We're dividing 43568561 by 780 
We want to figure out the number of times 43568561 can be divided by 780.

Advancing to step 1:
The number 780 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 780

On to step 2:
When dividing 43 by 780, we get 0 with a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Bring next digit (5) of the dividend behind the 43 and repeat the process: 435 / 780

Going ahead to step 3:
435 divided by 780 is 0 with a remainder of 435.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 435, we end up with 435.
Fetch the next digit (6) from the dividend, attach it to 435 and continue: 4356 / 780

On to step 4:
780 goes into 4356 5 times with a remainder of 456.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 3900 from 4356 to get 456.
Bring next digit (8) of the dividend behind the 456 and repeat the process: 4568 / 780

Step 5:
780 can be fit into 4568 5 times, resulting in a remainder of 668.
Write down 5 as next digit of the result. 
Result so far: 55.0
Deduct 3900 from 4568 and we're left with 668.
Fetch the next digit (5) from the dividend, attach it to 668 and continue: 6685 / 780

Advancing to step 6:
780 goes into 6685 8 times with a remainder of 445.
The next digit of our result is 8. 
Result so far: 558.0
Subtract 6240 from 6685 to get 445.
Fetch the next digit (6) from the dividend, attach it to 445 and continue: 4456 / 780

Let's proceed to step 7:
4456 divided by 780 is 5 with a remainder of 556.
Record the quotient 5 as the next digit in the result. 
Result so far: 5585.0
Subtract 3900 from 4456 to get 556.
Include the next digit (1) from the dividend after 556, then repeat: 5561 / 780

Moving on to step 8:
If we divide 5561 by 780, we get 7 and a remainder of 101.
The next digit of our result is 7. 
Result so far: 55857.0
Subtracting 5460 from 5561 leaves us with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Advancing to step 9:
If we divide 1010 by 780, we get 1 and a remainder of 230.
The next digit of our result is 1. 
Result so far: 55857.1
If we subtract 780 from 1010, we get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Going ahead to step 10:
The number 780 fits into 2300 2 times, leaving a remainder of 740.
Use 2 as the next digit of our solution. 
Result so far: 55857.12
If we subtract 1560 from 2300, we get 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

On to step 11:
7400 divided by 780 is 9 with a remainder of 380.
The number 9 becomes the next digit in our result. 
Result so far: 55857.129
If we subtract 7020 from 7400, we get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

On to step 12:
3800 divided by 780 is 4 with a remainder of 680.
Put 4 as the next digit of the answer. 
Result so far: 55857.1294
Subtract 3120 from 3800 to get 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

On to step 13:
If we divide 6800 by 780, we get 8 and a remainder of 560.
Put 8 as the next digit of the answer. 
Result so far: 55857.12948
If we take 6240 away from 6800, we end up with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Let's proceed to step 14:
If we divide 5600 by 780, we get 7 and a remainder of 140.
Use 7 as the next digit of our solution. 
Result so far: 55857.129487
Subtract 5460 from 5600 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 15:
The number 780 fits into 1400 1 times, leaving a remainder of 620.
Record the quotient 1 as the next digit in the result. 
Result so far: 55857.1294871
Subtracting 780 from 1400 leaves us with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Advancing to step 16:
If we divide 6200 by 780, we get 7 and a remainder of 740.
Use 7 as the next digit of our solution. 
Result so far: 55857.12948717
Subtracting 5460 from 6200 leaves us with 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

The quotient of the division is 55857.12948717, and the remainder is 7.4e-07.
