80673403 ÷ 988 
Our goal is to divide 80673403 by 988.

Let's proceed to step 1:
988 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 988

Moving on to step 2:
If we divide 80 by 988, we get 0 and a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Bring next digit (6) of the dividend behind the 80 and repeat the process: 806 / 988

On to step 3:
If we divide 806 by 988, we get 0 and a remainder of 806.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 806 leaves us with 806.
Include the next digit (7) from the dividend after 806, then repeat: 8067 / 988

Going ahead to step 4:
988 can be fit into 8067 8 times, resulting in a remainder of 163.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 7904 from 8067 to get 163.
Grab the next digit (3) from the dividend, add it to 163, then carry on: 1633 / 988

Going ahead to step 5:
If we divide 1633 by 988, we get 1 and a remainder of 645.
Record the quotient 1 as the next digit in the result. 
Result so far: 81.0
Subtract 988 from 1633 to get 645.
Fetch the next digit (4) from the dividend, attach it to 645 and continue: 6454 / 988

Moving on to step 6:
The number 988 fits into 6454 6 times, leaving a remainder of 526.
Use 6 as the next digit of our solution. 
Result so far: 816.0
Subtract 5928 from 6454 to get 526.
Append the next digit (0) from the dividend to 526 and continue with: 5260 / 988

Moving on to step 7:
5260 divided by 988 is 5 with a remainder of 320.
The number 5 becomes the next digit in our result. 
Result so far: 8165.0
The remainder is 320 after subtracting 4940 from 5260.
Include the next digit (3) from the dividend after 320, then repeat: 3203 / 988

Moving on to step 8:
988 goes into 3203 3 times with a remainder of 239.
Put 3 as the next digit of the answer. 
Result so far: 81653.0
Subtract 2964 from 3203 to get 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Advancing to step 9:
When dividing 2390 by 988, we get 2 with a remainder of 414.
The next digit of our result is 2. 
Result so far: 81653.2
Subtracting 1976 from 2390 leaves us with 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Going ahead to step 10:
988 can be fit into 4140 4 times, resulting in a remainder of 188.
The next digit of our result is 4. 
Result so far: 81653.24
If we subtract 3952 from 4140, we get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Let's proceed to step 11:
When dividing 1880 by 988, we get 1 with a remainder of 892.
Record the quotient 1 as the next digit in the result. 
Result so far: 81653.241
Deduct 988 from 1880 and we're left with 892.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8920, and continue the process.

On to step 12:
8920 divided by 988 is 9 with a remainder of 28.
Record the quotient 9 as the next digit in the result. 
Result so far: 81653.2419
Subtract 8892 from 8920 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 13:
The number 988 fits into 280 0 times, leaving a remainder of 280.
Put 0 as the next digit of the answer. 
Result so far: 81653.2419
Deduct 0 from 280 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 14:
988 goes into 2800 2 times with a remainder of 824.
Write down 2 as next digit of the result. 
Result so far: 81653.241902
The remainder is 824 after subtracting 1976 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8240, and continue the process.

Let's proceed to step 15:
8240 divided by 988 is 8 with a remainder of 336.
Write down 8 as next digit of the result. 
Result so far: 81653.2419028
If we take 7904 away from 8240, we end up with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Let's proceed to step 16:
If we divide 3360 by 988, we get 3 and a remainder of 396.
Put 3 as the next digit of the answer. 
Result so far: 81653.24190283
If we take 2964 away from 3360, we end up with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

The final result is 81653.24190283 with a remainder of 3.96e-07.
