16609690 ÷ 89 
We want to divide 16609690 by 89.

Advancing to step 1:
The number 89 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 89

Let's proceed to step 2:
89 can be fit into 16 0 times, resulting in a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 16 after subtracting 0 from 16.
Grab the next digit (6) from the dividend, add it to 16, then carry on: 166 / 89

Step 3:
89 goes into 166 1 times with a remainder of 77.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 89 from 166 to get 77.
Take the next digit (0) from the dividend and append it to 77, then repeat: 770 / 89

Let's proceed to step 4:
89 can be fit into 770 8 times, resulting in a remainder of 58.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
If we take 712 away from 770, we end up with 58.
Take the next digit (9) from the dividend and append it to 58, then repeat: 589 / 89

On to step 5:
When dividing 589 by 89, we get 6 with a remainder of 55.
Record the quotient 6 as the next digit in the result. 
Result so far: 186.0
Subtract 534 from 589 to get 55.
Append the next digit (6) from the dividend to 55 and continue with: 556 / 89

Step 6:
The number 89 fits into 556 6 times, leaving a remainder of 22.
Record the quotient 6 as the next digit in the result. 
Result so far: 1866.0
Subtracting 534 from 556 leaves us with 22.
Fetch the next digit (9) from the dividend, attach it to 22 and continue: 229 / 89

Advancing to step 7:
If we divide 229 by 89, we get 2 and a remainder of 51.
The number 2 becomes the next digit in our result. 
Result so far: 18662.0
Subtracting 178 from 229 leaves us with 51.
Fetch the next digit (0) from the dividend, attach it to 51 and continue: 510 / 89

On to step 8:
89 goes into 510 5 times with a remainder of 65.
The next digit of our result is 5. 
Result so far: 186625.0
Subtract 445 from 510 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 9:
650 divided by 89 is 7 with a remainder of 27.
The number 7 becomes the next digit in our result. 
Result so far: 186625.7
If we take 623 away from 650, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 10:
89 can be fit into 270 3 times, resulting in a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 186625.73
Deduct 267 from 270 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 11:
The number 89 fits into 30 0 times, leaving a remainder of 30.
The next digit of our result is 0. 
Result so far: 186625.73
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 12:
The number 89 fits into 300 3 times, leaving a remainder of 33.
Write down 3 as next digit of the result. 
Result so far: 186625.7303
If we subtract 267 from 300, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 13:
If we divide 330 by 89, we get 3 and a remainder of 63.
The number 3 becomes the next digit in our result. 
Result so far: 186625.73033
The remainder is 63 after subtracting 267 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

The final outcome is 186625.73033, with a leftover of 6.3e-05.
