Let's divide 78117889 by 156
We're looking to find how many times 156 goes into 78117889.

Going ahead to step 1:
156 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 156

Let's proceed to step 2:
When dividing 78 by 156, we get 0 with a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Take the next digit (1) from the dividend and append it to 78, then repeat: 781 / 156

Step 3:
156 can be fit into 781 5 times, resulting in a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 780 from 781 leaves us with 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 156

On to step 4:
When dividing 11 by 156, we get 0 with a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 50.0
Subtracting 0 from 11 leaves us with 11.
Append the next digit (7) from the dividend to 11 and continue with: 117 / 156

Step 5:
When dividing 117 by 156, we get 0 with a remainder of 117.
Put 0 as the next digit of the answer. 
Result so far: 500.0
If we subtract 0 from 117, we get 117.
Bring next digit (8) of the dividend behind the 117 and repeat the process: 1178 / 156

Moving on to step 6:
When dividing 1178 by 156, we get 7 with a remainder of 86.
The next digit of our result is 7. 
Result so far: 5007.0
Deduct 1092 from 1178 and we're left with 86.
Bring next digit (8) of the dividend behind the 86 and repeat the process: 868 / 156

Moving on to step 7:
868 divided by 156 is 5 with a remainder of 88.
The next digit of our result is 5. 
Result so far: 50075.0
Subtract 780 from 868 to get 88.
Fetch the next digit (9) from the dividend, attach it to 88 and continue: 889 / 156

Going ahead to step 8:
When dividing 889 by 156, we get 5 with a remainder of 109.
The next digit of our result is 5. 
Result so far: 500755.0
The remainder is 109 after subtracting 780 from 889.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Step 9:
The number 156 fits into 1090 6 times, leaving a remainder of 154.
Put 6 as the next digit of the answer. 
Result so far: 500755.6
The remainder is 154 after subtracting 936 from 1090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Moving on to step 10:
1540 divided by 156 is 9 with a remainder of 136.
The number 9 becomes the next digit in our result. 
Result so far: 500755.69
The remainder is 136 after subtracting 1404 from 1540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Moving on to step 11:
The number 156 fits into 1360 8 times, leaving a remainder of 112.
The number 8 becomes the next digit in our result. 
Result so far: 500755.698
If we take 1248 away from 1360, we end up with 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 12:
1120 divided by 156 is 7 with a remainder of 28.
The number 7 becomes the next digit in our result. 
Result so far: 500755.6987
Subtracting 1092 from 1120 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 13:
280 divided by 156 is 1 with a remainder of 124.
The next digit of our result is 1. 
Result so far: 500755.69871
If we subtract 156 from 280, we get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

On to step 14:
156 can be fit into 1240 7 times, resulting in a remainder of 148.
Write down 7 as next digit of the result. 
Result so far: 500755.698717
Deduct 1092 from 1240 and we're left with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Moving on to step 15:
156 can be fit into 1480 9 times, resulting in a remainder of 76.
Write down 9 as next digit of the result. 
Result so far: 500755.6987179
Deduct 1404 from 1480 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 16:
156 goes into 760 4 times with a remainder of 136.
The next digit of our result is 4. 
Result so far: 500755.69871794
Deduct 624 from 760 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

The final outcome is 500755.69871794, with a leftover of 1.36e-07.
