76624389 ÷ 257 
Let's see how many times 257 fits into 76624389.

Advancing 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.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 257

On to step 2:
76 divided by 257 is 0 with a remainder of 76.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 76 and we're left with 76.
Include the next digit (6) from the dividend after 76, then repeat: 766 / 257

Advancing to step 3:
257 goes into 766 2 times with a remainder of 252.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 514 from 766 to get 252.
Take the next digit (2) from the dividend and append it to 252, then repeat: 2522 / 257

Let's proceed to step 4:
2522 divided by 257 is 9 with a remainder of 209.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
Subtract 2313 from 2522 to get 209.
Grab the next digit (4) from the dividend, add it to 209, then carry on: 2094 / 257

Step 5:
257 goes into 2094 8 times with a remainder of 38.
Record the quotient 8 as the next digit in the result. 
Result so far: 298.0
Deduct 2056 from 2094 and we're left with 38.
Fetch the next digit (3) from the dividend, attach it to 38 and continue: 383 / 257

Let's proceed to step 6:
383 divided by 257 is 1 with a remainder of 126.
Record the quotient 1 as the next digit in the result. 
Result so far: 2981.0
Subtracting 257 from 383 leaves us with 126.
Bring next digit (8) of the dividend behind the 126 and repeat the process: 1268 / 257

Moving on to step 7:
257 goes into 1268 4 times with a remainder of 240.
The number 4 becomes the next digit in our result. 
Result so far: 29814.0
Subtract 1028 from 1268 to get 240.
Bring next digit (9) of the dividend behind the 240 and repeat the process: 2409 / 257

On to step 8:
When dividing 2409 by 257, we get 9 with a remainder of 96.
The next digit of our result is 9. 
Result so far: 298149.0
Subtracting 2313 from 2409 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 9:
The number 257 fits into 960 3 times, leaving a remainder of 189.
The number 3 becomes the next digit in our result. 
Result so far: 298149.3
Subtracting 771 from 960 leaves us with 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Step 10:
1890 divided by 257 is 7 with a remainder of 91.
Use 7 as the next digit of our solution. 
Result so far: 298149.37
Subtract 1799 from 1890 to get 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

On to step 11:
910 divided by 257 is 3 with a remainder of 139.
Record the quotient 3 as the next digit in the result. 
Result so far: 298149.373
If we subtract 771 from 910, we get 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Moving on to step 12:
1390 divided by 257 is 5 with a remainder of 105.
The number 5 becomes the next digit in our result. 
Result so far: 298149.3735
Subtract 1285 from 1390 to get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Moving on to step 13:
If we divide 1050 by 257, we get 4 and a remainder of 22.
Write down 4 as next digit of the result. 
Result so far: 298149.37354
If we subtract 1028 from 1050, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 14:
When dividing 220 by 257, we get 0 with a remainder of 220.
Write down 0 as next digit of the result. 
Result so far: 298149.37354
Deduct 0 from 220 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 15:
257 can be fit into 2200 8 times, resulting in a remainder of 144.
Use 8 as the next digit of our solution. 
Result so far: 298149.3735408
Deduct 2056 from 2200 and we're left with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Let's proceed to step 16:
1440 divided by 257 is 5 with a remainder of 155.
The number 5 becomes the next digit in our result. 
Result so far: 298149.37354085
If we take 1285 away from 1440, we end up with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

In conclusion, the division gives 298149.37354085 with a balance of 1.55e-07.
