12640537 divided by 429 
We want to figure out the number of times 12640537 can be divided by 429.

Advancing to step 1:
429 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 429

Step 2:
12 divided by 429 is 0 with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Include the next digit (6) from the dividend after 12, then repeat: 126 / 429

Let's proceed to step 3:
The number 429 fits into 126 0 times, leaving a remainder of 126.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 126 and we're left with 126.
Take the next digit (4) from the dividend and append it to 126, then repeat: 1264 / 429

Step 4:
When dividing 1264 by 429, we get 2 with a remainder of 406.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 858 from 1264, we get 406.
Append the next digit (0) from the dividend to 406 and continue with: 4060 / 429

On to step 5:
If we divide 4060 by 429, we get 9 and a remainder of 199.
The next digit of our result is 9. 
Result so far: 29.0
If we take 3861 away from 4060, we end up with 199.
Append the next digit (5) from the dividend to 199 and continue with: 1995 / 429

Moving on to step 6:
429 can be fit into 1995 4 times, resulting in a remainder of 279.
Put 4 as the next digit of the answer. 
Result so far: 294.0
Subtract 1716 from 1995 to get 279.
Fetch the next digit (3) from the dividend, attach it to 279 and continue: 2793 / 429

Step 7:
The number 429 fits into 2793 6 times, leaving a remainder of 219.
Record the quotient 6 as the next digit in the result. 
Result so far: 2946.0
Deduct 2574 from 2793 and we're left with 219.
Bring next digit (7) of the dividend behind the 219 and repeat the process: 2197 / 429

Moving on to step 8:
429 can be fit into 2197 5 times, resulting in a remainder of 52.
Record the quotient 5 as the next digit in the result. 
Result so far: 29465.0
If we take 2145 away from 2197, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 9:
520 divided by 429 is 1 with a remainder of 91.
The next digit of our result is 1. 
Result so far: 29465.1
Deduct 429 from 520 and we're left with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Advancing to step 10:
The number 429 fits into 910 2 times, leaving a remainder of 52.
The next digit of our result is 2. 
Result so far: 29465.12
Subtracting 858 from 910 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 11:
520 divided by 429 is 1 with a remainder of 91.
Use 1 as the next digit of our solution. 
Result so far: 29465.121
Subtract 429 from 520 to get 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Going ahead to step 12:
429 can be fit into 910 2 times, resulting in a remainder of 52.
Use 2 as the next digit of our solution. 
Result so far: 29465.1212
Subtracting 858 from 910 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 13:
520 divided by 429 is 1 with a remainder of 91.
Use 1 as the next digit of our solution. 
Result so far: 29465.12121
If we take 429 away from 520, we end up with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Step 14:
429 can be fit into 910 2 times, resulting in a remainder of 52.
The number 2 becomes the next digit in our result. 
Result so far: 29465.121212
If we subtract 858 from 910, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 15:
When dividing 520 by 429, we get 1 with a remainder of 91.
Write down 1 as next digit of the result. 
Result so far: 29465.1212121
The remainder is 91 after subtracting 429 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Going ahead to step 16:
910 divided by 429 is 2 with a remainder of 52.
The next digit of our result is 2. 
Result so far: 29465.12121212
If we subtract 858 from 910, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The quotient of the division is 29465.12121212, and the remainder is 5.2e-08.
