We divide 3430673 by 800
Let's see how many times 800 fits into 3430673.

Let's proceed to step 1:
3 divided by 800 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 800

Moving on to step 2:
The number 800 fits into 34 0 times, leaving 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.
Fetch the next digit (3) from the dividend, attach it to 34 and continue: 343 / 800

Advancing to step 3:
800 can be fit into 343 0 times, resulting in a remainder of 343.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 343 leaves us with 343.
Grab the next digit (0) from the dividend, add it to 343, then carry on: 3430 / 800

Going ahead to step 4:
800 can be fit into 3430 4 times, resulting in a remainder of 230.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 3200 from 3430 to get 230.
Append the next digit (6) from the dividend to 230 and continue with: 2306 / 800

Advancing to step 5:
800 goes into 2306 2 times with a remainder of 706.
The next digit of our result is 2. 
Result so far: 42.0
Subtracting 1600 from 2306 leaves us with 706.
Grab the next digit (7) from the dividend, add it to 706, then carry on: 7067 / 800

Moving on to step 6:
800 goes into 7067 8 times with a remainder of 667.
The next digit of our result is 8. 
Result so far: 428.0
The remainder is 667 after subtracting 6400 from 7067.
Fetch the next digit (3) from the dividend, attach it to 667 and continue: 6673 / 800

Advancing to step 7:
800 can be fit into 6673 8 times, resulting in a remainder of 273.
Use 8 as the next digit of our solution. 
Result so far: 4288.0
Subtract 6400 from 6673 to get 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

Advancing to step 8:
800 goes into 2730 3 times with a remainder of 330.
Write down 3 as next digit of the result. 
Result so far: 4288.3
Deduct 2400 from 2730 and we're left with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Going ahead to step 9:
The number 800 fits into 3300 4 times, leaving a remainder of 100.
The next digit of our result is 4. 
Result so far: 4288.34
If we take 3200 away from 3300, we end up 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.

Advancing to step 10:
1000 divided by 800 is 1 with a remainder of 200.
Put 1 as the next digit of the answer. 
Result so far: 4288.341
Subtract 800 from 1000 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 11:
When dividing 2000 by 800, we get 2 with a remainder of 400.
Use 2 as the next digit of our solution. 
Result so far: 4288.3412
Subtracting 1600 from 2000 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 12:
4000 divided by 800 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 4288.34125
Subtract 4000 from 4000 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 13:
If we divide 0 by 800, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 4288.34125
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 14:
When dividing 0 by 800, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 4288.34125
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 4288.34125 with a remainder of 0.0.
