87188779 divided by 257 
We want to figure out the number of times 87188779 can be divided by 257.

Advancing to step 1:
The number 257 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 257

On to step 2:
257 goes into 87 0 times with a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 87 leaves us with 87.
Fetch the next digit (1) from the dividend, attach it to 87 and continue: 871 / 257

On to step 3:
871 divided by 257 is 3 with a remainder of 100.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 771 away from 871, we end up with 100.
Grab the next digit (8) from the dividend, add it to 100, then carry on: 1008 / 257

Moving on to step 4:
When dividing 1008 by 257, we get 3 with a remainder of 237.
Write down 3 as next digit of the result. 
Result so far: 33.0
Subtract 771 from 1008 to get 237.
Take the next digit (8) from the dividend and append it to 237, then repeat: 2378 / 257

Moving on to step 5:
If we divide 2378 by 257, we get 9 and a remainder of 65.
The next digit of our result is 9. 
Result so far: 339.0
Subtract 2313 from 2378 to get 65.
Append the next digit (7) from the dividend to 65 and continue with: 657 / 257

Let's proceed to step 6:
The number 257 fits into 657 2 times, leaving a remainder of 143.
Write down 2 as next digit of the result. 
Result so far: 3392.0
If we subtract 514 from 657, we get 143.
Fetch the next digit (7) from the dividend, attach it to 143 and continue: 1437 / 257

On to step 7:
1437 divided by 257 is 5 with a remainder of 152.
Use 5 as the next digit of our solution. 
Result so far: 33925.0
If we take 1285 away from 1437, we end up with 152.
Take the next digit (9) from the dividend and append it to 152, then repeat: 1529 / 257

Let's proceed to step 8:
257 goes into 1529 5 times with a remainder of 244.
The next digit of our result is 5. 
Result so far: 339255.0
Deduct 1285 from 1529 and we're left with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Advancing to step 9:
257 goes into 2440 9 times with a remainder of 127.
Write down 9 as next digit of the result. 
Result so far: 339255.9
Subtract 2313 from 2440 to get 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Advancing to step 10:
1270 divided by 257 is 4 with a remainder of 242.
Write down 4 as next digit of the result. 
Result so far: 339255.94
Subtract 1028 from 1270 to get 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Step 11:
If we divide 2420 by 257, we get 9 and a remainder of 107.
The number 9 becomes the next digit in our result. 
Result so far: 339255.949
If we take 2313 away from 2420, we end up with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Moving on to step 12:
If we divide 1070 by 257, we get 4 and a remainder of 42.
Write down 4 as next digit of the result. 
Result so far: 339255.9494
Subtract 1028 from 1070 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 13:
The number 257 fits into 420 1 times, leaving a remainder of 163.
The next digit of our result is 1. 
Result so far: 339255.94941
The remainder is 163 after subtracting 257 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Advancing to step 14:
257 can be fit into 1630 6 times, resulting in a remainder of 88.
The number 6 becomes the next digit in our result. 
Result so far: 339255.949416
Subtract 1542 from 1630 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 15:
880 divided by 257 is 3 with a remainder of 109.
Use 3 as the next digit of our solution. 
Result so far: 339255.9494163
Subtract 771 from 880 to get 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

On to step 16:
257 can be fit into 1090 4 times, resulting in a remainder of 62.
Write down 4 as next digit of the result. 
Result so far: 339255.94941634
Deduct 1028 from 1090 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

The quotient of the division is 339255.94941634, and the remainder is 6.2e-08.
