We're dividing 21320187 by 277 
We want to divide 21320187 by 277.

Moving on to step 1:
The number 277 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 277

On to step 2:
If we divide 21 by 277, we get 0 and a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Include the next digit (3) from the dividend after 21, then repeat: 213 / 277

Advancing to step 3:
When dividing 213 by 277, we get 0 with a remainder of 213.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 213 and we're left with 213.
Bring next digit (2) of the dividend behind the 213 and repeat the process: 2132 / 277

Advancing to step 4:
277 can be fit into 2132 7 times, resulting in a remainder of 193.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 1939 away from 2132, we end up with 193.
Grab the next digit (0) from the dividend, add it to 193, then carry on: 1930 / 277

On to step 5:
If we divide 1930 by 277, we get 6 and a remainder of 268.
Write down 6 as next digit of the result. 
Result so far: 76.0
If we subtract 1662 from 1930, we get 268.
Bring next digit (1) of the dividend behind the 268 and repeat the process: 2681 / 277

Step 6:
277 can be fit into 2681 9 times, resulting in a remainder of 188.
Record the quotient 9 as the next digit in the result. 
Result so far: 769.0
Subtracting 2493 from 2681 leaves us with 188.
Fetch the next digit (8) from the dividend, attach it to 188 and continue: 1888 / 277

Going ahead to step 7:
The number 277 fits into 1888 6 times, leaving a remainder of 226.
Record the quotient 6 as the next digit in the result. 
Result so far: 7696.0
Subtract 1662 from 1888 to get 226.
Take the next digit (7) from the dividend and append it to 226, then repeat: 2267 / 277

Step 8:
When dividing 2267 by 277, we get 8 with a remainder of 51.
Put 8 as the next digit of the answer. 
Result so far: 76968.0
If we subtract 2216 from 2267, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 9:
If we divide 510 by 277, we get 1 and a remainder of 233.
Use 1 as the next digit of our solution. 
Result so far: 76968.1
If we subtract 277 from 510, we get 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Moving on to step 10:
The number 277 fits into 2330 8 times, leaving a remainder of 114.
Use 8 as the next digit of our solution. 
Result so far: 76968.18
Subtract 2216 from 2330 to get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Advancing to step 11:
277 goes into 1140 4 times with a remainder of 32.
The next digit of our result is 4. 
Result so far: 76968.184
Subtracting 1108 from 1140 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 12:
When dividing 320 by 277, we get 1 with a remainder of 43.
Use 1 as the next digit of our solution. 
Result so far: 76968.1841
Deduct 277 from 320 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 13:
If we divide 430 by 277, we get 1 and a remainder of 153.
Record the quotient 1 as the next digit in the result. 
Result so far: 76968.18411
The remainder is 153 after subtracting 277 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

The final result is 76968.18411 with a remainder of 0.000153.
