Our goal is to divide 74003867 by 343.

Advancing to step 1:
7 divided by 343 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 343

On to step 2:
The number 343 fits into 74 0 times, leaving a remainder of 74.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 74 to get 74.
Grab the next digit (0) from the dividend, add it to 74, then carry on: 740 / 343

Step 3:
343 can be fit into 740 2 times, resulting in a remainder of 54.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 686 from 740 and we're left with 54.
Include the next digit (0) from the dividend after 54, then repeat: 540 / 343

On to step 4:
540 divided by 343 is 1 with a remainder of 197.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
The remainder is 197 after subtracting 343 from 540.
Take the next digit (3) from the dividend and append it to 197, then repeat: 1973 / 343

Going ahead to step 5:
If we divide 1973 by 343, we get 5 and a remainder of 258.
The next digit of our result is 5. 
Result so far: 215.0
If we subtract 1715 from 1973, we get 258.
Append the next digit (8) from the dividend to 258 and continue with: 2588 / 343

Advancing to step 6:
The number 343 fits into 2588 7 times, leaving a remainder of 187.
The next digit of our result is 7. 
Result so far: 2157.0
If we take 2401 away from 2588, we end up with 187.
Append the next digit (6) from the dividend to 187 and continue with: 1876 / 343

Advancing to step 7:
343 goes into 1876 5 times with a remainder of 161.
The next digit of our result is 5. 
Result so far: 21575.0
If we take 1715 away from 1876, we end up with 161.
Bring next digit (7) of the dividend behind the 161 and repeat the process: 1617 / 343

Step 8:
The number 343 fits into 1617 4 times, leaving a remainder of 245.
The number 4 becomes the next digit in our result. 
Result so far: 215754.0
If we subtract 1372 from 1617, we get 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Going ahead to step 9:
2450 divided by 343 is 7 with a remainder of 49.
Use 7 as the next digit of our solution. 
Result so far: 215754.7
Deduct 2401 from 2450 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 10:
343 can be fit into 490 1 times, resulting in a remainder of 147.
Write down 1 as next digit of the result. 
Result so far: 215754.71
Deduct 343 from 490 and we're left with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Advancing to step 11:
The number 343 fits into 1470 4 times, leaving a remainder of 98.
Write down 4 as next digit of the result. 
Result so far: 215754.714
Deduct 1372 from 1470 and we're left with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Moving on to step 12:
If we divide 980 by 343, we get 2 and a remainder of 294.
The number 2 becomes the next digit in our result. 
Result so far: 215754.7142
Subtracting 686 from 980 leaves us with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Going ahead to step 13:
343 can be fit into 2940 8 times, resulting in a remainder of 196.
Use 8 as the next digit of our solution. 
Result so far: 215754.71428
Deduct 2744 from 2940 and we're left with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Going ahead to step 14:
343 can be fit into 1960 5 times, resulting in a remainder of 245.
Put 5 as the next digit of the answer. 
Result so far: 215754.714285
Deduct 1715 from 1960 and we're left with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

On to step 15:
2450 divided by 343 is 7 with a remainder of 49.
The next digit of our result is 7. 
Result so far: 215754.7142857
If we subtract 2401 from 2450, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 16:
The number 343 fits into 490 1 times, leaving a remainder of 147.
Put 1 as the next digit of the answer. 
Result so far: 215754.71428571
Subtract 343 from 490 to get 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

The final result is 215754.71428571 with a remainder of 1.47e-07.
