75390644 ÷ 959 
Let's see how many times 959 fits into 75390644.

Going ahead to step 1:
7 divided by 959 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 959

On to step 2:
If we divide 75 by 959, we get 0 and a remainder of 75.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 75 and we're left with 75.
Include the next digit (3) from the dividend after 75, then repeat: 753 / 959

Let's proceed to step 3:
753 divided by 959 is 0 with a remainder of 753.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 753, we get 753.
Fetch the next digit (9) from the dividend, attach it to 753 and continue: 7539 / 959

Step 4:
When dividing 7539 by 959, we get 7 with a remainder of 826.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 6713 away from 7539, we end up with 826.
Grab the next digit (0) from the dividend, add it to 826, then carry on: 8260 / 959

On to step 5:
959 can be fit into 8260 8 times, resulting in a remainder of 588.
Write down 8 as next digit of the result. 
Result so far: 78.0
Subtract 7672 from 8260 to get 588.
Bring next digit (6) of the dividend behind the 588 and repeat the process: 5886 / 959

Step 6:
The number 959 fits into 5886 6 times, leaving a remainder of 132.
The number 6 becomes the next digit in our result. 
Result so far: 786.0
Deduct 5754 from 5886 and we're left with 132.
Include the next digit (4) from the dividend after 132, then repeat: 1324 / 959

Going ahead to step 7:
959 can be fit into 1324 1 times, resulting in a remainder of 365.
Write down 1 as next digit of the result. 
Result so far: 7861.0
Deduct 959 from 1324 and we're left with 365.
Bring next digit (4) of the dividend behind the 365 and repeat the process: 3654 / 959

Advancing to step 8:
959 goes into 3654 3 times with a remainder of 777.
The next digit of our result is 3. 
Result so far: 78613.0
Subtract 2877 from 3654 to get 777.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7770, and continue the process.

Moving on to step 9:
959 goes into 7770 8 times with a remainder of 98.
The next digit of our result is 8. 
Result so far: 78613.8
If we subtract 7672 from 7770, we get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Going ahead to step 10:
When dividing 980 by 959, we get 1 with a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 78613.81
If we subtract 959 from 980, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 11:
When dividing 210 by 959, we get 0 with a remainder of 210.
Use 0 as the next digit of our solution. 
Result so far: 78613.81
Subtract 0 from 210 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Step 12:
2100 divided by 959 is 2 with a remainder of 182.
Write down 2 as next digit of the result. 
Result so far: 78613.8102
The remainder is 182 after subtracting 1918 from 2100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Step 13:
If we divide 1820 by 959, we get 1 and a remainder of 861.
Record the quotient 1 as the next digit in the result. 
Result so far: 78613.81021
If we subtract 959 from 1820, we get 861.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8610, and continue the process.

Going ahead to step 14:
When dividing 8610 by 959, we get 8 with a remainder of 938.
Write down 8 as next digit of the result. 
Result so far: 78613.810218
If we take 7672 away from 8610, we end up with 938.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9380, and continue the process.

Moving on to step 15:
If we divide 9380 by 959, we get 9 and a remainder of 749.
Use 9 as the next digit of our solution. 
Result so far: 78613.8102189
Deduct 8631 from 9380 and we're left with 749.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7490, and continue the process.

Moving on to step 16:
7490 divided by 959 is 7 with a remainder of 777.
Put 7 as the next digit of the answer. 
Result so far: 78613.81021897
The remainder is 777 after subtracting 6713 from 7490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7770, and continue the process.

The final outcome is 78613.81021897, with a leftover of 7.77e-07.
