4368421 divided by 389 
We want to figure out the number of times 4368421 can be divided by 389.

Step 1:
389 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 389

Going ahead to step 2:
If we divide 43 by 389, we get 0 and a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 43, we get 43.
Append the next digit (6) from the dividend to 43 and continue with: 436 / 389

Moving on to step 3:
If we divide 436 by 389, we get 1 and a remainder of 47.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 47 after subtracting 389 from 436.
Fetch the next digit (8) from the dividend, attach it to 47 and continue: 478 / 389

On to step 4:
If we divide 478 by 389, we get 1 and a remainder of 89.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we subtract 389 from 478, we get 89.
Grab the next digit (4) from the dividend, add it to 89, then carry on: 894 / 389

Step 5:
The number 389 fits into 894 2 times, leaving a remainder of 116.
Write down 2 as next digit of the result. 
Result so far: 112.0
Subtract 778 from 894 to get 116.
Fetch the next digit (2) from the dividend, attach it to 116 and continue: 1162 / 389

On to step 6:
389 can be fit into 1162 2 times, resulting in a remainder of 384.
The next digit of our result is 2. 
Result so far: 1122.0
The remainder is 384 after subtracting 778 from 1162.
Append the next digit (1) from the dividend to 384 and continue with: 3841 / 389

On to step 7:
The number 389 fits into 3841 9 times, leaving a remainder of 340.
Record the quotient 9 as the next digit in the result. 
Result so far: 11229.0
If we take 3501 away from 3841, we end up with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 8:
When dividing 3400 by 389, we get 8 with a remainder of 288.
The next digit of our result is 8. 
Result so far: 11229.8
Deduct 3112 from 3400 and we're left with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Let's proceed to step 9:
2880 divided by 389 is 7 with a remainder of 157.
Use 7 as the next digit of our solution. 
Result so far: 11229.87
Deduct 2723 from 2880 and we're left with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Let's proceed to step 10:
If we divide 1570 by 389, we get 4 and a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 11229.874
Deduct 1556 from 1570 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 11:
The number 389 fits into 140 0 times, leaving a remainder of 140.
Use 0 as the next digit of our solution. 
Result so far: 11229.874
If we take 0 away from 140, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 12:
389 can be fit into 1400 3 times, resulting in a remainder of 233.
The next digit of our result is 3. 
Result so far: 11229.87403
Subtracting 1167 from 1400 leaves us with 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Step 13:
389 goes into 2330 5 times with a remainder of 385.
Use 5 as the next digit of our solution. 
Result so far: 11229.874035
If we subtract 1945 from 2330, we get 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Step 14:
If we divide 3850 by 389, we get 9 and a remainder of 349.
Put 9 as the next digit of the answer. 
Result so far: 11229.8740359
If we take 3501 away from 3850, we end up with 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

Step 15:
If we divide 3490 by 389, we get 8 and a remainder of 378.
The next digit of our result is 8. 
Result so far: 11229.87403598
Subtracting 3112 from 3490 leaves us with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

In conclusion, the division gives 11229.87403598 with a balance of 3.78e-07.
