26917450 ÷ 426 
Our goal is to divide 26917450 by 426.

Step 1:
The number 426 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 426

On to step 2:
When dividing 26 by 426, we get 0 with a remainder of 26.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 26 and we're left with 26.
Grab the next digit (9) from the dividend, add it to 26, then carry on: 269 / 426

Advancing to step 3:
426 goes into 269 0 times with a remainder of 269.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 269, we end up with 269.
Append the next digit (1) from the dividend to 269 and continue with: 2691 / 426

Moving on to step 4:
When dividing 2691 by 426, we get 6 with a remainder of 135.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 2556 from 2691 to get 135.
Bring next digit (7) of the dividend behind the 135 and repeat the process: 1357 / 426

Step 5:
426 goes into 1357 3 times with a remainder of 79.
The number 3 becomes the next digit in our result. 
Result so far: 63.0
Subtract 1278 from 1357 to get 79.
Bring next digit (4) of the dividend behind the 79 and repeat the process: 794 / 426

Going ahead to step 6:
426 can be fit into 794 1 times, resulting in a remainder of 368.
The number 1 becomes the next digit in our result. 
Result so far: 631.0
The remainder is 368 after subtracting 426 from 794.
Append the next digit (5) from the dividend to 368 and continue with: 3685 / 426

Step 7:
When dividing 3685 by 426, we get 8 with a remainder of 277.
Record the quotient 8 as the next digit in the result. 
Result so far: 6318.0
If we take 3408 away from 3685, we end up with 277.
Take the next digit (0) from the dividend and append it to 277, then repeat: 2770 / 426

On to step 8:
If we divide 2770 by 426, we get 6 and a remainder of 214.
Put 6 as the next digit of the answer. 
Result so far: 63186.0
If we subtract 2556 from 2770, we get 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

On to step 9:
426 goes into 2140 5 times with a remainder of 10.
The next digit of our result is 5. 
Result so far: 63186.5
Subtracting 2130 from 2140 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
When dividing 100 by 426, we get 0 with a remainder of 100.
The next digit of our result is 0. 
Result so far: 63186.5
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 11:
426 goes into 1000 2 times with a remainder of 148.
Record the quotient 2 as the next digit in the result. 
Result so far: 63186.502
Subtract 852 from 1000 to get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Let's proceed to step 12:
The number 426 fits into 1480 3 times, leaving a remainder of 202.
Write down 3 as next digit of the result. 
Result so far: 63186.5023
The remainder is 202 after subtracting 1278 from 1480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Let's proceed to step 13:
426 can be fit into 2020 4 times, resulting in a remainder of 316.
Use 4 as the next digit of our solution. 
Result so far: 63186.50234
Subtracting 1704 from 2020 leaves us with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Let's proceed to step 14:
426 can be fit into 3160 7 times, resulting in a remainder of 178.
Put 7 as the next digit of the answer. 
Result so far: 63186.502347
The remainder is 178 after subtracting 2982 from 3160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Moving on to step 15:
The number 426 fits into 1780 4 times, leaving a remainder of 76.
The next digit of our result is 4. 
Result so far: 63186.5023474
Subtracting 1704 from 1780 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 16:
The number 426 fits into 760 1 times, leaving a remainder of 334.
Write down 1 as next digit of the result. 
Result so far: 63186.50234741
Deduct 426 from 760 and we're left with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

The final outcome is 63186.50234741, with a leftover of 3.34e-07.
