75139508 divided by 977 
Let's see how many times 977 fits into 75139508.

Moving on to step 1:
977 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 977

Going ahead to step 2:
977 can be fit into 75 0 times, resulting in a remainder of 75.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 75 to get 75.
Fetch the next digit (1) from the dividend, attach it to 75 and continue: 751 / 977

Advancing to step 3:
If we divide 751 by 977, we get 0 and a remainder of 751.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 751 to get 751.
Take the next digit (3) from the dividend and append it to 751, then repeat: 7513 / 977

On to step 4:
The number 977 fits into 7513 7 times, leaving a remainder of 674.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 6839 from 7513 and we're left with 674.
Bring next digit (9) of the dividend behind the 674 and repeat the process: 6749 / 977

Step 5:
If we divide 6749 by 977, we get 6 and a remainder of 887.
Write down 6 as next digit of the result. 
Result so far: 76.0
Subtract 5862 from 6749 to get 887.
Append the next digit (5) from the dividend to 887 and continue with: 8875 / 977

Let's proceed to step 6:
If we divide 8875 by 977, we get 9 and a remainder of 82.
The next digit of our result is 9. 
Result so far: 769.0
If we subtract 8793 from 8875, we get 82.
Append the next digit (0) from the dividend to 82 and continue with: 820 / 977

Step 7:
When dividing 820 by 977, we get 0 with a remainder of 820.
Use 0 as the next digit of our solution. 
Result so far: 7690.0
Subtract 0 from 820 to get 820.
Take the next digit (8) from the dividend and append it to 820, then repeat: 8208 / 977

Going ahead to step 8:
When dividing 8208 by 977, we get 8 with a remainder of 392.
The number 8 becomes the next digit in our result. 
Result so far: 76908.0
If we subtract 7816 from 8208, we get 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Let's proceed to step 9:
When dividing 3920 by 977, we get 4 with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 76908.4
The remainder is 12 after subtracting 3908 from 3920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 10:
If we divide 120 by 977, we get 0 and a remainder of 120.
Record the quotient 0 as the next digit in the result. 
Result so far: 76908.4
Deduct 0 from 120 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 11:
977 goes into 1200 1 times with a remainder of 223.
Write down 1 as next digit of the result. 
Result so far: 76908.401
If we take 977 away from 1200, we end up with 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

Going ahead to step 12:
When dividing 2230 by 977, we get 2 with a remainder of 276.
Record the quotient 2 as the next digit in the result. 
Result so far: 76908.4012
Subtracting 1954 from 2230 leaves us with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Moving on to step 13:
2760 divided by 977 is 2 with a remainder of 806.
The number 2 becomes the next digit in our result. 
Result so far: 76908.40122
If we subtract 1954 from 2760, we get 806.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8060, and continue the process.

The final outcome is 76908.40122, with a leftover of 0.000806.
