75368899 ÷ 978 
Our goal is to divide 75368899 by 978.

Step 1:
978 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 978

Going ahead to step 2:
The number 978 fits into 75 0 times, leaving a remainder of 75.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 75, we get 75.
Bring next digit (3) of the dividend behind the 75 and repeat the process: 753 / 978

Going ahead to step 3:
When dividing 753 by 978, we get 0 with a remainder of 753.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 753, we get 753.
Fetch the next digit (6) from the dividend, attach it to 753 and continue: 7536 / 978

Moving on to step 4:
When dividing 7536 by 978, we get 7 with a remainder of 690.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 690 after subtracting 6846 from 7536.
Bring next digit (8) of the dividend behind the 690 and repeat the process: 6908 / 978

Going ahead to step 5:
6908 divided by 978 is 7 with a remainder of 62.
The next digit of our result is 7. 
Result so far: 77.0
Subtract 6846 from 6908 to get 62.
Append the next digit (8) from the dividend to 62 and continue with: 628 / 978

Step 6:
978 can be fit into 628 0 times, resulting in a remainder of 628.
The next digit of our result is 0. 
Result so far: 770.0
Subtracting 0 from 628 leaves us with 628.
Bring next digit (9) of the dividend behind the 628 and repeat the process: 6289 / 978

Moving on to step 7:
If we divide 6289 by 978, we get 6 and a remainder of 421.
The next digit of our result is 6. 
Result so far: 7706.0
The remainder is 421 after subtracting 5868 from 6289.
Take the next digit (9) from the dividend and append it to 421, then repeat: 4219 / 978

Moving on to step 8:
4219 divided by 978 is 4 with a remainder of 307.
Record the quotient 4 as the next digit in the result. 
Result so far: 77064.0
Subtract 3912 from 4219 to get 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

Going ahead to step 9:
3070 divided by 978 is 3 with a remainder of 136.
Use 3 as the next digit of our solution. 
Result so far: 77064.3
Deduct 2934 from 3070 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Going ahead to step 10:
978 can be fit into 1360 1 times, resulting in a remainder of 382.
Write down 1 as next digit of the result. 
Result so far: 77064.31
If we take 978 away from 1360, we end up with 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Advancing to step 11:
The number 978 fits into 3820 3 times, leaving a remainder of 886.
Put 3 as the next digit of the answer. 
Result so far: 77064.313
If we take 2934 away from 3820, we end up with 886.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8860, and continue the process.

Step 12:
If we divide 8860 by 978, we get 9 and a remainder of 58.
Put 9 as the next digit of the answer. 
Result so far: 77064.3139
If we take 8802 away from 8860, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 13:
978 can be fit into 580 0 times, resulting in a remainder of 580.
Write down 0 as next digit of the result. 
Result so far: 77064.3139
If we subtract 0 from 580, we get 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

On to step 14:
When dividing 5800 by 978, we get 5 with a remainder of 910.
Write down 5 as next digit of the result. 
Result so far: 77064.313905
Deduct 4890 from 5800 and we're left with 910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9100, and continue the process.

Let's proceed to step 15:
When dividing 9100 by 978, we get 9 with a remainder of 298.
Record the quotient 9 as the next digit in the result. 
Result so far: 77064.3139059
Deduct 8802 from 9100 and we're left with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Moving on to step 16:
2980 divided by 978 is 3 with a remainder of 46.
The number 3 becomes the next digit in our result. 
Result so far: 77064.31390593
If we take 2934 away from 2980, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The final result is 77064.31390593 with a remainder of 4.6e-08.
