Let's divide 21029878 by 83
We want to figure out the number of times 21029878 can be divided by 83.

Step 1:
83 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 83

Moving on to step 2:
83 goes into 21 0 times with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Bring next digit (0) of the dividend behind the 21 and repeat the process: 210 / 83

Advancing to step 3:
83 can be fit into 210 2 times, resulting in a remainder of 44.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 166 from 210 to get 44.
Grab the next digit (2) from the dividend, add it to 44, then carry on: 442 / 83

Step 4:
When dividing 442 by 83, we get 5 with a remainder of 27.
Use 5 as the next digit of our solution. 
Result so far: 25.0
Subtract 415 from 442 to get 27.
Bring next digit (9) of the dividend behind the 27 and repeat the process: 279 / 83

On to step 5:
279 divided by 83 is 3 with a remainder of 30.
Record the quotient 3 as the next digit in the result. 
Result so far: 253.0
Deduct 249 from 279 and we're left with 30.
Take the next digit (8) from the dividend and append it to 30, then repeat: 308 / 83

Advancing to step 6:
When dividing 308 by 83, we get 3 with a remainder of 59.
Put 3 as the next digit of the answer. 
Result so far: 2533.0
The remainder is 59 after subtracting 249 from 308.
Append the next digit (7) from the dividend to 59 and continue with: 597 / 83

Going ahead to step 7:
If we divide 597 by 83, we get 7 and a remainder of 16.
Write down 7 as next digit of the result. 
Result so far: 25337.0
If we subtract 581 from 597, we get 16.
Grab the next digit (8) from the dividend, add it to 16, then carry on: 168 / 83

On to step 8:
83 goes into 168 2 times with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 253372.0
Deduct 166 from 168 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.

Step 9:
83 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 253372.0
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 10:
The number 83 fits into 200 2 times, leaving a remainder of 34.
Use 2 as the next digit of our solution. 
Result so far: 253372.02
The remainder is 34 after subtracting 166 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 11:
83 can be fit into 340 4 times, resulting in a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 253372.024
If we subtract 332 from 340, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 12:
83 can be fit into 80 0 times, resulting in a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 253372.024
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 13:
83 can be fit into 800 9 times, resulting in a remainder of 53.
The number 9 becomes the next digit in our result. 
Result so far: 253372.02409
Deduct 747 from 800 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 14:
The number 83 fits into 530 6 times, leaving a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 253372.024096
Deduct 498 from 530 and we're left 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.

Advancing to step 15:
83 can be fit into 320 3 times, resulting in a remainder of 71.
Record the quotient 3 as the next digit in the result. 
Result so far: 253372.0240963
If we take 249 away from 320, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 16:
83 goes into 710 8 times with a remainder of 46.
Record the quotient 8 as the next digit in the result. 
Result so far: 253372.02409638
If we take 664 away from 710, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The quotient of the division is 253372.02409638, and the remainder is 4.6e-08.
