We're dividing 77866860 by 452 
Let's see how many times 452 fits into 77866860.

Going ahead to step 1:
The number 452 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 452

Going ahead to step 2:
452 can be fit into 77 0 times, resulting in a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Fetch the next digit (8) from the dividend, attach it to 77 and continue: 778 / 452

Moving on to step 3:
452 goes into 778 1 times with a remainder of 326.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 452 away from 778, we end up with 326.
Fetch the next digit (6) from the dividend, attach it to 326 and continue: 3266 / 452

Advancing to step 4:
452 can be fit into 3266 7 times, resulting in a remainder of 102.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
If we take 3164 away from 3266, we end up with 102.
Bring next digit (6) of the dividend behind the 102 and repeat the process: 1026 / 452

Step 5:
When dividing 1026 by 452, we get 2 with a remainder of 122.
The next digit of our result is 2. 
Result so far: 172.0
If we take 904 away from 1026, we end up with 122.
Fetch the next digit (8) from the dividend, attach it to 122 and continue: 1228 / 452

Let's proceed to step 6:
1228 divided by 452 is 2 with a remainder of 324.
The next digit of our result is 2. 
Result so far: 1722.0
Subtracting 904 from 1228 leaves us with 324.
Bring next digit (6) of the dividend behind the 324 and repeat the process: 3246 / 452

On to step 7:
If we divide 3246 by 452, we get 7 and a remainder of 82.
Use 7 as the next digit of our solution. 
Result so far: 17227.0
If we take 3164 away from 3246, we end up with 82.
Include the next digit (0) from the dividend after 82, then repeat: 820 / 452

On to step 8:
452 goes into 820 1 times with a remainder of 368.
The next digit of our result is 1. 
Result so far: 172271.0
Subtract 452 from 820 to get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Advancing to step 9:
3680 divided by 452 is 8 with a remainder of 64.
Record the quotient 8 as the next digit in the result. 
Result so far: 172271.8
If we subtract 3616 from 3680, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 10:
452 can be fit into 640 1 times, resulting in a remainder of 188.
The next digit of our result is 1. 
Result so far: 172271.81
The remainder is 188 after subtracting 452 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Advancing to step 11:
452 can be fit into 1880 4 times, resulting in a remainder of 72.
The next digit of our result is 4. 
Result so far: 172271.814
Subtract 1808 from 1880 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 12:
452 goes into 720 1 times with a remainder of 268.
Put 1 as the next digit of the answer. 
Result so far: 172271.8141
If we take 452 away from 720, we end up with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Let's proceed to step 13:
2680 divided by 452 is 5 with a remainder of 420.
The next digit of our result is 5. 
Result so far: 172271.81415
If we take 2260 away from 2680, we end up with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Moving on to step 14:
The number 452 fits into 4200 9 times, leaving a remainder of 132.
Record the quotient 9 as the next digit in the result. 
Result so far: 172271.814159
If we subtract 4068 from 4200, we get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Moving on to step 15:
452 goes into 1320 2 times with a remainder of 416.
The number 2 becomes the next digit in our result. 
Result so far: 172271.8141592
Subtracting 904 from 1320 leaves us with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Let's proceed to step 16:
When dividing 4160 by 452, we get 9 with a remainder of 92.
Put 9 as the next digit of the answer. 
Result so far: 172271.81415929
Subtract 4068 from 4160 to get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Our division results in 172271.81415929 with a remaining 9.2e-08.
