80646606 ÷ 429 
We want to figure out the number of times 80646606 can be divided by 429.

Going ahead to step 1:
The number 429 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 429

Let's proceed to step 2:
If we divide 80 by 429, we get 0 and a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Grab the next digit (6) from the dividend, add it to 80, then carry on: 806 / 429

On to step 3:
429 can be fit into 806 1 times, resulting in a remainder of 377.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 429 away from 806, we end up with 377.
Bring next digit (4) of the dividend behind the 377 and repeat the process: 3774 / 429

Step 4:
When dividing 3774 by 429, we get 8 with a remainder of 342.
The next digit of our result is 8. 
Result so far: 18.0
The remainder is 342 after subtracting 3432 from 3774.
Append the next digit (6) from the dividend to 342 and continue with: 3426 / 429

Advancing to step 5:
When dividing 3426 by 429, we get 7 with a remainder of 423.
The next digit of our result is 7. 
Result so far: 187.0
Subtract 3003 from 3426 to get 423.
Append the next digit (6) from the dividend to 423 and continue with: 4236 / 429

Step 6:
429 goes into 4236 9 times with a remainder of 375.
Use 9 as the next digit of our solution. 
Result so far: 1879.0
Subtracting 3861 from 4236 leaves us with 375.
Append the next digit (0) from the dividend to 375 and continue with: 3750 / 429

Let's proceed to step 7:
The number 429 fits into 3750 8 times, leaving a remainder of 318.
The next digit of our result is 8. 
Result so far: 18798.0
The remainder is 318 after subtracting 3432 from 3750.
Grab the next digit (6) from the dividend, add it to 318, then carry on: 3186 / 429

Let's proceed to step 8:
429 can be fit into 3186 7 times, resulting in a remainder of 183.
Put 7 as the next digit of the answer. 
Result so far: 187987.0
The remainder is 183 after subtracting 3003 from 3186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

On to step 9:
1830 divided by 429 is 4 with a remainder of 114.
Use 4 as the next digit of our solution. 
Result so far: 187987.4
Deduct 1716 from 1830 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 10:
1140 divided by 429 is 2 with a remainder of 282.
Use 2 as the next digit of our solution. 
Result so far: 187987.42
Deduct 858 from 1140 and we're left with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Advancing to step 11:
429 goes into 2820 6 times with a remainder of 246.
The next digit of our result is 6. 
Result so far: 187987.426
Subtracting 2574 from 2820 leaves us with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Advancing to step 12:
2460 divided by 429 is 5 with a remainder of 315.
The next digit of our result is 5. 
Result so far: 187987.4265
If we take 2145 away from 2460, we end up with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Step 13:
429 can be fit into 3150 7 times, resulting in a remainder of 147.
Put 7 as the next digit of the answer. 
Result so far: 187987.42657
The remainder is 147 after subtracting 3003 from 3150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

On to step 14:
When dividing 1470 by 429, we get 3 with a remainder of 183.
Put 3 as the next digit of the answer. 
Result so far: 187987.426573
Deduct 1287 from 1470 and we're left with 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

On to step 15:
The number 429 fits into 1830 4 times, leaving a remainder of 114.
Write down 4 as next digit of the result. 
Result so far: 187987.4265734
The remainder is 114 after subtracting 1716 from 1830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Step 16:
1140 divided by 429 is 2 with a remainder of 282.
The number 2 becomes the next digit in our result. 
Result so far: 187987.42657342
Subtracting 858 from 1140 leaves us with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Our division results in 187987.42657342 with a remaining 2.82e-07.
