We look at the division of 35123412 by 286 
Our goal is to divide 35123412 by 286.

Moving on to step 1:
286 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 286

On to step 2:
The number 286 fits into 35 0 times, leaving a remainder of 35.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 35, we get 35.
Grab the next digit (1) from the dividend, add it to 35, then carry on: 351 / 286

Step 3:
When dividing 351 by 286, we get 1 with a remainder of 65.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 286 from 351, we get 65.
Include the next digit (2) from the dividend after 65, then repeat: 652 / 286

Advancing to step 4:
When dividing 652 by 286, we get 2 with a remainder of 80.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtract 572 from 652 to get 80.
Grab the next digit (3) from the dividend, add it to 80, then carry on: 803 / 286

Advancing to step 5:
286 can be fit into 803 2 times, resulting in a remainder of 231.
The next digit of our result is 2. 
Result so far: 122.0
If we take 572 away from 803, we end up with 231.
Bring next digit (4) of the dividend behind the 231 and repeat the process: 2314 / 286

On to step 6:
When dividing 2314 by 286, we get 8 with a remainder of 26.
Use 8 as the next digit of our solution. 
Result so far: 1228.0
Deduct 2288 from 2314 and we're left with 26.
Append the next digit (1) from the dividend to 26 and continue with: 261 / 286

Advancing to step 7:
286 goes into 261 0 times with a remainder of 261.
Write down 0 as next digit of the result. 
Result so far: 12280.0
Subtract 0 from 261 to get 261.
Append the next digit (2) from the dividend to 261 and continue with: 2612 / 286

Moving on to step 8:
When dividing 2612 by 286, we get 9 with a remainder of 38.
Record the quotient 9 as the next digit in the result. 
Result so far: 122809.0
Subtract 2574 from 2612 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 9:
If we divide 380 by 286, we get 1 and a remainder of 94.
Record the quotient 1 as the next digit in the result. 
Result so far: 122809.1
Deduct 286 from 380 and we're left with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Moving on to step 10:
When dividing 940 by 286, we get 3 with a remainder of 82.
The number 3 becomes the next digit in our result. 
Result so far: 122809.13
If we take 858 away from 940, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 11:
If we divide 820 by 286, we get 2 and a remainder of 248.
The number 2 becomes the next digit in our result. 
Result so far: 122809.132
Deduct 572 from 820 and we're left with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

On to step 12:
286 goes into 2480 8 times with a remainder of 192.
Put 8 as the next digit of the answer. 
Result so far: 122809.1328
If we subtract 2288 from 2480, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Going ahead to step 13:
286 can be fit into 1920 6 times, resulting in a remainder of 204.
Use 6 as the next digit of our solution. 
Result so far: 122809.13286
If we subtract 1716 from 1920, we get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Let's proceed to step 14:
286 can be fit into 2040 7 times, resulting in a remainder of 38.
The next digit of our result is 7. 
Result so far: 122809.132867
If we subtract 2002 from 2040, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 15:
When dividing 380 by 286, we get 1 with a remainder of 94.
The next digit of our result is 1. 
Result so far: 122809.1328671
The remainder is 94 after subtracting 286 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Let's proceed to step 16:
940 divided by 286 is 3 with a remainder of 82.
Use 3 as the next digit of our solution. 
Result so far: 122809.13286713
Deduct 858 from 940 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

In conclusion, the division gives 122809.13286713 with a balance of 8.2e-08.
