We look at the division of 17976781 by 158 
We want to figure out the number of times 17976781 can be divided by 158.

Moving on to step 1:
158 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 158

Moving on to step 2:
The number 158 fits into 17 0 times, leaving a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Bring next digit (9) of the dividend behind the 17 and repeat the process: 179 / 158

Step 3:
158 can be fit into 179 1 times, resulting in a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 158 from 179 and we're left with 21.
Include the next digit (7) from the dividend after 21, then repeat: 217 / 158

Going ahead to step 4:
158 goes into 217 1 times with a remainder of 59.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we subtract 158 from 217, we get 59.
Grab the next digit (6) from the dividend, add it to 59, then carry on: 596 / 158

Moving on to step 5:
The number 158 fits into 596 3 times, leaving a remainder of 122.
Record the quotient 3 as the next digit in the result. 
Result so far: 113.0
If we take 474 away from 596, we end up with 122.
Grab the next digit (7) from the dividend, add it to 122, then carry on: 1227 / 158

Going ahead to step 6:
If we divide 1227 by 158, we get 7 and a remainder of 121.
The next digit of our result is 7. 
Result so far: 1137.0
If we subtract 1106 from 1227, we get 121.
Fetch the next digit (8) from the dividend, attach it to 121 and continue: 1218 / 158

Moving on to step 7:
1218 divided by 158 is 7 with a remainder of 112.
Record the quotient 7 as the next digit in the result. 
Result so far: 11377.0
Deduct 1106 from 1218 and we're left with 112.
Append the next digit (1) from the dividend to 112 and continue with: 1121 / 158

Let's proceed to step 8:
1121 divided by 158 is 7 with a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 113777.0
If we take 1106 away from 1121, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 9:
158 goes into 150 0 times with a remainder of 150.
The next digit of our result is 0. 
Result so far: 113777.0
If we take 0 away from 150, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 10:
The number 158 fits into 1500 9 times, leaving a remainder of 78.
Put 9 as the next digit of the answer. 
Result so far: 113777.09
If we subtract 1422 from 1500, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 11:
158 goes into 780 4 times with a remainder of 148.
Use 4 as the next digit of our solution. 
Result so far: 113777.094
If we subtract 632 from 780, we get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

On to step 12:
If we divide 1480 by 158, we get 9 and a remainder of 58.
Use 9 as the next digit of our solution. 
Result so far: 113777.0949
The remainder is 58 after subtracting 1422 from 1480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 13:
158 can be fit into 580 3 times, resulting in a remainder of 106.
Write down 3 as next digit of the result. 
Result so far: 113777.09493
Subtracting 474 from 580 leaves us with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Moving on to step 14:
If we divide 1060 by 158, we get 6 and a remainder of 112.
Use 6 as the next digit of our solution. 
Result so far: 113777.094936
Subtract 948 from 1060 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Step 15:
When dividing 1120 by 158, we get 7 with a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 113777.0949367
Subtract 1106 from 1120 to 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.

Let's proceed to step 16:
If we divide 140 by 158, we get 0 and a remainder of 140.
The next digit of our result is 0. 
Result so far: 113777.0949367
Subtracting 0 from 140 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

The final outcome is 113777.0949367, with a leftover of 1.4e-07.
