Let's divide 21030662 by 276
We're looking to find how many times 276 goes into 21030662.

On to step 1:
If we divide 2 by 276, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 276

Step 2:
When dividing 21 by 276, we get 0 with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Fetch the next digit (0) from the dividend, attach it to 21 and continue: 210 / 276

Advancing to step 3:
276 can be fit into 210 0 times, resulting in a remainder of 210.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 210, we end up with 210.
Take the next digit (3) from the dividend and append it to 210, then repeat: 2103 / 276

Going ahead to step 4:
276 can be fit into 2103 7 times, resulting in a remainder of 171.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 1932 from 2103 and we're left with 171.
Include the next digit (0) from the dividend after 171, then repeat: 1710 / 276

Moving on to step 5:
1710 divided by 276 is 6 with a remainder of 54.
Put 6 as the next digit of the answer. 
Result so far: 76.0
Subtract 1656 from 1710 to get 54.
Include the next digit (6) from the dividend after 54, then repeat: 546 / 276

Let's proceed to step 6:
276 can be fit into 546 1 times, resulting in a remainder of 270.
Write down 1 as next digit of the result. 
Result so far: 761.0
Deduct 276 from 546 and we're left with 270.
Include the next digit (6) from the dividend after 270, then repeat: 2706 / 276

Let's proceed to step 7:
276 can be fit into 2706 9 times, resulting in a remainder of 222.
Record the quotient 9 as the next digit in the result. 
Result so far: 7619.0
The remainder is 222 after subtracting 2484 from 2706.
Append the next digit (2) from the dividend to 222 and continue with: 2222 / 276

Moving on to step 8:
276 goes into 2222 8 times with a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 76198.0
Deduct 2208 from 2222 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 9:
140 divided by 276 is 0 with a remainder of 140.
Write down 0 as next digit of the result. 
Result so far: 76198.0
If we take 0 away from 140, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 10:
If we divide 1400 by 276, we get 5 and a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 76198.05
The remainder is 20 after subtracting 1380 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 11:
When dividing 200 by 276, we get 0 with a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 76198.05
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 12:
276 can be fit into 2000 7 times, resulting in a remainder of 68.
Record the quotient 7 as the next digit in the result. 
Result so far: 76198.0507
Deduct 1932 from 2000 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 13:
680 divided by 276 is 2 with a remainder of 128.
Put 2 as the next digit of the answer. 
Result so far: 76198.05072
If we subtract 552 from 680, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Advancing to step 14:
The number 276 fits into 1280 4 times, leaving a remainder of 176.
Write down 4 as next digit of the result. 
Result so far: 76198.050724
Subtract 1104 from 1280 to get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

On to step 15:
276 can be fit into 1760 6 times, resulting in a remainder of 104.
Put 6 as the next digit of the answer. 
Result so far: 76198.0507246
Subtracting 1656 from 1760 leaves us with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

On to step 16:
The number 276 fits into 1040 3 times, leaving a remainder of 212.
Use 3 as the next digit of our solution. 
Result so far: 76198.05072463
If we take 828 away from 1040, we end up with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

The final outcome is 76198.05072463, with a leftover of 2.12e-07.
