We divide 85365269 by 21
Let's see how many times 21 fits into 85365269.

Advancing to step 1:
When dividing 8 by 21, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 21

Going ahead to step 2:
When dividing 85 by 21, we get 4 with a remainder of 1.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 1 after subtracting 84 from 85.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 21

Advancing to step 3:
21 goes into 13 0 times with a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 40.0
Subtract 0 from 13 to get 13.
Fetch the next digit (6) from the dividend, attach it to 13 and continue: 136 / 21

On to step 4:
21 goes into 136 6 times with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 406.0
If we subtract 126 from 136, we get 10.
Bring next digit (5) of the dividend behind the 10 and repeat the process: 105 / 21

On to step 5:
21 can be fit into 105 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 4065.0
Subtracting 105 from 105 leaves us with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 21

Going ahead to step 6:
21 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 40650.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 21

Advancing to step 7:
If we divide 26 by 21, we get 1 and a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 406501.0
Subtract 21 from 26 to get 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 21

Advancing to step 8:
21 goes into 59 2 times with a remainder of 17.
Write down 2 as next digit of the result. 
Result so far: 4065012.0
Deduct 42 from 59 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 9:
21 goes into 170 8 times with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 4065012.8
Deduct 168 from 170 and we're left with 2.
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 10:
21 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 4065012.8
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 11:
If we divide 200 by 21, we get 9 and a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 4065012.809
Deduct 189 from 200 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 12:
21 can be fit into 110 5 times, resulting in a remainder of 5.
The next digit of our result is 5. 
Result so far: 4065012.8095
The remainder is 5 after subtracting 105 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 13:
50 divided by 21 is 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 4065012.80952
The remainder is 8 after subtracting 42 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 14:
If we divide 80 by 21, we get 3 and a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 4065012.809523
If we take 63 away from 80, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 15:
If we divide 170 by 21, we get 8 and a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 4065012.8095238
If we take 168 away from 170, we end up with 2.
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 16:
21 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 4065012.8095238
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.

The final result is 4065012.8095238 with a remainder of 2e-08.
