We're dividing 81738663 by 158 
We want to divide 81738663 by 158.

Step 1:
If we divide 8 by 158, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 158

Going ahead to step 2:
158 can be fit into 81 0 times, resulting in a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Fetch the next digit (7) from the dividend, attach it to 81 and continue: 817 / 158

Let's proceed to step 3:
When dividing 817 by 158, we get 5 with a remainder of 27.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 790 from 817, we get 27.
Bring next digit (3) of the dividend behind the 27 and repeat the process: 273 / 158

Let's proceed to step 4:
When dividing 273 by 158, we get 1 with a remainder of 115.
Put 1 as the next digit of the answer. 
Result so far: 51.0
The remainder is 115 after subtracting 158 from 273.
Grab the next digit (8) from the dividend, add it to 115, then carry on: 1158 / 158

Going ahead to step 5:
1158 divided by 158 is 7 with a remainder of 52.
Record the quotient 7 as the next digit in the result. 
Result so far: 517.0
The remainder is 52 after subtracting 1106 from 1158.
Fetch the next digit (6) from the dividend, attach it to 52 and continue: 526 / 158

Let's proceed to step 6:
158 goes into 526 3 times with a remainder of 52.
The next digit of our result is 3. 
Result so far: 5173.0
Subtract 474 from 526 to get 52.
Grab the next digit (6) from the dividend, add it to 52, then carry on: 526 / 158

On to step 7:
When dividing 526 by 158, we get 3 with a remainder of 52.
Record the quotient 3 as the next digit in the result. 
Result so far: 51733.0
Subtract 474 from 526 to get 52.
Fetch the next digit (3) from the dividend, attach it to 52 and continue: 523 / 158

On to step 8:
158 goes into 523 3 times with a remainder of 49.
The number 3 becomes the next digit in our result. 
Result so far: 517333.0
Subtract 474 from 523 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 9:
490 divided by 158 is 3 with a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 517333.3
If we subtract 474 from 490, 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.

Advancing to step 10:
158 can be fit into 160 1 times, resulting in a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 517333.31
If we take 158 away from 160, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 11:
158 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 517333.31
Deduct 0 from 20 and we're left 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.

Going ahead to step 12:
If we divide 200 by 158, we get 1 and a remainder of 42.
Write down 1 as next digit of the result. 
Result so far: 517333.3101
The remainder is 42 after subtracting 158 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 13:
158 can be fit into 420 2 times, resulting in a remainder of 104.
Put 2 as the next digit of the answer. 
Result so far: 517333.31012
If we take 316 away from 420, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Going ahead to step 14:
158 can be fit into 1040 6 times, resulting in a remainder of 92.
Use 6 as the next digit of our solution. 
Result so far: 517333.310126
Subtracting 948 from 1040 leaves us with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Moving on to step 15:
920 divided by 158 is 5 with a remainder of 130.
Use 5 as the next digit of our solution. 
Result so far: 517333.3101265
Deduct 790 from 920 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 16:
158 can be fit into 1300 8 times, resulting in a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 517333.31012658
Deduct 1264 from 1300 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

After the division, we end up with 517333.31012658 and a remainder of 3.6e-08.
