Let's divide 12742470 by 351
Let's see how many times 351 fits into 12742470.

Going ahead to step 1:
When dividing 1 by 351, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 351

Moving on to step 2:
If we divide 12 by 351, we get 0 and 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.
Take the next digit (7) from the dividend and append it to 12, then repeat: 127 / 351

On to step 3:
351 can be fit into 127 0 times, resulting in a remainder of 127.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 127, we end up with 127.
Grab the next digit (4) from the dividend, add it to 127, then carry on: 1274 / 351

Moving on to step 4:
If we divide 1274 by 351, we get 3 and a remainder of 221.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 1053 from 1274, we get 221.
Take the next digit (2) from the dividend and append it to 221, then repeat: 2212 / 351

Step 5:
351 can be fit into 2212 6 times, resulting in a remainder of 106.
The next digit of our result is 6. 
Result so far: 36.0
If we subtract 2106 from 2212, we get 106.
Append the next digit (4) from the dividend to 106 and continue with: 1064 / 351

Step 6:
When dividing 1064 by 351, we get 3 with a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 363.0
Subtract 1053 from 1064 to get 11.
Bring next digit (7) of the dividend behind the 11 and repeat the process: 117 / 351

Going ahead to step 7:
The number 351 fits into 117 0 times, leaving a remainder of 117.
The number 0 becomes the next digit in our result. 
Result so far: 3630.0
If we subtract 0 from 117, we get 117.
Take the next digit (0) from the dividend and append it to 117, then repeat: 1170 / 351

Moving on to step 8:
When dividing 1170 by 351, we get 3 with a remainder of 117.
Put 3 as the next digit of the answer. 
Result so far: 36303.0
If we subtract 1053 from 1170, we get 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Let's proceed to step 9:
351 can be fit into 1170 3 times, resulting in a remainder of 117.
The next digit of our result is 3. 
Result so far: 36303.3
The remainder is 117 after subtracting 1053 from 1170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

On to step 10:
351 goes into 1170 3 times with a remainder of 117.
The number 3 becomes the next digit in our result. 
Result so far: 36303.33
If we take 1053 away from 1170, we end up with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

The final outcome is 36303.33, with a leftover of 0.117.
