10899529 ÷ 426 
We want to figure out the number of times 10899529 can be divided by 426.

Step 1:
When dividing 1 by 426, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 426

Advancing to step 2:
If we divide 10 by 426, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 10 leaves us with 10.
Fetch the next digit (8) from the dividend, attach it to 10 and continue: 108 / 426

Advancing to step 3:
108 divided by 426 is 0 with a remainder of 108.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 108 after subtracting 0 from 108.
Grab the next digit (9) from the dividend, add it to 108, then carry on: 1089 / 426

Step 4:
1089 divided by 426 is 2 with a remainder of 237.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 852 from 1089 leaves us with 237.
Fetch the next digit (9) from the dividend, attach it to 237 and continue: 2379 / 426

On to step 5:
2379 divided by 426 is 5 with a remainder of 249.
Write down 5 as next digit of the result. 
Result so far: 25.0
Subtracting 2130 from 2379 leaves us with 249.
Take the next digit (5) from the dividend and append it to 249, then repeat: 2495 / 426

Going ahead to step 6:
426 goes into 2495 5 times with a remainder of 365.
Use 5 as the next digit of our solution. 
Result so far: 255.0
Deduct 2130 from 2495 and we're left with 365.
Include the next digit (2) from the dividend after 365, then repeat: 3652 / 426

Let's proceed to step 7:
426 can be fit into 3652 8 times, resulting in a remainder of 244.
Use 8 as the next digit of our solution. 
Result so far: 2558.0
Subtract 3408 from 3652 to get 244.
Grab the next digit (9) from the dividend, add it to 244, then carry on: 2449 / 426

Moving on to step 8:
426 goes into 2449 5 times with a remainder of 319.
Put 5 as the next digit of the answer. 
Result so far: 25585.0
If we take 2130 away from 2449, we end up with 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

Let's proceed to step 9:
The number 426 fits into 3190 7 times, leaving a remainder of 208.
The next digit of our result is 7. 
Result so far: 25585.7
Subtract 2982 from 3190 to get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Moving on to step 10:
The number 426 fits into 2080 4 times, leaving a remainder of 376.
Record the quotient 4 as the next digit in the result. 
Result so far: 25585.74
The remainder is 376 after subtracting 1704 from 2080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Going ahead to step 11:
426 can be fit into 3760 8 times, resulting in a remainder of 352.
Put 8 as the next digit of the answer. 
Result so far: 25585.748
Deduct 3408 from 3760 and we're left with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Step 12:
When dividing 3520 by 426, we get 8 with a remainder of 112.
Record the quotient 8 as the next digit in the result. 
Result so far: 25585.7488
Deduct 3408 from 3520 and we're left with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Our division results in 25585.7488 with a remaining 0.00112.
