78407117 divided by 257 
We're looking to find how many times 257 goes into 78407117.

Advancing to step 1:
7 divided by 257 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 257

Step 2:
When dividing 78 by 257, we get 0 with a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Bring next digit (4) of the dividend behind the 78 and repeat the process: 784 / 257

Going ahead to step 3:
The number 257 fits into 784 3 times, leaving a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 771 from 784 leaves us with 13.
Fetch the next digit (0) from the dividend, attach it to 13 and continue: 130 / 257

Step 4:
If we divide 130 by 257, we get 0 and a remainder of 130.
Write down 0 as next digit of the result. 
Result so far: 30.0
If we subtract 0 from 130, we get 130.
Include the next digit (7) from the dividend after 130, then repeat: 1307 / 257

Advancing to step 5:
When dividing 1307 by 257, we get 5 with a remainder of 22.
Record the quotient 5 as the next digit in the result. 
Result so far: 305.0
Deduct 1285 from 1307 and we're left with 22.
Include the next digit (1) from the dividend after 22, then repeat: 221 / 257

Let's proceed to step 6:
When dividing 221 by 257, we get 0 with a remainder of 221.
Write down 0 as next digit of the result. 
Result so far: 3050.0
The remainder is 221 after subtracting 0 from 221.
Grab the next digit (1) from the dividend, add it to 221, then carry on: 2211 / 257

Advancing to step 7:
257 goes into 2211 8 times with a remainder of 155.
The number 8 becomes the next digit in our result. 
Result so far: 30508.0
If we take 2056 away from 2211, we end up with 155.
Include the next digit (7) from the dividend after 155, then repeat: 1557 / 257

Moving on to step 8:
The number 257 fits into 1557 6 times, leaving a remainder of 15.
The next digit of our result is 6. 
Result so far: 305086.0
The remainder is 15 after subtracting 1542 from 1557.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 9:
257 can be fit into 150 0 times, resulting in a remainder of 150.
Write down 0 as next digit of the result. 
Result so far: 305086.0
The remainder is 150 after subtracting 0 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 10:
The number 257 fits into 1500 5 times, leaving a remainder of 215.
Write down 5 as next digit of the result. 
Result so far: 305086.05
Deduct 1285 from 1500 and we're left with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Let's proceed to step 11:
257 goes into 2150 8 times with a remainder of 94.
Use 8 as the next digit of our solution. 
Result so far: 305086.058
Subtract 2056 from 2150 to get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Let's proceed to step 12:
940 divided by 257 is 3 with a remainder of 169.
Use 3 as the next digit of our solution. 
Result so far: 305086.0583
If we take 771 away from 940, we end up with 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Let's proceed to step 13:
257 goes into 1690 6 times with a remainder of 148.
Put 6 as the next digit of the answer. 
Result so far: 305086.05836
Subtracting 1542 from 1690 leaves us with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Going ahead to step 14:
257 goes into 1480 5 times with a remainder of 195.
The next digit of our result is 5. 
Result so far: 305086.058365
If we subtract 1285 from 1480, we get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

On to step 15:
257 goes into 1950 7 times with a remainder of 151.
Write down 7 as next digit of the result. 
Result so far: 305086.0583657
Subtract 1799 from 1950 to get 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Moving on to step 16:
257 can be fit into 1510 5 times, resulting in a remainder of 225.
Use 5 as the next digit of our solution. 
Result so far: 305086.05836575
Subtracting 1285 from 1510 leaves us with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Our division results in 305086.05836575 with a remaining 2.25e-07.
