We look at the division of 21773820 by 431 
We want to figure out the number of times 21773820 can be divided by 431.

Going ahead to step 1:
When dividing 2 by 431, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 431

Step 2:
431 can be fit into 21 0 times, resulting in a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Bring next digit (7) of the dividend behind the 21 and repeat the process: 217 / 431

Let's proceed to step 3:
217 divided by 431 is 0 with a remainder of 217.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 217 to get 217.
Bring next digit (7) of the dividend behind the 217 and repeat the process: 2177 / 431

On to step 4:
431 goes into 2177 5 times with a remainder of 22.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtracting 2155 from 2177 leaves us with 22.
Bring next digit (3) of the dividend behind the 22 and repeat the process: 223 / 431

Advancing to step 5:
The number 431 fits into 223 0 times, leaving a remainder of 223.
The next digit of our result is 0. 
Result so far: 50.0
The remainder is 223 after subtracting 0 from 223.
Grab the next digit (8) from the dividend, add it to 223, then carry on: 2238 / 431

Step 6:
The number 431 fits into 2238 5 times, leaving a remainder of 83.
Put 5 as the next digit of the answer. 
Result so far: 505.0
If we take 2155 away from 2238, we end up with 83.
Fetch the next digit (2) from the dividend, attach it to 83 and continue: 832 / 431

Let's proceed to step 7:
When dividing 832 by 431, we get 1 with a remainder of 401.
The number 1 becomes the next digit in our result. 
Result so far: 5051.0
Deduct 431 from 832 and we're left with 401.
Grab the next digit (0) from the dividend, add it to 401, then carry on: 4010 / 431

Advancing to step 8:
When dividing 4010 by 431, we get 9 with a remainder of 131.
Put 9 as the next digit of the answer. 
Result so far: 50519.0
Subtracting 3879 from 4010 leaves us with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Going ahead to step 9:
431 can be fit into 1310 3 times, resulting in a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 50519.3
If we subtract 1293 from 1310, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 10:
If we divide 170 by 431, we get 0 and a remainder of 170.
Put 0 as the next digit of the answer. 
Result so far: 50519.3
Subtracting 0 from 170 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Going ahead to step 11:
When dividing 1700 by 431, we get 3 with a remainder of 407.
Use 3 as the next digit of our solution. 
Result so far: 50519.303
If we subtract 1293 from 1700, we get 407.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

On to step 12:
4070 divided by 431 is 9 with a remainder of 191.
Write down 9 as next digit of the result. 
Result so far: 50519.3039
The remainder is 191 after subtracting 3879 from 4070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Step 13:
431 can be fit into 1910 4 times, resulting in a remainder of 186.
Use 4 as the next digit of our solution. 
Result so far: 50519.30394
Subtracting 1724 from 1910 leaves us with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Step 14:
431 goes into 1860 4 times with a remainder of 136.
Put 4 as the next digit of the answer. 
Result so far: 50519.303944
Subtracting 1724 from 1860 leaves us with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

After the division, we end up with 50519.303944 and a remainder of 1.36e-05.
