We divide 43420319 by 679
We want to figure out the number of times 43420319 can be divided by 679.

Advancing to step 1:
4 divided by 679 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 679

Moving on to step 2:
679 goes into 43 0 times with a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Include the next digit (4) from the dividend after 43, then repeat: 434 / 679

On to step 3:
679 goes into 434 0 times with a remainder of 434.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 434 leaves us with 434.
Grab the next digit (2) from the dividend, add it to 434, then carry on: 4342 / 679

Going ahead to step 4:
679 goes into 4342 6 times with a remainder of 268.
Write down 6 as next digit of the result. 
Result so far: 6.0
Deduct 4074 from 4342 and we're left with 268.
Append the next digit (0) from the dividend to 268 and continue with: 2680 / 679

Let's proceed to step 5:
679 can be fit into 2680 3 times, resulting in a remainder of 643.
Use 3 as the next digit of our solution. 
Result so far: 63.0
If we subtract 2037 from 2680, we get 643.
Take the next digit (3) from the dividend and append it to 643, then repeat: 6433 / 679

Moving on to step 6:
6433 divided by 679 is 9 with a remainder of 322.
Write down 9 as next digit of the result. 
Result so far: 639.0
Subtracting 6111 from 6433 leaves us with 322.
Append the next digit (1) from the dividend to 322 and continue with: 3221 / 679

Step 7:
679 can be fit into 3221 4 times, resulting in a remainder of 505.
The number 4 becomes the next digit in our result. 
Result so far: 6394.0
The remainder is 505 after subtracting 2716 from 3221.
Include the next digit (9) from the dividend after 505, then repeat: 5059 / 679

Advancing to step 8:
The number 679 fits into 5059 7 times, leaving a remainder of 306.
Write down 7 as next digit of the result. 
Result so far: 63947.0
Deduct 4753 from 5059 and we're left with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Advancing to step 9:
3060 divided by 679 is 4 with a remainder of 344.
The number 4 becomes the next digit in our result. 
Result so far: 63947.4
Deduct 2716 from 3060 and we're left with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Step 10:
When dividing 3440 by 679, we get 5 with a remainder of 45.
The next digit of our result is 5. 
Result so far: 63947.45
Subtracting 3395 from 3440 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 11:
679 can be fit into 450 0 times, resulting in a remainder of 450.
The next digit of our result is 0. 
Result so far: 63947.45
If we take 0 away from 450, we end up with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

On to step 12:
679 goes into 4500 6 times with a remainder of 426.
Record the quotient 6 as the next digit in the result. 
Result so far: 63947.4506
The remainder is 426 after subtracting 4074 from 4500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

Step 13:
4260 divided by 679 is 6 with a remainder of 186.
The number 6 becomes the next digit in our result. 
Result so far: 63947.45066
The remainder is 186 after subtracting 4074 from 4260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

In conclusion, the division gives 63947.45066 with a balance of 0.000186.
