We're dividing 19454790 by 991 
We're looking to find how many times 991 goes into 19454790.

Moving on to step 1:
The number 991 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 991

Advancing to step 2:
When dividing 19 by 991, we get 0 with a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 19 to get 19.
Bring next digit (4) of the dividend behind the 19 and repeat the process: 194 / 991

Advancing to step 3:
991 goes into 194 0 times with a remainder of 194.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 194 and we're left with 194.
Take the next digit (5) from the dividend and append it to 194, then repeat: 1945 / 991

Moving on to step 4:
When dividing 1945 by 991, we get 1 with a remainder of 954.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 991 from 1945 to get 954.
Fetch the next digit (4) from the dividend, attach it to 954 and continue: 9544 / 991

On to step 5:
991 goes into 9544 9 times with a remainder of 625.
Write down 9 as next digit of the result. 
Result so far: 19.0
If we subtract 8919 from 9544, we get 625.
Grab the next digit (7) from the dividend, add it to 625, then carry on: 6257 / 991

Advancing to step 6:
991 can be fit into 6257 6 times, resulting in a remainder of 311.
Record the quotient 6 as the next digit in the result. 
Result so far: 196.0
If we subtract 5946 from 6257, we get 311.
Take the next digit (9) from the dividend and append it to 311, then repeat: 3119 / 991

On to step 7:
991 can be fit into 3119 3 times, resulting in a remainder of 146.
Record the quotient 3 as the next digit in the result. 
Result so far: 1963.0
Subtract 2973 from 3119 to get 146.
Append the next digit (0) from the dividend to 146 and continue with: 1460 / 991

On to step 8:
When dividing 1460 by 991, we get 1 with a remainder of 469.
Use 1 as the next digit of our solution. 
Result so far: 19631.0
If we take 991 away from 1460, we end up with 469.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4690, and continue the process.

Let's proceed to step 9:
4690 divided by 991 is 4 with a remainder of 726.
Put 4 as the next digit of the answer. 
Result so far: 19631.4
Deduct 3964 from 4690 and we're left with 726.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7260, and continue the process.

On to step 10:
7260 divided by 991 is 7 with a remainder of 323.
Write down 7 as next digit of the result. 
Result so far: 19631.47
The remainder is 323 after subtracting 6937 from 7260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

Step 11:
991 can be fit into 3230 3 times, resulting in a remainder of 257.
The next digit of our result is 3. 
Result so far: 19631.473
Deduct 2973 from 3230 and we're left with 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

Advancing to step 12:
991 can be fit into 2570 2 times, resulting in a remainder of 588.
Use 2 as the next digit of our solution. 
Result so far: 19631.4732
The remainder is 588 after subtracting 1982 from 2570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

Moving on to step 13:
991 can be fit into 5880 5 times, resulting in a remainder of 925.
Write down 5 as next digit of the result. 
Result so far: 19631.47325
Deduct 4955 from 5880 and we're left with 925.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9250, and continue the process.

Let's proceed to step 14:
If we divide 9250 by 991, we get 9 and a remainder of 331.
The next digit of our result is 9. 
Result so far: 19631.473259
Subtract 8919 from 9250 to get 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Moving on to step 15:
991 can be fit into 3310 3 times, resulting in a remainder of 337.
The next digit of our result is 3. 
Result so far: 19631.4732593
The remainder is 337 after subtracting 2973 from 3310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

On to step 16:
991 can be fit into 3370 3 times, resulting in a remainder of 397.
Record the quotient 3 as the next digit in the result. 
Result so far: 19631.47325933
Deduct 2973 from 3370 and we're left with 397.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

The final outcome is 19631.47325933, with a leftover of 3.97e-07.
