We divide 343837 by 80
We're looking to find how many times 80 goes into 343837.

Going ahead to step 1:
The number 80 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 80

Let's proceed to step 2:
80 can be fit into 34 0 times, resulting in a remainder of 34.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 34 and we're left with 34.
Take the next digit (3) from the dividend and append it to 34, then repeat: 343 / 80

Moving on to step 3:
If we divide 343 by 80, we get 4 and a remainder of 23.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 320 from 343 and we're left with 23.
Bring next digit (8) of the dividend behind the 23 and repeat the process: 238 / 80

On to step 4:
If we divide 238 by 80, we get 2 and a remainder of 78.
Put 2 as the next digit of the answer. 
Result so far: 42.0
Deduct 160 from 238 and we're left with 78.
Include the next digit (3) from the dividend after 78, then repeat: 783 / 80

Going ahead to step 5:
The number 80 fits into 783 9 times, leaving a remainder of 63.
The number 9 becomes the next digit in our result. 
Result so far: 429.0
If we take 720 away from 783, we end up with 63.
Take the next digit (7) from the dividend and append it to 63, then repeat: 637 / 80

Going ahead to step 6:
637 divided by 80 is 7 with a remainder of 77.
The number 7 becomes the next digit in our result. 
Result so far: 4297.0
If we take 560 away from 637, we end up with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

On to step 7:
When dividing 770 by 80, we get 9 with a remainder of 50.
Record the quotient 9 as the next digit in the result. 
Result so far: 4297.9
If we subtract 720 from 770, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 8:
80 can be fit into 500 6 times, resulting in a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 4297.96
The remainder is 20 after subtracting 480 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
80 can be fit into 200 2 times, resulting in a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 4297.962
If we take 160 away from 200, 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.

Advancing to step 10:
80 can be fit into 400 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 4297.9625
Deduct 400 from 400 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 11:
0 divided by 80 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4297.9625
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 12:
When dividing 0 by 80, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4297.9625
If we take 0 away from 0, we end up with 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 outcome is 4297.9625, with a leftover of 0.0.
