Let's divide 16399989 by 920
Our goal is to divide 16399989 by 920.

Advancing to step 1:
The number 920 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 920

Going ahead to step 2:
The number 920 fits into 16 0 times, leaving a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 16 after subtracting 0 from 16.
Fetch the next digit (3) from the dividend, attach it to 16 and continue: 163 / 920

On to step 3:
920 can be fit into 163 0 times, resulting in a remainder of 163.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 163 leaves us with 163.
Fetch the next digit (9) from the dividend, attach it to 163 and continue: 1639 / 920

On to step 4:
The number 920 fits into 1639 1 times, leaving a remainder of 719.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 920 from 1639 to get 719.
Fetch the next digit (9) from the dividend, attach it to 719 and continue: 7199 / 920

Advancing to step 5:
920 can be fit into 7199 7 times, resulting in a remainder of 759.
Write down 7 as next digit of the result. 
Result so far: 17.0
Deduct 6440 from 7199 and we're left with 759.
Bring next digit (9) of the dividend behind the 759 and repeat the process: 7599 / 920

Advancing to step 6:
The number 920 fits into 7599 8 times, leaving a remainder of 239.
Use 8 as the next digit of our solution. 
Result so far: 178.0
The remainder is 239 after subtracting 7360 from 7599.
Bring next digit (8) of the dividend behind the 239 and repeat the process: 2398 / 920

Going ahead to step 7:
The number 920 fits into 2398 2 times, leaving a remainder of 558.
The next digit of our result is 2. 
Result so far: 1782.0
Subtract 1840 from 2398 to get 558.
Append the next digit (9) from the dividend to 558 and continue with: 5589 / 920

Going ahead to step 8:
920 can be fit into 5589 6 times, resulting in a remainder of 69.
Write down 6 as next digit of the result. 
Result so far: 17826.0
Subtracting 5520 from 5589 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 9:
When dividing 690 by 920, we get 0 with a remainder of 690.
Put 0 as the next digit of the answer. 
Result so far: 17826.0
The remainder is 690 after subtracting 0 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Advancing to step 10:
6900 divided by 920 is 7 with a remainder of 460.
Put 7 as the next digit of the answer. 
Result so far: 17826.07
The remainder is 460 after subtracting 6440 from 6900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Step 11:
920 can be fit into 4600 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 17826.075
If we take 4600 away from 4600, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 12:
0 divided by 920 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 17826.075
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 13:
The number 920 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 17826.075
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 17826.075, with a leftover of 0.0.
