3407456 ÷ 785 
Our goal is to divide 3407456 by 785.

Step 1:
3 divided by 785 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 785

Moving on to step 2:
34 divided by 785 is 0 with a remainder of 34.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 34, we get 34.
Fetch the next digit (0) from the dividend, attach it to 34 and continue: 340 / 785

Let's proceed to step 3:
When dividing 340 by 785, we get 0 with a remainder of 340.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 340 to get 340.
Take the next digit (7) from the dividend and append it to 340, then repeat: 3407 / 785

Step 4:
The number 785 fits into 3407 4 times, leaving a remainder of 267.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 3140 away from 3407, we end up with 267.
Append the next digit (4) from the dividend to 267 and continue with: 2674 / 785

Step 5:
785 goes into 2674 3 times with a remainder of 319.
Put 3 as the next digit of the answer. 
Result so far: 43.0
Subtracting 2355 from 2674 leaves us with 319.
Append the next digit (5) from the dividend to 319 and continue with: 3195 / 785

Step 6:
785 can be fit into 3195 4 times, resulting in a remainder of 55.
The next digit of our result is 4. 
Result so far: 434.0
Subtract 3140 from 3195 to get 55.
Take the next digit (6) from the dividend and append it to 55, then repeat: 556 / 785

Going ahead to step 7:
If we divide 556 by 785, we get 0 and a remainder of 556.
The next digit of our result is 0. 
Result so far: 4340.0
Subtracting 0 from 556 leaves us 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.

Advancing to step 8:
785 can be fit into 5560 7 times, resulting in a remainder of 65.
The next digit of our result is 7. 
Result so far: 4340.7
The remainder is 65 after subtracting 5495 from 5560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 9:
785 goes into 650 0 times with a remainder of 650.
Write down 0 as next digit of the result. 
Result so far: 4340.7
Subtracting 0 from 650 leaves us with 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Step 10:
6500 divided by 785 is 8 with a remainder of 220.
Put 8 as the next digit of the answer. 
Result so far: 4340.708
Deduct 6280 from 6500 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 11:
If we divide 2200 by 785, we get 2 and a remainder of 630.
Use 2 as the next digit of our solution. 
Result so far: 4340.7082
If we subtract 1570 from 2200, we get 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Going ahead to step 12:
The number 785 fits into 6300 8 times, leaving a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 4340.70828
If we subtract 6280 from 6300, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 13:
785 can be fit into 200 0 times, resulting in a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 4340.70828
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 14:
2000 divided by 785 is 2 with a remainder of 430.
Record the quotient 2 as the next digit in the result. 
Result so far: 4340.7082802
If we subtract 1570 from 2000, we get 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Step 15:
When dividing 4300 by 785, we get 5 with a remainder of 375.
The number 5 becomes the next digit in our result. 
Result so far: 4340.70828025
If we take 3925 away from 4300, we end up with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

The final outcome is 4340.70828025, with a leftover of 3.75e-07.
