81454080 ÷ 164 
We want to figure out the number of times 81454080 can be divided by 164.

Moving on to step 1:
The number 164 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 164

Going ahead to step 2:
81 divided by 164 is 0 with a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Fetch the next digit (4) from the dividend, attach it to 81 and continue: 814 / 164

On to step 3:
164 goes into 814 4 times with a remainder of 158.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 656 from 814 to get 158.
Bring next digit (5) of the dividend behind the 158 and repeat the process: 1585 / 164

Advancing to step 4:
1585 divided by 164 is 9 with a remainder of 109.
The next digit of our result is 9. 
Result so far: 49.0
If we take 1476 away from 1585, we end up with 109.
Bring next digit (4) of the dividend behind the 109 and repeat the process: 1094 / 164

On to step 5:
1094 divided by 164 is 6 with a remainder of 110.
The number 6 becomes the next digit in our result. 
Result so far: 496.0
Deduct 984 from 1094 and we're left with 110.
Fetch the next digit (0) from the dividend, attach it to 110 and continue: 1100 / 164

Step 6:
1100 divided by 164 is 6 with a remainder of 116.
The next digit of our result is 6. 
Result so far: 4966.0
Deduct 984 from 1100 and we're left with 116.
Append the next digit (8) from the dividend to 116 and continue with: 1168 / 164

Step 7:
When dividing 1168 by 164, we get 7 with a remainder of 20.
Record the quotient 7 as the next digit in the result. 
Result so far: 49667.0
Deduct 1148 from 1168 and we're left with 20.
Grab the next digit (0) from the dividend, add it to 20, then carry on: 200 / 164

On to step 8:
164 goes into 200 1 times with a remainder of 36.
Use 1 as the next digit of our solution. 
Result so far: 496671.0
If we subtract 164 from 200, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 9:
When dividing 360 by 164, we get 2 with a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 496671.2
Deduct 328 from 360 and we're left 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.

Moving on to step 10:
The number 164 fits into 320 1 times, leaving a remainder of 156.
The next digit of our result is 1. 
Result so far: 496671.21
Subtract 164 from 320 to get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Going ahead to step 11:
164 can be fit into 1560 9 times, resulting in a remainder of 84.
Put 9 as the next digit of the answer. 
Result so far: 496671.219
The remainder is 84 after subtracting 1476 from 1560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 12:
164 goes into 840 5 times with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 496671.2195
If we take 820 away from 840, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 13:
164 goes into 200 1 times with a remainder of 36.
Record the quotient 1 as the next digit in the result. 
Result so far: 496671.21951
Subtract 164 from 200 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 14:
164 goes into 360 2 times with a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 496671.219512
Deduct 328 from 360 and we're left 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 15:
164 can be fit into 320 1 times, resulting in a remainder of 156.
Write down 1 as next digit of the result. 
Result so far: 496671.2195121
The remainder is 156 after subtracting 164 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Let's proceed to step 16:
If we divide 1560 by 164, we get 9 and a remainder of 84.
The number 9 becomes the next digit in our result. 
Result so far: 496671.21951219
If we subtract 1476 from 1560, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

The final outcome is 496671.21951219, with a leftover of 8.4e-08.
