78669407 divided by 389 
We want to figure out the number of times 78669407 can be divided by 389.

Step 1:
When dividing 7 by 389, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 389

Step 2:
78 divided by 389 is 0 with a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Include the next digit (6) from the dividend after 78, then repeat: 786 / 389

Going ahead to step 3:
When dividing 786 by 389, we get 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 778 from 786 leaves us with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 389

Step 4:
When dividing 86 by 389, we get 0 with a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 20.0
If we subtract 0 from 86, we get 86.
Take the next digit (9) from the dividend and append it to 86, then repeat: 869 / 389

Moving on to step 5:
When dividing 869 by 389, we get 2 with a remainder of 91.
Write down 2 as next digit of the result. 
Result so far: 202.0
Subtracting 778 from 869 leaves us with 91.
Grab the next digit (4) from the dividend, add it to 91, then carry on: 914 / 389

Moving on to step 6:
914 divided by 389 is 2 with a remainder of 136.
Put 2 as the next digit of the answer. 
Result so far: 2022.0
Subtracting 778 from 914 leaves us with 136.
Grab the next digit (0) from the dividend, add it to 136, then carry on: 1360 / 389

On to step 7:
389 can be fit into 1360 3 times, resulting in a remainder of 193.
The next digit of our result is 3. 
Result so far: 20223.0
If we subtract 1167 from 1360, we get 193.
Grab the next digit (7) from the dividend, add it to 193, then carry on: 1937 / 389

Moving on to step 8:
When dividing 1937 by 389, we get 4 with a remainder of 381.
Record the quotient 4 as the next digit in the result. 
Result so far: 202234.0
Subtracting 1556 from 1937 leaves us with 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

Moving on to step 9:
The number 389 fits into 3810 9 times, leaving a remainder of 309.
Write down 9 as next digit of the result. 
Result so far: 202234.9
The remainder is 309 after subtracting 3501 from 3810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Moving on to step 10:
The number 389 fits into 3090 7 times, leaving a remainder of 367.
The number 7 becomes the next digit in our result. 
Result so far: 202234.97
Subtracting 2723 from 3090 leaves us with 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

Step 11:
If we divide 3670 by 389, we get 9 and a remainder of 169.
The next digit of our result is 9. 
Result so far: 202234.979
The remainder is 169 after subtracting 3501 from 3670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Moving on to step 12:
If we divide 1690 by 389, we get 4 and a remainder of 134.
Use 4 as the next digit of our solution. 
Result so far: 202234.9794
The remainder is 134 after subtracting 1556 from 1690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Going ahead to step 13:
1340 divided by 389 is 3 with a remainder of 173.
The next digit of our result is 3. 
Result so far: 202234.97943
If we take 1167 away from 1340, we end up with 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

On to step 14:
If we divide 1730 by 389, we get 4 and a remainder of 174.
Write down 4 as next digit of the result. 
Result so far: 202234.979434
The remainder is 174 after subtracting 1556 from 1730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Let's proceed to step 15:
The number 389 fits into 1740 4 times, leaving a remainder of 184.
The next digit of our result is 4. 
Result so far: 202234.9794344
Subtract 1556 from 1740 to get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

The quotient of the division is 202234.9794344, and the remainder is 1.84e-06.
