We divide 87172505 by 277
We want to divide 87172505 by 277.

Moving on to step 1:
277 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 277

Step 2:
The number 277 fits into 87 0 times, leaving a remainder of 87.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 87 and we're left with 87.
Grab the next digit (1) from the dividend, add it to 87, then carry on: 871 / 277

Moving on to step 3:
The number 277 fits into 871 3 times, leaving a remainder of 40.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 831 from 871 and we're left with 40.
Grab the next digit (7) from the dividend, add it to 40, then carry on: 407 / 277

Going ahead to step 4:
If we divide 407 by 277, we get 1 and a remainder of 130.
The next digit of our result is 1. 
Result so far: 31.0
Subtract 277 from 407 to get 130.
Bring next digit (2) of the dividend behind the 130 and repeat the process: 1302 / 277

Going ahead to step 5:
When dividing 1302 by 277, we get 4 with a remainder of 194.
The next digit of our result is 4. 
Result so far: 314.0
Subtracting 1108 from 1302 leaves us with 194.
Include the next digit (5) from the dividend after 194, then repeat: 1945 / 277

On to step 6:
If we divide 1945 by 277, we get 7 and a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 3147.0
Subtracting 1939 from 1945 leaves us with 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 277

Step 7:
When dividing 60 by 277, we get 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 31470.0
The remainder is 60 after subtracting 0 from 60.
Fetch the next digit (5) from the dividend, attach it to 60 and continue: 605 / 277

Going ahead to step 8:
When dividing 605 by 277, we get 2 with a remainder of 51.
Use 2 as the next digit of our solution. 
Result so far: 314702.0
If we take 554 away from 605, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 9:
If we divide 510 by 277, we get 1 and a remainder of 233.
The next digit of our result is 1. 
Result so far: 314702.1
If we subtract 277 from 510, we get 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

On to step 10:
If we divide 2330 by 277, we get 8 and a remainder of 114.
Record the quotient 8 as the next digit in the result. 
Result so far: 314702.18
Deduct 2216 from 2330 and we're left with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Advancing to step 11:
1140 divided by 277 is 4 with a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 314702.184
Subtract 1108 from 1140 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.

Advancing to step 12:
320 divided by 277 is 1 with a remainder of 43.
The number 1 becomes the next digit in our result. 
Result so far: 314702.1841
If we take 277 away from 320, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 13:
277 can be fit into 430 1 times, resulting in a remainder of 153.
Write down 1 as next digit of the result. 
Result so far: 314702.18411
Deduct 277 from 430 and we're left with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

The final result is 314702.18411 with a remainder of 0.000153.
