80635710 ÷ 158 
We want to figure out the number of times 80635710 can be divided by 158.

Going ahead to step 1:
When dividing 8 by 158, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 158

Moving on to step 2:
158 can be fit into 80 0 times, resulting in a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Include the next digit (6) from the dividend after 80, then repeat: 806 / 158

Advancing to step 3:
When dividing 806 by 158, we get 5 with a remainder of 16.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 790 from 806 and we're left with 16.
Take the next digit (3) from the dividend and append it to 16, then repeat: 163 / 158

Advancing to step 4:
163 divided by 158 is 1 with a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 51.0
If we subtract 158 from 163, we get 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 158

Going ahead to step 5:
The number 158 fits into 55 0 times, leaving a remainder of 55.
The next digit of our result is 0. 
Result so far: 510.0
Deduct 0 from 55 and we're left with 55.
Fetch the next digit (7) from the dividend, attach it to 55 and continue: 557 / 158

Let's proceed to step 6:
If we divide 557 by 158, we get 3 and a remainder of 83.
Write down 3 as next digit of the result. 
Result so far: 5103.0
Deduct 474 from 557 and we're left with 83.
Fetch the next digit (1) from the dividend, attach it to 83 and continue: 831 / 158

Let's proceed to step 7:
831 divided by 158 is 5 with a remainder of 41.
The next digit of our result is 5. 
Result so far: 51035.0
Subtracting 790 from 831 leaves us with 41.
Grab the next digit (0) from the dividend, add it to 41, then carry on: 410 / 158

Step 8:
158 can be fit into 410 2 times, resulting in a remainder of 94.
The next digit of our result is 2. 
Result so far: 510352.0
If we subtract 316 from 410, we get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Moving on to step 9:
The number 158 fits into 940 5 times, leaving a remainder of 150.
Write down 5 as next digit of the result. 
Result so far: 510352.5
If we subtract 790 from 940, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 10:
The number 158 fits into 1500 9 times, leaving a remainder of 78.
The number 9 becomes the next digit in our result. 
Result so far: 510352.59
Subtract 1422 from 1500 to 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.

Let's proceed 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: 510352.594
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.

Step 12:
If we divide 1480 by 158, we get 9 and a remainder of 58.
The next digit of our result is 9. 
Result so far: 510352.5949
Deduct 1422 from 1480 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 13:
If we divide 580 by 158, we get 3 and a remainder of 106.
Write down 3 as next digit of the result. 
Result so far: 510352.59493
Subtract 474 from 580 to get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Let's proceed to step 14:
158 can be fit into 1060 6 times, resulting in a remainder of 112.
Put 6 as the next digit of the answer. 
Result so far: 510352.594936
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.

On to step 15:
The number 158 fits into 1120 7 times, leaving a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 510352.5949367
If we subtract 1106 from 1120, 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 16:
If we divide 140 by 158, we get 0 and a remainder of 140.
The number 0 becomes the next digit in our result. 
Result so far: 510352.5949367
Deduct 0 from 140 and we're left 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.

After the division, we end up with 510352.5949367 and a remainder of 1.4e-07.
