We divide 21029191 by 663
We want to figure out the number of times 21029191 can be divided by 663.

Let's proceed to step 1:
If we divide 2 by 663, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 663

Moving on to step 2:
The number 663 fits into 21 0 times, leaving a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Take the next digit (0) from the dividend and append it to 21, then repeat: 210 / 663

Moving on to step 3:
If we divide 210 by 663, we get 0 and a remainder of 210.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 210, we end up with 210.
Grab the next digit (2) from the dividend, add it to 210, then carry on: 2102 / 663

Moving on to step 4:
663 can be fit into 2102 3 times, resulting in a remainder of 113.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 1989 away from 2102, we end up with 113.
Grab the next digit (9) from the dividend, add it to 113, then carry on: 1139 / 663

Moving on to step 5:
1139 divided by 663 is 1 with a remainder of 476.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
The remainder is 476 after subtracting 663 from 1139.
Fetch the next digit (1) from the dividend, attach it to 476 and continue: 4761 / 663

Step 6:
The number 663 fits into 4761 7 times, leaving a remainder of 120.
The next digit of our result is 7. 
Result so far: 317.0
The remainder is 120 after subtracting 4641 from 4761.
Append the next digit (9) from the dividend to 120 and continue with: 1209 / 663

Advancing to step 7:
1209 divided by 663 is 1 with a remainder of 546.
Write down 1 as next digit of the result. 
Result so far: 3171.0
The remainder is 546 after subtracting 663 from 1209.
Append the next digit (1) from the dividend to 546 and continue with: 5461 / 663

On to step 8:
5461 divided by 663 is 8 with a remainder of 157.
Record the quotient 8 as the next digit in the result. 
Result so far: 31718.0
Subtracting 5304 from 5461 leaves us with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

On to step 9:
663 goes into 1570 2 times with a remainder of 244.
Write down 2 as next digit of the result. 
Result so far: 31718.2
Subtracting 1326 from 1570 leaves us with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Advancing to step 10:
663 goes into 2440 3 times with a remainder of 451.
Record the quotient 3 as the next digit in the result. 
Result so far: 31718.23
Deduct 1989 from 2440 and we're left with 451.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4510, and continue the process.

Going ahead to step 11:
The number 663 fits into 4510 6 times, leaving a remainder of 532.
Record the quotient 6 as the next digit in the result. 
Result so far: 31718.236
Subtract 3978 from 4510 to get 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Advancing to step 12:
If we divide 5320 by 663, we get 8 and a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 31718.2368
Subtract 5304 from 5320 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 13:
The number 663 fits into 160 0 times, leaving a remainder of 160.
Write down 0 as next digit of the result. 
Result so far: 31718.2368
Subtracting 0 from 160 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 14:
1600 divided by 663 is 2 with a remainder of 274.
Write down 2 as next digit of the result. 
Result so far: 31718.236802
If we subtract 1326 from 1600, we get 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Let's proceed to step 15:
663 can be fit into 2740 4 times, resulting in a remainder of 88.
Record the quotient 4 as the next digit in the result. 
Result so far: 31718.2368024
Deduct 2652 from 2740 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 16:
When dividing 880 by 663, we get 1 with a remainder of 217.
Write down 1 as next digit of the result. 
Result so far: 31718.23680241
If we subtract 663 from 880, we get 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

After the division, we end up with 31718.23680241 and a remainder of 2.17e-07.
