We're dividing 21427699 by 901 
We're looking to find how many times 901 goes into 21427699.

Step 1:
If we divide 2 by 901, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 901

On to step 2:
21 divided by 901 is 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Append the next digit (4) from the dividend to 21 and continue with: 214 / 901

Step 3:
901 can be fit into 214 0 times, resulting in a remainder of 214.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 214, we get 214.
Take the next digit (2) from the dividend and append it to 214, then repeat: 2142 / 901

Moving on to step 4:
901 goes into 2142 2 times with a remainder of 340.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 1802 from 2142 leaves us with 340.
Grab the next digit (7) from the dividend, add it to 340, then carry on: 3407 / 901

On to step 5:
901 can be fit into 3407 3 times, resulting in a remainder of 704.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
If we take 2703 away from 3407, we end up with 704.
Bring next digit (6) of the dividend behind the 704 and repeat the process: 7046 / 901

Going ahead to step 6:
The number 901 fits into 7046 7 times, leaving a remainder of 739.
The next digit of our result is 7. 
Result so far: 237.0
Deduct 6307 from 7046 and we're left with 739.
Grab the next digit (9) from the dividend, add it to 739, then carry on: 7399 / 901

Going ahead to step 7:
The number 901 fits into 7399 8 times, leaving a remainder of 191.
The next digit of our result is 8. 
Result so far: 2378.0
Subtracting 7208 from 7399 leaves us with 191.
Fetch the next digit (9) from the dividend, attach it to 191 and continue: 1919 / 901

Going ahead to step 8:
1919 divided by 901 is 2 with a remainder of 117.
Write down 2 as next digit of the result. 
Result so far: 23782.0
Deduct 1802 from 1919 and we're left with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Step 9:
901 can be fit into 1170 1 times, resulting in a remainder of 269.
Use 1 as the next digit of our solution. 
Result so far: 23782.1
Subtracting 901 from 1170 leaves us with 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Moving on to step 10:
The number 901 fits into 2690 2 times, leaving a remainder of 888.
Write down 2 as next digit of the result. 
Result so far: 23782.12
Deduct 1802 from 2690 and we're left with 888.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8880, and continue the process.

On to step 11:
901 goes into 8880 9 times with a remainder of 771.
Put 9 as the next digit of the answer. 
Result so far: 23782.129
If we take 8109 away from 8880, we end up with 771.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7710, and continue the process.

Going ahead to step 12:
901 can be fit into 7710 8 times, resulting in a remainder of 502.
Put 8 as the next digit of the answer. 
Result so far: 23782.1298
Subtracting 7208 from 7710 leaves us with 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

Advancing to step 13:
If we divide 5020 by 901, we get 5 and a remainder of 515.
Use 5 as the next digit of our solution. 
Result so far: 23782.12985
Deduct 4505 from 5020 and we're left with 515.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

Moving on to step 14:
When dividing 5150 by 901, we get 5 with a remainder of 645.
Record the quotient 5 as the next digit in the result. 
Result so far: 23782.129855
If we take 4505 away from 5150, we end up with 645.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6450, and continue the process.

The final result is 23782.129855 with a remainder of 6.45e-05.
