Let's divide 75507437 by 109
We're looking to find how many times 109 goes into 75507437.

Going ahead to step 1:
If we divide 7 by 109, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 109

Advancing to step 2:
The number 109 fits into 75 0 times, leaving a remainder of 75.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 75 to get 75.
Fetch the next digit (5) from the dividend, attach it to 75 and continue: 755 / 109

Going ahead to step 3:
If we divide 755 by 109, we get 6 and a remainder of 101.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 654 from 755 and we're left with 101.
Include the next digit (0) from the dividend after 101, then repeat: 1010 / 109

Step 4:
If we divide 1010 by 109, we get 9 and a remainder of 29.
Put 9 as the next digit of the answer. 
Result so far: 69.0
Subtracting 981 from 1010 leaves us with 29.
Grab the next digit (7) from the dividend, add it to 29, then carry on: 297 / 109

Moving on to step 5:
If we divide 297 by 109, we get 2 and a remainder of 79.
The next digit of our result is 2. 
Result so far: 692.0
The remainder is 79 after subtracting 218 from 297.
Take the next digit (4) from the dividend and append it to 79, then repeat: 794 / 109

Moving on to step 6:
When dividing 794 by 109, we get 7 with a remainder of 31.
Put 7 as the next digit of the answer. 
Result so far: 6927.0
Deduct 763 from 794 and we're left with 31.
Bring next digit (3) of the dividend behind the 31 and repeat the process: 313 / 109

Advancing to step 7:
The number 109 fits into 313 2 times, leaving a remainder of 95.
The number 2 becomes the next digit in our result. 
Result so far: 69272.0
The remainder is 95 after subtracting 218 from 313.
Append the next digit (7) from the dividend to 95 and continue with: 957 / 109

Let's proceed to step 8:
If we divide 957 by 109, we get 8 and a remainder of 85.
The next digit of our result is 8. 
Result so far: 692728.0
If we subtract 872 from 957, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Let's proceed to step 9:
When dividing 850 by 109, we get 7 with a remainder of 87.
Write down 7 as next digit of the result. 
Result so far: 692728.7
Deduct 763 from 850 and we're left with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Going ahead to step 10:
870 divided by 109 is 7 with a remainder of 107.
Use 7 as the next digit of our solution. 
Result so far: 692728.77
If we take 763 away from 870, we end up with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

The final outcome is 692728.77, with a leftover of 0.107.
