21763443 divided by 309 
Our goal is to divide 21763443 by 309.

On to step 1:
2 divided by 309 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 309

Advancing to step 2:
When dividing 21 by 309, we get 0 with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Fetch the next digit (7) from the dividend, attach it to 21 and continue: 217 / 309

Moving on to step 3:
The number 309 fits into 217 0 times, leaving a remainder of 217.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 217 leaves us with 217.
Bring next digit (6) of the dividend behind the 217 and repeat the process: 2176 / 309

On to step 4:
When dividing 2176 by 309, we get 7 with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 2163 from 2176, we get 13.
Grab the next digit (3) from the dividend, add it to 13, then carry on: 133 / 309

On to step 5:
309 goes into 133 0 times with a remainder of 133.
Record the quotient 0 as the next digit in the result. 
Result so far: 70.0
If we subtract 0 from 133, we get 133.
Bring next digit (4) of the dividend behind the 133 and repeat the process: 1334 / 309

Let's proceed to step 6:
309 goes into 1334 4 times with a remainder of 98.
Put 4 as the next digit of the answer. 
Result so far: 704.0
Deduct 1236 from 1334 and we're left with 98.
Include the next digit (4) from the dividend after 98, then repeat: 984 / 309

Let's proceed to step 7:
309 goes into 984 3 times with a remainder of 57.
The number 3 becomes the next digit in our result. 
Result so far: 7043.0
The remainder is 57 after subtracting 927 from 984.
Include the next digit (3) from the dividend after 57, then repeat: 573 / 309

Step 8:
If we divide 573 by 309, we get 1 and a remainder of 264.
The number 1 becomes the next digit in our result. 
Result so far: 70431.0
If we subtract 309 from 573, we get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Moving on to step 9:
If we divide 2640 by 309, we get 8 and a remainder of 168.
Write down 8 as next digit of the result. 
Result so far: 70431.8
Subtracting 2472 from 2640 leaves us with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Advancing to step 10:
When dividing 1680 by 309, we get 5 with a remainder of 135.
Write down 5 as next digit of the result. 
Result so far: 70431.85
If we subtract 1545 from 1680, we get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Going ahead to step 11:
1350 divided by 309 is 4 with a remainder of 114.
Use 4 as the next digit of our solution. 
Result so far: 70431.854
Subtracting 1236 from 1350 leaves us with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Step 12:
When dividing 1140 by 309, we get 3 with a remainder of 213.
Record the quotient 3 as the next digit in the result. 
Result so far: 70431.8543
If we take 927 away from 1140, we end up with 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Let's proceed to step 13:
If we divide 2130 by 309, we get 6 and a remainder of 276.
The number 6 becomes the next digit in our result. 
Result so far: 70431.85436
If we subtract 1854 from 2130, we get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Step 14:
The number 309 fits into 2760 8 times, leaving a remainder of 288.
Record the quotient 8 as the next digit in the result. 
Result so far: 70431.854368
Subtract 2472 from 2760 to get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Moving on to step 15:
309 can be fit into 2880 9 times, resulting in a remainder of 99.
The number 9 becomes the next digit in our result. 
Result so far: 70431.8543689
Deduct 2781 from 2880 and we're left with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Advancing to step 16:
990 divided by 309 is 3 with a remainder of 63.
Use 3 as the next digit of our solution. 
Result so far: 70431.85436893
The remainder is 63 after subtracting 927 from 990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

In conclusion, the division gives 70431.85436893 with a balance of 6.3e-08.
