We divide 90018407 by 689
We want to divide 90018407 by 689.

Moving on to step 1:
689 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 689

Advancing to step 2:
The number 689 fits into 90 0 times, leaving a remainder of 90.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 90 to get 90.
Include the next digit (0) from the dividend after 90, then repeat: 900 / 689

On to step 3:
The number 689 fits into 900 1 times, leaving a remainder of 211.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 211 after subtracting 689 from 900.
Append the next digit (1) from the dividend to 211 and continue with: 2111 / 689

Step 4:
When dividing 2111 by 689, we get 3 with a remainder of 44.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Deduct 2067 from 2111 and we're left with 44.
Bring next digit (8) of the dividend behind the 44 and repeat the process: 448 / 689

Moving on to step 5:
689 goes into 448 0 times with a remainder of 448.
Use 0 as the next digit of our solution. 
Result so far: 130.0
Subtract 0 from 448 to get 448.
Grab the next digit (4) from the dividend, add it to 448, then carry on: 4484 / 689

Step 6:
The number 689 fits into 4484 6 times, leaving a remainder of 350.
Put 6 as the next digit of the answer. 
Result so far: 1306.0
The remainder is 350 after subtracting 4134 from 4484.
Include the next digit (0) from the dividend after 350, then repeat: 3500 / 689

Advancing to step 7:
If we divide 3500 by 689, we get 5 and a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 13065.0
Subtract 3445 from 3500 to get 55.
Take the next digit (7) from the dividend and append it to 55, then repeat: 557 / 689

Let's proceed to step 8:
When dividing 557 by 689, we get 0 with a remainder of 557.
Use 0 as the next digit of our solution. 
Result so far: 130650.0
Subtract 0 from 557 to get 557.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5570, and continue the process.

Moving on to step 9:
689 goes into 5570 8 times with a remainder of 58.
Put 8 as the next digit of the answer. 
Result so far: 130650.8
If we subtract 5512 from 5570, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 10:
580 divided by 689 is 0 with a remainder of 580.
Use 0 as the next digit of our solution. 
Result so far: 130650.8
If we take 0 away from 580, we end up with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Step 11:
689 can be fit into 5800 8 times, resulting in a remainder of 288.
Use 8 as the next digit of our solution. 
Result so far: 130650.808
Subtracting 5512 from 5800 leaves us with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Let's proceed to step 12:
If we divide 2880 by 689, we get 4 and a remainder of 124.
Put 4 as the next digit of the answer. 
Result so far: 130650.8084
If we take 2756 away from 2880, we end up with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

On to step 13:
689 can be fit into 1240 1 times, resulting in a remainder of 551.
Write down 1 as next digit of the result. 
Result so far: 130650.80841
The remainder is 551 after subtracting 689 from 1240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5510, and continue the process.

Advancing to step 14:
When dividing 5510 by 689, we get 7 with a remainder of 687.
The next digit of our result is 7. 
Result so far: 130650.808417
If we subtract 4823 from 5510, we get 687.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6870, and continue the process.

Going ahead to step 15:
689 goes into 6870 9 times with a remainder of 669.
Write down 9 as next digit of the result. 
Result so far: 130650.8084179
The remainder is 669 after subtracting 6201 from 6870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6690, and continue the process.

Advancing to step 16:
The number 689 fits into 6690 9 times, leaving a remainder of 489.
The next digit of our result is 9. 
Result so far: 130650.80841799
Subtracting 6201 from 6690 leaves us with 489.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4890, and continue the process.

Our division results in 130650.80841799 with a remaining 4.89e-07.
