77172709 ÷ 452 
We want to divide 77172709 by 452.

Moving on to step 1:
452 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 452

Going ahead to step 2:
If we divide 77 by 452, we get 0 and a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Bring next digit (1) of the dividend behind the 77 and repeat the process: 771 / 452

Going ahead to step 3:
If we divide 771 by 452, we get 1 and a remainder of 319.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 452 from 771, we get 319.
Append the next digit (7) from the dividend to 319 and continue with: 3197 / 452

Step 4:
452 goes into 3197 7 times with a remainder of 33.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Deduct 3164 from 3197 and we're left with 33.
Fetch the next digit (2) from the dividend, attach it to 33 and continue: 332 / 452

On to step 5:
When dividing 332 by 452, we get 0 with a remainder of 332.
Record the quotient 0 as the next digit in the result. 
Result so far: 170.0
If we take 0 away from 332, we end up with 332.
Take the next digit (7) from the dividend and append it to 332, then repeat: 3327 / 452

Step 6:
When dividing 3327 by 452, we get 7 with a remainder of 163.
Write down 7 as next digit of the result. 
Result so far: 1707.0
Subtract 3164 from 3327 to get 163.
Fetch the next digit (0) from the dividend, attach it to 163 and continue: 1630 / 452

Step 7:
1630 divided by 452 is 3 with a remainder of 274.
The number 3 becomes the next digit in our result. 
Result so far: 17073.0
The remainder is 274 after subtracting 1356 from 1630.
Append the next digit (9) from the dividend to 274 and continue with: 2749 / 452

On to step 8:
If we divide 2749 by 452, we get 6 and a remainder of 37.
The number 6 becomes the next digit in our result. 
Result so far: 170736.0
If we subtract 2712 from 2749, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 9:
When dividing 370 by 452, we get 0 with a remainder of 370.
Put 0 as the next digit of the answer. 
Result so far: 170736.0
The remainder is 370 after subtracting 0 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Step 10:
If we divide 3700 by 452, we get 8 and a remainder of 84.
Write down 8 as next digit of the result. 
Result so far: 170736.08
Deduct 3616 from 3700 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 11:
If we divide 840 by 452, we get 1 and a remainder of 388.
The next digit of our result is 1. 
Result so far: 170736.081
Subtract 452 from 840 to get 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Step 12:
When dividing 3880 by 452, we get 8 with a remainder of 264.
Write down 8 as next digit of the result. 
Result so far: 170736.0818
Subtract 3616 from 3880 to get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

On to step 13:
452 goes into 2640 5 times with a remainder of 380.
Record the quotient 5 as the next digit in the result. 
Result so far: 170736.08185
If we subtract 2260 from 2640, we get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

On to step 14:
The number 452 fits into 3800 8 times, leaving a remainder of 184.
The number 8 becomes the next digit in our result. 
Result so far: 170736.081858
Subtracting 3616 from 3800 leaves us with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Let's proceed to step 15:
452 goes into 1840 4 times with a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 170736.0818584
If we subtract 1808 from 1840, we 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 16:
452 goes into 320 0 times with a remainder of 320.
Put 0 as the next digit of the answer. 
Result so far: 170736.0818584
If we subtract 0 from 320, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Our division results in 170736.0818584 with a remaining 3.2e-07.
