We look at the division of 81909244 by 156 
We want to figure out the number of times 81909244 can be divided by 156.

Moving on to step 1:
When dividing 8 by 156, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 156

On to step 2:
The number 156 fits into 81 0 times, leaving a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Append the next digit (9) from the dividend to 81 and continue with: 819 / 156

Step 3:
819 divided by 156 is 5 with a remainder of 39.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we subtract 780 from 819, we get 39.
Append the next digit (0) from the dividend to 39 and continue with: 390 / 156

On to step 4:
If we divide 390 by 156, we get 2 and a remainder of 78.
The next digit of our result is 2. 
Result so far: 52.0
Subtracting 312 from 390 leaves us with 78.
Fetch the next digit (9) from the dividend, attach it to 78 and continue: 789 / 156

On to step 5:
When dividing 789 by 156, we get 5 with a remainder of 9.
Put 5 as the next digit of the answer. 
Result so far: 525.0
Subtract 780 from 789 to get 9.
Grab the next digit (2) from the dividend, add it to 9, then carry on: 92 / 156

Step 6:
If we divide 92 by 156, we get 0 and a remainder of 92.
Put 0 as the next digit of the answer. 
Result so far: 5250.0
If we subtract 0 from 92, we get 92.
Grab the next digit (4) from the dividend, add it to 92, then carry on: 924 / 156

Step 7:
156 goes into 924 5 times with a remainder of 144.
Write down 5 as next digit of the result. 
Result so far: 52505.0
If we take 780 away from 924, we end up with 144.
Append the next digit (4) from the dividend to 144 and continue with: 1444 / 156

On to step 8:
The number 156 fits into 1444 9 times, leaving a remainder of 40.
The next digit of our result is 9. 
Result so far: 525059.0
If we take 1404 away from 1444, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 9:
156 can be fit into 400 2 times, resulting in a remainder of 88.
Write down 2 as next digit of the result. 
Result so far: 525059.2
If we take 312 away from 400, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 10:
880 divided by 156 is 5 with a remainder of 100.
Put 5 as the next digit of the answer. 
Result so far: 525059.25
Deduct 780 from 880 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 11:
156 goes into 1000 6 times with a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 525059.256
If we subtract 936 from 1000, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 12:
The number 156 fits into 640 4 times, leaving a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 525059.2564
Subtracting 624 from 640 leaves us with 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 13:
156 can be fit into 160 1 times, resulting in a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 525059.25641
Deduct 156 from 160 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 14:
156 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 525059.25641
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 15:
400 divided by 156 is 2 with a remainder of 88.
Put 2 as the next digit of the answer. 
Result so far: 525059.2564102
The remainder is 88 after subtracting 312 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Going ahead to step 16:
If we divide 880 by 156, we get 5 and a remainder of 100.
Write down 5 as next digit of the result. 
Result so far: 525059.25641025
The remainder is 100 after subtracting 780 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final outcome is 525059.25641025, with a leftover of 1e-07.
