75620821 ÷ 261 
Our goal is to divide 75620821 by 261.

Moving on to step 1:
The number 261 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 261

On to step 2:
The number 261 fits into 75 0 times, leaving a remainder of 75.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 75 leaves us with 75.
Grab the next digit (6) from the dividend, add it to 75, then carry on: 756 / 261

Moving on to step 3:
756 divided by 261 is 2 with a remainder of 234.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 522 from 756, we get 234.
Fetch the next digit (2) from the dividend, attach it to 234 and continue: 2342 / 261

Advancing to step 4:
261 goes into 2342 8 times with a remainder of 254.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
If we subtract 2088 from 2342, we get 254.
Bring next digit (0) of the dividend behind the 254 and repeat the process: 2540 / 261

Let's proceed to step 5:
2540 divided by 261 is 9 with a remainder of 191.
Use 9 as the next digit of our solution. 
Result so far: 289.0
Deduct 2349 from 2540 and we're left with 191.
Take the next digit (8) from the dividend and append it to 191, then repeat: 1918 / 261

Moving on to step 6:
261 can be fit into 1918 7 times, resulting in a remainder of 91.
The number 7 becomes the next digit in our result. 
Result so far: 2897.0
If we take 1827 away from 1918, we end up with 91.
Include the next digit (2) from the dividend after 91, then repeat: 912 / 261

Let's proceed to step 7:
261 can be fit into 912 3 times, resulting in a remainder of 129.
Write down 3 as next digit of the result. 
Result so far: 28973.0
Subtract 783 from 912 to get 129.
Include the next digit (1) from the dividend after 129, then repeat: 1291 / 261

Going ahead to step 8:
When dividing 1291 by 261, we get 4 with a remainder of 247.
The next digit of our result is 4. 
Result so far: 289734.0
The remainder is 247 after subtracting 1044 from 1291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Let's proceed to step 9:
If we divide 2470 by 261, we get 9 and a remainder of 121.
The next digit of our result is 9. 
Result so far: 289734.9
Subtract 2349 from 2470 to get 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Step 10:
261 goes into 1210 4 times with a remainder of 166.
The next digit of our result is 4. 
Result so far: 289734.94
If we subtract 1044 from 1210, we get 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Let's proceed to step 11:
1660 divided by 261 is 6 with a remainder of 94.
The number 6 becomes the next digit in our result. 
Result so far: 289734.946
Deduct 1566 from 1660 and we're left with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Going ahead to step 12:
The number 261 fits into 940 3 times, leaving a remainder of 157.
Record the quotient 3 as the next digit in the result. 
Result so far: 289734.9463
Subtracting 783 from 940 leaves us with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Going ahead to step 13:
The number 261 fits into 1570 6 times, leaving a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 289734.94636
The remainder is 4 after subtracting 1566 from 1570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 14:
261 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 289734.94636
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 15:
400 divided by 261 is 1 with a remainder of 139.
The number 1 becomes the next digit in our result. 
Result so far: 289734.9463601
Subtracting 261 from 400 leaves us with 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Advancing to step 16:
The number 261 fits into 1390 5 times, leaving a remainder of 85.
The number 5 becomes the next digit in our result. 
Result so far: 289734.94636015
If we subtract 1305 from 1390, 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.

The final outcome is 289734.94636015, with a leftover of 8.5e-08.
