We look at the division of 12906170 by 429 
We want to divide 12906170 by 429.

Moving on to step 1:
429 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 429

Going ahead to step 2:
When dividing 12 by 429, we get 0 with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Include the next digit (9) from the dividend after 12, then repeat: 129 / 429

Step 3:
129 divided by 429 is 0 with a remainder of 129.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 129 and we're left with 129.
Include the next digit (0) from the dividend after 129, then repeat: 1290 / 429

Moving on to step 4:
429 can be fit into 1290 3 times, resulting in a remainder of 3.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 1287 from 1290 to get 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 429

Let's proceed to step 5:
If we divide 36 by 429, we get 0 and a remainder of 36.
Put 0 as the next digit of the answer. 
Result so far: 30.0
Subtracting 0 from 36 leaves us with 36.
Grab the next digit (1) from the dividend, add it to 36, then carry on: 361 / 429

Moving on to step 6:
When dividing 361 by 429, we get 0 with a remainder of 361.
Put 0 as the next digit of the answer. 
Result so far: 300.0
If we take 0 away from 361, we end up with 361.
Bring next digit (7) of the dividend behind the 361 and repeat the process: 3617 / 429

Step 7:
The number 429 fits into 3617 8 times, leaving a remainder of 185.
Record the quotient 8 as the next digit in the result. 
Result so far: 3008.0
The remainder is 185 after subtracting 3432 from 3617.
Include the next digit (0) from the dividend after 185, then repeat: 1850 / 429

Let's proceed to step 8:
If we divide 1850 by 429, we get 4 and a remainder of 134.
The next digit of our result is 4. 
Result so far: 30084.0
If we subtract 1716 from 1850, we get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

On to step 9:
The number 429 fits into 1340 3 times, leaving a remainder of 53.
Use 3 as the next digit of our solution. 
Result so far: 30084.3
If we take 1287 away from 1340, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 10:
If we divide 530 by 429, we get 1 and a remainder of 101.
Put 1 as the next digit of the answer. 
Result so far: 30084.31
If we subtract 429 from 530, we get 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Advancing to step 11:
429 goes into 1010 2 times with a remainder of 152.
Use 2 as the next digit of our solution. 
Result so far: 30084.312
The remainder is 152 after subtracting 858 from 1010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Advancing to step 12:
429 can be fit into 1520 3 times, resulting in a remainder of 233.
Write down 3 as next digit of the result. 
Result so far: 30084.3123
If we take 1287 away from 1520, we end up with 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Step 13:
The number 429 fits into 2330 5 times, leaving a remainder of 185.
The number 5 becomes the next digit in our result. 
Result so far: 30084.31235
The remainder is 185 after subtracting 2145 from 2330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

On to step 14:
When dividing 1850 by 429, we get 4 with a remainder of 134.
Write down 4 as next digit of the result. 
Result so far: 30084.312354
Subtracting 1716 from 1850 leaves us with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

On to step 15:
429 can be fit into 1340 3 times, resulting in a remainder of 53.
Write down 3 as next digit of the result. 
Result so far: 30084.3123543
The remainder is 53 after subtracting 1287 from 1340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 16:
530 divided by 429 is 1 with a remainder of 101.
Use 1 as the next digit of our solution. 
Result so far: 30084.31235431
Deduct 429 from 530 and we're left with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

The quotient of the division is 30084.31235431, and the remainder is 1.01e-07.
