81950135 ÷ 548 
We want to figure out the number of times 81950135 can be divided by 548.

Moving on to step 1:
8 divided by 548 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 548

On to step 2:
When dividing 81 by 548, we get 0 with a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Take the next digit (9) from the dividend and append it to 81, then repeat: 819 / 548

Going ahead to step 3:
819 divided by 548 is 1 with a remainder of 271.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 271 after subtracting 548 from 819.
Grab the next digit (5) from the dividend, add it to 271, then carry on: 2715 / 548

On to step 4:
When dividing 2715 by 548, we get 4 with a remainder of 523.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we take 2192 away from 2715, we end up with 523.
Append the next digit (0) from the dividend to 523 and continue with: 5230 / 548

Going ahead to step 5:
548 goes into 5230 9 times with a remainder of 298.
Use 9 as the next digit of our solution. 
Result so far: 149.0
Deduct 4932 from 5230 and we're left with 298.
Bring next digit (1) of the dividend behind the 298 and repeat the process: 2981 / 548

Step 6:
2981 divided by 548 is 5 with a remainder of 241.
The number 5 becomes the next digit in our result. 
Result so far: 1495.0
Deduct 2740 from 2981 and we're left with 241.
Grab the next digit (3) from the dividend, add it to 241, then carry on: 2413 / 548

Moving on to step 7:
The number 548 fits into 2413 4 times, leaving a remainder of 221.
Use 4 as the next digit of our solution. 
Result so far: 14954.0
If we take 2192 away from 2413, we end up with 221.
Grab the next digit (5) from the dividend, add it to 221, then carry on: 2215 / 548

On to step 8:
548 goes into 2215 4 times with a remainder of 23.
The next digit of our result is 4. 
Result so far: 149544.0
Subtract 2192 from 2215 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 9:
If we divide 230 by 548, we get 0 and a remainder of 230.
The next digit of our result is 0. 
Result so far: 149544.0
Subtracting 0 from 230 leaves us with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Let's proceed to step 10:
If we divide 2300 by 548, we get 4 and a remainder of 108.
The number 4 becomes the next digit in our result. 
Result so far: 149544.04
Subtracting 2192 from 2300 leaves us with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Advancing to step 11:
548 can be fit into 1080 1 times, resulting in a remainder of 532.
Write down 1 as next digit of the result. 
Result so far: 149544.041
The remainder is 532 after subtracting 548 from 1080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Let's proceed to step 12:
When dividing 5320 by 548, we get 9 with a remainder of 388.
Use 9 as the next digit of our solution. 
Result so far: 149544.0419
Subtract 4932 from 5320 to get 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

On to step 13:
548 goes into 3880 7 times with a remainder of 44.
The next digit of our result is 7. 
Result so far: 149544.04197
The remainder is 44 after subtracting 3836 from 3880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 14:
The number 548 fits into 440 0 times, leaving a remainder of 440.
Put 0 as the next digit of the answer. 
Result so far: 149544.04197
Subtract 0 from 440 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Step 15:
548 goes into 4400 8 times with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 149544.0419708
Subtract 4384 from 4400 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 16:
The number 548 fits into 160 0 times, leaving a remainder of 160.
Record the quotient 0 as the next digit in the result. 
Result so far: 149544.0419708
Subtract 0 from 160 to get 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 quotient of the division is 149544.0419708, and the remainder is 1.6e-07.
