We divide 35153671 by 3
We want to divide 35153671 by 3.

Advancing to step 1:
If we divide 3 by 3, we get 1 and a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 3 from 3, we get 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 3

Advancing to step 2:
If we divide 5 by 3, we get 1 and a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we subtract 3 from 5, we get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 3

Step 3:
3 goes into 21 7 times with a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 117.0
Subtract 21 from 21 to get 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 3

Going ahead to step 4:
The number 3 fits into 5 1 times, leaving a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1171.0
If we take 3 away from 5, we end up with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 3

Advancing to step 5:
3 goes into 23 7 times with a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 11717.0
The remainder is 2 after subtracting 21 from 23.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 3

On to step 6:
3 can be fit into 26 8 times, resulting in a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 117178.0
Subtracting 24 from 26 leaves us with 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 3

Let's proceed to step 7:
3 can be fit into 27 9 times, resulting in a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 1171789.0
Subtracting 27 from 27 leaves us with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 3

Moving on to step 8:
If we divide 1 by 3, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 11717890.0
If we subtract 0 from 1, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 9:
3 goes into 10 3 times with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 11717890.3
If we take 9 away from 10, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 10:
If we divide 10 by 3, we get 3 and a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 11717890.33
Subtract 9 from 10 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final outcome is 11717890.33, with a leftover of 0.001.
