We look at the division of 3475456 by 780 
We're looking to find how many times 780 goes into 3475456.

Moving on to step 1:
3 divided by 780 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 780

Advancing to step 2:
If we divide 34 by 780, we get 0 and a remainder of 34.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 34, we end up with 34.
Include the next digit (7) from the dividend after 34, then repeat: 347 / 780

On to step 3:
780 goes into 347 0 times with a remainder of 347.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 347, we end up with 347.
Bring next digit (5) of the dividend behind the 347 and repeat the process: 3475 / 780

On to step 4:
If we divide 3475 by 780, we get 4 and a remainder of 355.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 355 after subtracting 3120 from 3475.
Grab the next digit (4) from the dividend, add it to 355, then carry on: 3554 / 780

Advancing to step 5:
780 can be fit into 3554 4 times, resulting in a remainder of 434.
Write down 4 as next digit of the result. 
Result so far: 44.0
Deduct 3120 from 3554 and we're left with 434.
Take the next digit (5) from the dividend and append it to 434, then repeat: 4345 / 780

On to step 6:
The number 780 fits into 4345 5 times, leaving a remainder of 445.
The next digit of our result is 5. 
Result so far: 445.0
Deduct 3900 from 4345 and we're left with 445.
Take the next digit (6) from the dividend and append it to 445, then repeat: 4456 / 780

Step 7:
When dividing 4456 by 780, we get 5 with a remainder of 556.
The next digit of our result is 5. 
Result so far: 4455.0
Deduct 3900 from 4456 and we're left with 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Let's proceed to step 8:
If we divide 5560 by 780, we get 7 and a remainder of 100.
Use 7 as the next digit of our solution. 
Result so far: 4455.7
Subtracting 5460 from 5560 leaves us 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.

Moving on to step 9:
780 can be fit into 1000 1 times, resulting in a remainder of 220.
Record the quotient 1 as the next digit in the result. 
Result so far: 4455.71
The remainder is 220 after subtracting 780 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 10:
When dividing 2200 by 780, we get 2 with a remainder of 640.
The number 2 becomes the next digit in our result. 
Result so far: 4455.712
The remainder is 640 after subtracting 1560 from 2200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

On to step 11:
If we divide 6400 by 780, we get 8 and a remainder of 160.
The number 8 becomes the next digit in our result. 
Result so far: 4455.7128
If we subtract 6240 from 6400, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 12:
780 can be fit into 1600 2 times, resulting in a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 4455.71282
If we take 1560 away from 1600, 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.

Let's proceed to step 13:
When dividing 400 by 780, we get 0 with a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 4455.71282
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Advancing to step 14:
4000 divided by 780 is 5 with a remainder of 100.
Write down 5 as next digit of the result. 
Result so far: 4455.7128205
If we subtract 3900 from 4000, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 15:
780 goes into 1000 1 times with a remainder of 220.
Put 1 as the next digit of the answer. 
Result so far: 4455.71282051
If we subtract 780 from 1000, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

The final outcome is 4455.71282051, with a leftover of 2.2e-07.
