Let's divide 9143457 by 780
We want to divide 9143457 by 780.

Let's proceed to step 1:
When dividing 9 by 780, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 780

Going ahead to step 2:
If we divide 91 by 780, we get 0 and a remainder of 91.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 91 after subtracting 0 from 91.
Take the next digit (4) from the dividend and append it to 91, then repeat: 914 / 780

Moving on to step 3:
780 goes into 914 1 times with a remainder of 134.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 134 after subtracting 780 from 914.
Take the next digit (3) from the dividend and append it to 134, then repeat: 1343 / 780

Going ahead to step 4:
780 goes into 1343 1 times with a remainder of 563.
The next digit of our result is 1. 
Result so far: 11.0
Deduct 780 from 1343 and we're left with 563.
Append the next digit (4) from the dividend to 563 and continue with: 5634 / 780

Moving on to step 5:
When dividing 5634 by 780, we get 7 with a remainder of 174.
Write down 7 as next digit of the result. 
Result so far: 117.0
Deduct 5460 from 5634 and we're left with 174.
Fetch the next digit (5) from the dividend, attach it to 174 and continue: 1745 / 780

Moving on to step 6:
780 can be fit into 1745 2 times, resulting in a remainder of 185.
Put 2 as the next digit of the answer. 
Result so far: 1172.0
The remainder is 185 after subtracting 1560 from 1745.
Grab the next digit (7) from the dividend, add it to 185, then carry on: 1857 / 780

On to step 7:
When dividing 1857 by 780, we get 2 with a remainder of 297.
The next digit of our result is 2. 
Result so far: 11722.0
If we take 1560 away from 1857, we end up with 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

Moving on to step 8:
2970 divided by 780 is 3 with a remainder of 630.
Use 3 as the next digit of our solution. 
Result so far: 11722.3
Deduct 2340 from 2970 and we're left with 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Step 9:
When dividing 6300 by 780, we get 8 with a remainder of 60.
The number 8 becomes the next digit in our result. 
Result so far: 11722.38
If we take 6240 away from 6300, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 10:
If we divide 600 by 780, we get 0 and a remainder of 600.
The number 0 becomes the next digit in our result. 
Result so far: 11722.38
If we take 0 away from 600, we end up with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

On to step 11:
780 can be fit into 6000 7 times, resulting in a remainder of 540.
Write down 7 as next digit of the result. 
Result so far: 11722.3807
Deduct 5460 from 6000 and we're left with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Let's proceed to step 12:
780 can be fit into 5400 6 times, resulting in a remainder of 720.
The next digit of our result is 6. 
Result so far: 11722.38076
If we take 4680 away from 5400, we end up with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Step 13:
7200 divided by 780 is 9 with a remainder of 180.
Put 9 as the next digit of the answer. 
Result so far: 11722.380769
If we take 7020 away from 7200, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 14:
1800 divided by 780 is 2 with a remainder of 240.
Write down 2 as next digit of the result. 
Result so far: 11722.3807692
Subtract 1560 from 1800 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 15:
The number 780 fits into 2400 3 times, leaving a remainder of 60.
The next digit of our result is 3. 
Result so far: 11722.38076923
The remainder is 60 after subtracting 2340 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

After the division, we end up with 11722.38076923 and a remainder of 6e-08.
