We're dividing 34020671 by 426 
We want to divide 34020671 by 426.

Step 1:
3 divided by 426 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 426

On to step 2:
426 goes into 34 0 times with a remainder of 34.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 34, we get 34.
Grab the next digit (0) from the dividend, add it to 34, then carry on: 340 / 426

Going ahead to step 3:
The number 426 fits into 340 0 times, leaving a remainder of 340.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 340, we get 340.
Take the next digit (2) from the dividend and append it to 340, then repeat: 3402 / 426

Step 4:
426 goes into 3402 7 times with a remainder of 420.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 2982 from 3402 leaves us with 420.
Take the next digit (0) from the dividend and append it to 420, then repeat: 4200 / 426

Step 5:
If we divide 4200 by 426, we get 9 and a remainder of 366.
Record the quotient 9 as the next digit in the result. 
Result so far: 79.0
If we subtract 3834 from 4200, we get 366.
Fetch the next digit (6) from the dividend, attach it to 366 and continue: 3666 / 426

Moving on to step 6:
The number 426 fits into 3666 8 times, leaving a remainder of 258.
The next digit of our result is 8. 
Result so far: 798.0
Deduct 3408 from 3666 and we're left with 258.
Bring next digit (7) of the dividend behind the 258 and repeat the process: 2587 / 426

Going ahead to step 7:
426 can be fit into 2587 6 times, resulting in a remainder of 31.
Record the quotient 6 as the next digit in the result. 
Result so far: 7986.0
The remainder is 31 after subtracting 2556 from 2587.
Bring next digit (1) of the dividend behind the 31 and repeat the process: 311 / 426

Let's proceed to step 8:
The number 426 fits into 311 0 times, leaving a remainder of 311.
Use 0 as the next digit of our solution. 
Result so far: 79860.0
Deduct 0 from 311 and we're left with 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Step 9:
426 goes into 3110 7 times with a remainder of 128.
Put 7 as the next digit of the answer. 
Result so far: 79860.7
Deduct 2982 from 3110 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Let's proceed to step 10:
1280 divided by 426 is 3 with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 79860.73
The remainder is 2 after subtracting 1278 from 1280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 11:
If we divide 20 by 426, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 79860.73
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 12:
426 can be fit into 200 0 times, resulting in a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 79860.73
If we take 0 away from 200, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The quotient of the division is 79860.73, and the remainder is 0.002.
