Let's divide 78545714 by 257
We're looking to find how many times 257 goes into 78545714.

Let's proceed to step 1:
If we divide 7 by 257, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 257

Moving on to step 2:
257 goes into 78 0 times with a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Append the next digit (5) from the dividend to 78 and continue with: 785 / 257

Step 3:
257 can be fit into 785 3 times, resulting in a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 14 after subtracting 771 from 785.
Append the next digit (4) from the dividend to 14 and continue with: 144 / 257

Advancing to step 4:
144 divided by 257 is 0 with a remainder of 144.
Write down 0 as next digit of the result. 
Result so far: 30.0
Subtract 0 from 144 to get 144.
Fetch the next digit (5) from the dividend, attach it to 144 and continue: 1445 / 257

Step 5:
When dividing 1445 by 257, we get 5 with a remainder of 160.
Record the quotient 5 as the next digit in the result. 
Result so far: 305.0
If we subtract 1285 from 1445, we get 160.
Fetch the next digit (7) from the dividend, attach it to 160 and continue: 1607 / 257

Step 6:
1607 divided by 257 is 6 with a remainder of 65.
The next digit of our result is 6. 
Result so far: 3056.0
If we take 1542 away from 1607, we end up with 65.
Include the next digit (1) from the dividend after 65, then repeat: 651 / 257

Moving on to step 7:
If we divide 651 by 257, we get 2 and a remainder of 137.
Put 2 as the next digit of the answer. 
Result so far: 30562.0
Subtracting 514 from 651 leaves us with 137.
Take the next digit (4) from the dividend and append it to 137, then repeat: 1374 / 257

Advancing to step 8:
257 goes into 1374 5 times with a remainder of 89.
Use 5 as the next digit of our solution. 
Result so far: 305625.0
The remainder is 89 after subtracting 1285 from 1374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

On to step 9:
The number 257 fits into 890 3 times, leaving a remainder of 119.
Put 3 as the next digit of the answer. 
Result so far: 305625.3
The remainder is 119 after subtracting 771 from 890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Advancing to step 10:
If we divide 1190 by 257, we get 4 and a remainder of 162.
Use 4 as the next digit of our solution. 
Result so far: 305625.34
Deduct 1028 from 1190 and we're left with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Going ahead to step 11:
If we divide 1620 by 257, we get 6 and a remainder of 78.
The next digit of our result is 6. 
Result so far: 305625.346
If we subtract 1542 from 1620, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 12:
780 divided by 257 is 3 with a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 305625.3463
Deduct 771 from 780 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 13:
If we divide 90 by 257, we get 0 and a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 305625.3463
Deduct 0 from 90 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 14:
900 divided by 257 is 3 with a remainder of 129.
Record the quotient 3 as the next digit in the result. 
Result so far: 305625.346303
The remainder is 129 after subtracting 771 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

On to step 15:
When dividing 1290 by 257, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 305625.3463035
Subtracting 1285 from 1290 leaves us 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.

Moving on to step 16:
257 goes into 50 0 times with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 305625.3463035
Deduct 0 from 50 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.

Our division results in 305625.3463035 with a remaining 5e-08.
