97721774 ÷ 431 
We want to figure out the number of times 97721774 can be divided by 431.

On to step 1:
The number 431 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 431

On to step 2:
If we divide 97 by 431, we get 0 and a remainder of 97.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 97 and we're left with 97.
Bring next digit (7) of the dividend behind the 97 and repeat the process: 977 / 431

Let's proceed to step 3:
977 divided by 431 is 2 with a remainder of 115.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 862 from 977 and we're left with 115.
Bring next digit (2) of the dividend behind the 115 and repeat the process: 1152 / 431

Going ahead to step 4:
When dividing 1152 by 431, we get 2 with a remainder of 290.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
If we subtract 862 from 1152, we get 290.
Bring next digit (1) of the dividend behind the 290 and repeat the process: 2901 / 431

Let's proceed to step 5:
2901 divided by 431 is 6 with a remainder of 315.
The number 6 becomes the next digit in our result. 
Result so far: 226.0
If we take 2586 away from 2901, we end up with 315.
Grab the next digit (7) from the dividend, add it to 315, then carry on: 3157 / 431

Going ahead to step 6:
If we divide 3157 by 431, we get 7 and a remainder of 140.
The next digit of our result is 7. 
Result so far: 2267.0
If we take 3017 away from 3157, we end up with 140.
Include the next digit (7) from the dividend after 140, then repeat: 1407 / 431

Going ahead to step 7:
431 can be fit into 1407 3 times, resulting in a remainder of 114.
The number 3 becomes the next digit in our result. 
Result so far: 22673.0
The remainder is 114 after subtracting 1293 from 1407.
Take the next digit (4) from the dividend and append it to 114, then repeat: 1144 / 431

Advancing to step 8:
431 can be fit into 1144 2 times, resulting in a remainder of 282.
Use 2 as the next digit of our solution. 
Result so far: 226732.0
If we subtract 862 from 1144, we get 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Advancing to step 9:
2820 divided by 431 is 6 with a remainder of 234.
Use 6 as the next digit of our solution. 
Result so far: 226732.6
Subtracting 2586 from 2820 leaves us with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

On to step 10:
431 can be fit into 2340 5 times, resulting in a remainder of 185.
The next digit of our result is 5. 
Result so far: 226732.65
The remainder is 185 after subtracting 2155 from 2340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

On to step 11:
If we divide 1850 by 431, we get 4 and a remainder of 126.
Write down 4 as next digit of the result. 
Result so far: 226732.654
Subtracting 1724 from 1850 leaves us with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Step 12:
When dividing 1260 by 431, we get 2 with a remainder of 398.
Use 2 as the next digit of our solution. 
Result so far: 226732.6542
If we take 862 away from 1260, we end up with 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Step 13:
When dividing 3980 by 431, we get 9 with a remainder of 101.
Record the quotient 9 as the next digit in the result. 
Result so far: 226732.65429
Deduct 3879 from 3980 and we're left with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

On to step 14:
When dividing 1010 by 431, we get 2 with a remainder of 148.
Use 2 as the next digit of our solution. 
Result so far: 226732.654292
Subtracting 862 from 1010 leaves us with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Step 15:
431 can be fit into 1480 3 times, resulting in a remainder of 187.
The number 3 becomes the next digit in our result. 
Result so far: 226732.6542923
If we subtract 1293 from 1480, we get 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Step 16:
431 can be fit into 1870 4 times, resulting in a remainder of 146.
Put 4 as the next digit of the answer. 
Result so far: 226732.65429234
Subtract 1724 from 1870 to get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

The final outcome is 226732.65429234, with a leftover of 1.46e-07.
