80835643 divided by 107 
Let's see how many times 107 fits into 80835643.

Advancing to step 1:
When dividing 8 by 107, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 107

Moving on to step 2:
The number 107 fits into 80 0 times, leaving a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Take the next digit (8) from the dividend and append it to 80, then repeat: 808 / 107

On to step 3:
107 goes into 808 7 times with a remainder of 59.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 749 from 808 and we're left with 59.
Fetch the next digit (3) from the dividend, attach it to 59 and continue: 593 / 107

Advancing to step 4:
593 divided by 107 is 5 with a remainder of 58.
Record the quotient 5 as the next digit in the result. 
Result so far: 75.0
Subtract 535 from 593 to get 58.
Fetch the next digit (5) from the dividend, attach it to 58 and continue: 585 / 107

Let's proceed to step 5:
107 can be fit into 585 5 times, resulting in a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 755.0
Deduct 535 from 585 and we're left with 50.
Take the next digit (6) from the dividend and append it to 50, then repeat: 506 / 107

Moving on to step 6:
107 can be fit into 506 4 times, resulting in a remainder of 78.
Record the quotient 4 as the next digit in the result. 
Result so far: 7554.0
If we subtract 428 from 506, we get 78.
Include the next digit (4) from the dividend after 78, then repeat: 784 / 107

Advancing to step 7:
784 divided by 107 is 7 with a remainder of 35.
Put 7 as the next digit of the answer. 
Result so far: 75547.0
If we subtract 749 from 784, we get 35.
Include the next digit (3) from the dividend after 35, then repeat: 353 / 107

Going ahead to step 8:
353 divided by 107 is 3 with a remainder of 32.
Record the quotient 3 as the next digit in the result. 
Result so far: 755473.0
The remainder is 32 after subtracting 321 from 353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 9:
107 can be fit into 320 2 times, resulting in a remainder of 106.
The next digit of our result is 2. 
Result so far: 755473.2
If we take 214 away from 320, we end up with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Step 10:
If we divide 1060 by 107, we get 9 and a remainder of 97.
Write down 9 as next digit of the result. 
Result so far: 755473.29
Subtract 963 from 1060 to get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Let's proceed to step 11:
If we divide 970 by 107, we get 9 and a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 755473.299
Subtracting 963 from 970 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

After the division, we end up with 755473.299 and a remainder of 0.0007.
