84273980 ÷ 54 
We want to figure out the number of times 84273980 can be divided by 54.

Step 1:
When dividing 8 by 54, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 54

On to step 2:
84 divided by 54 is 1 with a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 54 from 84, we get 30.
Include the next digit (2) from the dividend after 30, then repeat: 302 / 54

Going ahead to step 3:
54 can be fit into 302 5 times, resulting in a remainder of 32.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtracting 270 from 302 leaves us with 32.
Append the next digit (7) from the dividend to 32 and continue with: 327 / 54

Step 4:
The number 54 fits into 327 6 times, leaving a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 156.0
If we subtract 324 from 327, we get 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 54

Let's proceed to step 5:
54 can be fit into 33 0 times, resulting in a remainder of 33.
Record the quotient 0 as the next digit in the result. 
Result so far: 1560.0
Subtract 0 from 33 to get 33.
Bring next digit (9) of the dividend behind the 33 and repeat the process: 339 / 54

Moving on to step 6:
When dividing 339 by 54, we get 6 with a remainder of 15.
The number 6 becomes the next digit in our result. 
Result so far: 15606.0
The remainder is 15 after subtracting 324 from 339.
Include the next digit (8) from the dividend after 15, then repeat: 158 / 54

Advancing to step 7:
If we divide 158 by 54, we get 2 and a remainder of 50.
The next digit of our result is 2. 
Result so far: 156062.0
Deduct 108 from 158 and we're left with 50.
Bring next digit (0) of the dividend behind the 50 and repeat the process: 500 / 54

Going ahead to step 8:
54 can be fit into 500 9 times, resulting in a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 1560629.0
Subtracting 486 from 500 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 9:
If we divide 140 by 54, we get 2 and a remainder of 32.
The next digit of our result is 2. 
Result so far: 1560629.2
Subtract 108 from 140 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 10:
When dividing 320 by 54, we get 5 with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 1560629.25
Deduct 270 from 320 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 11:
If we divide 500 by 54, we get 9 and a remainder of 14.
Put 9 as the next digit of the answer. 
Result so far: 1560629.259
If we subtract 486 from 500, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 12:
140 divided by 54 is 2 with a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 1560629.2592
Subtracting 108 from 140 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 13:
54 can be fit into 320 5 times, resulting in a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 1560629.25925
If we take 270 away from 320, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 14:
54 goes into 500 9 times with a remainder of 14.
The number 9 becomes the next digit in our result. 
Result so far: 1560629.259259
Deduct 486 from 500 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 15:
54 can be fit into 140 2 times, resulting in a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 1560629.2592592
Subtracting 108 from 140 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 16:
If we divide 320 by 54, we get 5 and a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 1560629.25925925
Subtracting 270 from 320 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Our division results in 1560629.25925925 with a remaining 5e-08.
