Let's divide 80345069 by 156
We want to divide 80345069 by 156.

Step 1:
The number 156 fits into 8 0 times, leaving 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.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 156

Moving on to step 2:
The number 156 fits into 80 0 times, leaving a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Take the next digit (3) from the dividend and append it to 80, then repeat: 803 / 156

Step 3:
If we divide 803 by 156, we get 5 and a remainder of 23.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 780 away from 803, we end up with 23.
Fetch the next digit (4) from the dividend, attach it to 23 and continue: 234 / 156

On to step 4:
The number 156 fits into 234 1 times, leaving a remainder of 78.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
Subtracting 156 from 234 leaves us with 78.
Append the next digit (5) from the dividend to 78 and continue with: 785 / 156

Going ahead to step 5:
156 can be fit into 785 5 times, resulting in a remainder of 5.
The next digit of our result is 5. 
Result so far: 515.0
Subtracting 780 from 785 leaves us with 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 156

Let's proceed to step 6:
156 can be fit into 50 0 times, resulting in a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 5150.0
If we subtract 0 from 50, we get 50.
Bring next digit (6) of the dividend behind the 50 and repeat the process: 506 / 156

Moving on to step 7:
156 can be fit into 506 3 times, resulting in a remainder of 38.
Use 3 as the next digit of our solution. 
Result so far: 51503.0
Subtract 468 from 506 to get 38.
Bring next digit (9) of the dividend behind the 38 and repeat the process: 389 / 156

On to step 8:
If we divide 389 by 156, we get 2 and a remainder of 77.
The next digit of our result is 2. 
Result so far: 515032.0
The remainder is 77 after subtracting 312 from 389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 9:
770 divided by 156 is 4 with a remainder of 146.
The next digit of our result is 4. 
Result so far: 515032.4
Deduct 624 from 770 and we're left with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Moving on to step 10:
156 can be fit into 1460 9 times, resulting in a remainder of 56.
Put 9 as the next digit of the answer. 
Result so far: 515032.49
If we take 1404 away from 1460, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 11:
When dividing 560 by 156, we get 3 with a remainder of 92.
The next digit of our result is 3. 
Result so far: 515032.493
If we take 468 away from 560, we end up 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.

Advancing to step 12:
156 goes into 920 5 times with a remainder of 140.
Use 5 as the next digit of our solution. 
Result so far: 515032.4935
The remainder is 140 after subtracting 780 from 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 13:
The number 156 fits into 1400 8 times, leaving a remainder of 152.
Record the quotient 8 as the next digit in the result. 
Result so far: 515032.49358
The remainder is 152 after subtracting 1248 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Step 14:
If we divide 1520 by 156, we get 9 and a remainder of 116.
Record the quotient 9 as the next digit in the result. 
Result so far: 515032.493589
Subtracting 1404 from 1520 leaves us with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Let's proceed to step 15:
If we divide 1160 by 156, we get 7 and a remainder of 68.
The number 7 becomes the next digit in our result. 
Result so far: 515032.4935897
Deduct 1092 from 1160 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 16:
156 can be fit into 680 4 times, resulting in a remainder of 56.
Record the quotient 4 as the next digit in the result. 
Result so far: 515032.49358974
Deduct 624 from 680 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

After the division, we end up with 515032.49358974 and a remainder of 5.6e-08.
