Let's divide 19645391 by 331
We want to figure out the number of times 19645391 can be divided by 331.

Let's proceed to step 1:
331 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 331

On to step 2:
When dividing 19 by 331, we get 0 with a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Bring next digit (6) of the dividend behind the 19 and repeat the process: 196 / 331

On to step 3:
331 can be fit into 196 0 times, resulting in a remainder of 196.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 196, we get 196.
Bring next digit (4) of the dividend behind the 196 and repeat the process: 1964 / 331

Going ahead to step 4:
331 goes into 1964 5 times with a remainder of 309.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 1655 from 1964 and we're left with 309.
Take the next digit (5) from the dividend and append it to 309, then repeat: 3095 / 331

Going ahead to step 5:
If we divide 3095 by 331, we get 9 and a remainder of 116.
The next digit of our result is 9. 
Result so far: 59.0
Deduct 2979 from 3095 and we're left with 116.
Fetch the next digit (3) from the dividend, attach it to 116 and continue: 1163 / 331

Step 6:
331 goes into 1163 3 times with a remainder of 170.
The next digit of our result is 3. 
Result so far: 593.0
Deduct 993 from 1163 and we're left with 170.
Bring next digit (9) of the dividend behind the 170 and repeat the process: 1709 / 331

Step 7:
1709 divided by 331 is 5 with a remainder of 54.
Record the quotient 5 as the next digit in the result. 
Result so far: 5935.0
If we take 1655 away from 1709, we end up with 54.
Take the next digit (1) from the dividend and append it to 54, then repeat: 541 / 331

Moving on to step 8:
331 can be fit into 541 1 times, resulting in a remainder of 210.
Put 1 as the next digit of the answer. 
Result so far: 59351.0
Deduct 331 from 541 and we're left with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Going ahead to step 9:
The number 331 fits into 2100 6 times, leaving a remainder of 114.
Write down 6 as next digit of the result. 
Result so far: 59351.6
The remainder is 114 after subtracting 1986 from 2100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Moving on to step 10:
1140 divided by 331 is 3 with a remainder of 147.
The next digit of our result is 3. 
Result so far: 59351.63
Subtracting 993 from 1140 leaves us with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Advancing to step 11:
1470 divided by 331 is 4 with a remainder of 146.
The number 4 becomes the next digit in our result. 
Result so far: 59351.634
Deduct 1324 from 1470 and we're left with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Let's proceed to step 12:
The number 331 fits into 1460 4 times, leaving a remainder of 136.
Write down 4 as next digit of the result. 
Result so far: 59351.6344
If we take 1324 away from 1460, we end up 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.

The quotient of the division is 59351.6344, and the remainder is 0.00136.
