351551 divided by 78 
Let's see how many times 78 fits into 351551.

Step 1:
If we divide 3 by 78, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 78

Going ahead to step 2:
78 can be fit into 35 0 times, resulting in a remainder of 35.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 35 and we're left with 35.
Take the next digit (1) from the dividend and append it to 35, then repeat: 351 / 78

Let's proceed to step 3:
If we divide 351 by 78, we get 4 and a remainder of 39.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 312 from 351 to get 39.
Bring next digit (5) of the dividend behind the 39 and repeat the process: 395 / 78

Let's proceed to step 4:
When dividing 395 by 78, we get 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 45.0
Subtracting 390 from 395 leaves us with 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 78

Let's proceed to step 5:
78 goes into 55 0 times with a remainder of 55.
The next digit of our result is 0. 
Result so far: 450.0
Deduct 0 from 55 and we're left with 55.
Grab the next digit (1) from the dividend, add it to 55, then carry on: 551 / 78

Advancing to step 6:
When dividing 551 by 78, we get 7 with a remainder of 5.
The next digit of our result is 7. 
Result so far: 4507.0
If we take 546 away from 551, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 7:
If we divide 50 by 78, we get 0 and a remainder of 50.
The next digit of our result is 0. 
Result so far: 4507.0
If we subtract 0 from 50, 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.

Moving on to step 8:
The number 78 fits into 500 6 times, leaving a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 4507.06
Subtracting 468 from 500 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 9:
78 goes into 320 4 times with a remainder of 8.
The next digit of our result is 4. 
Result so far: 4507.064
Deduct 312 from 320 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
78 goes into 80 1 times with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 4507.0641
The remainder is 2 after subtracting 78 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 11:
If we divide 20 by 78, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 4507.0641
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 12:
If we divide 200 by 78, we get 2 and a remainder of 44.
Write down 2 as next digit of the result. 
Result so far: 4507.064102
Deduct 156 from 200 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 13:
When dividing 440 by 78, we get 5 with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 4507.0641025
Deduct 390 from 440 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 14:
The number 78 fits into 500 6 times, leaving a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 4507.06410256
Subtract 468 from 500 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 4507.06410256 and a remainder of 3.2e-08.
