of 76.
The next digit of our result is 3. 
Result so far: 324021.93
Subtract 504 from 580 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 11:
168 goes into 760 4 times with a remainder of 88.
Use 4 as the next digit of our solution. 
Result so far: 324021.934
If we subtract 672 from 760, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 12:
168 can be fit into 880 5 times, resulting in a remainder of 40.
The next digit of our result is 5. 
Result so far: 324021.9345
The remainder is 40 after subtracting 840 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 13:
168 can be fit into 400 2 times, resulting in a remainder of 64.
Record the quotient 2 as the next digit in the result. 
Result so far: 324021.93452
Subtract 336 from 400 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 14:
If we divide 640 by 168, we get 3 and a remainder of 136.
Record the quotient 3 as the next digit in the result. 
Result so far: 324021.934523
If we take 504 away from 640, we end up with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Step 15:
If we divide 1360 by 168, we get 8 and a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 324021.9345238
If we take 1344 away from 1360, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 16:
168 can be fit into 160 0 times, resulting in a remainder of 160.
Use 0 as the next digit of our solution. 
Result so far: 324021.9345238
The remainder is 160 after subtracting 0 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

The final result is 324021.9345238 with a remainder of 1.6e-07.
