73987465 ÷ 990 
Our goal is to divide 73987465 by 990.

Let's proceed to step 1:
990 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 990

Let's proceed to step 2:
If we divide 73 by 990, we get 0 and a remainder of 73.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 73 and we're left with 73.
Bring next digit (9) of the dividend behind the 73 and repeat the process: 739 / 990

Advancing to step 3:
When dividing 739 by 990, we get 0 with a remainder of 739.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 739 after subtracting 0 from 739.
Append the next digit (8) from the dividend to 739 and continue with: 7398 / 990

Going ahead to step 4:
If we divide 7398 by 990, we get 7 and a remainder of 468.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 468 after subtracting 6930 from 7398.
Include the next digit (7) from the dividend after 468, then repeat: 4687 / 990

Going ahead to step 5:
990 goes into 4687 4 times with a remainder of 727.
The number 4 becomes the next digit in our result. 
Result so far: 74.0
Deduct 3960 from 4687 and we're left with 727.
Include the next digit (4) from the dividend after 727, then repeat: 7274 / 990

Moving on to step 6:
990 can be fit into 7274 7 times, resulting in a remainder of 344.
The next digit of our result is 7. 
Result so far: 747.0
If we subtract 6930 from 7274, we get 344.
Include the next digit (6) from the dividend after 344, then repeat: 3446 / 990

Let's proceed to step 7:
The number 990 fits into 3446 3 times, leaving a remainder of 476.
The number 3 becomes the next digit in our result. 
Result so far: 7473.0
The remainder is 476 after subtracting 2970 from 3446.
Take the next digit (5) from the dividend and append it to 476, then repeat: 4765 / 990

On to step 8:
4765 divided by 990 is 4 with a remainder of 805.
Use 4 as the next digit of our solution. 
Result so far: 74734.0
Deduct 3960 from 4765 and we're left with 805.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8050, and continue the process.

On to step 9:
If we divide 8050 by 990, we get 8 and a remainder of 130.
Write down 8 as next digit of the result. 
Result so far: 74734.8
Deduct 7920 from 8050 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 10:
If we divide 1300 by 990, we get 1 and a remainder of 310.
Record the quotient 1 as the next digit in the result. 
Result so far: 74734.81
If we subtract 990 from 1300, we get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Advancing to step 11:
If we divide 3100 by 990, we get 3 and a remainder of 130.
Use 3 as the next digit of our solution. 
Result so far: 74734.813
If we take 2970 away from 3100, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 12:
When dividing 1300 by 990, we get 1 with a remainder of 310.
Record the quotient 1 as the next digit in the result. 
Result so far: 74734.8131
If we subtract 990 from 1300, we get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Let's proceed to step 13:
990 can be fit into 3100 3 times, resulting in a remainder of 130.
Use 3 as the next digit of our solution. 
Result so far: 74734.81313
Subtracting 2970 from 3100 leaves us with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Step 14:
If we divide 1300 by 990, we get 1 and a remainder of 310.
The next digit of our result is 1. 
Result so far: 74734.813131
If we subtract 990 from 1300, we get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Going ahead to step 15:
If we divide 3100 by 990, we get 3 and a remainder of 130.
Record the quotient 3 as the next digit in the result. 
Result so far: 74734.8131313
Subtract 2970 from 3100 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 16:
The number 990 fits into 1300 1 times, leaving a remainder of 310.
Record the quotient 1 as the next digit in the result. 
Result so far: 74734.81313131
If we take 990 away from 1300, we end up with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

After the division, we end up with 74734.81313131 and a remainder of 3.1e-07.
