20357198 ÷ 261 
We want to figure out the number of times 20357198 can be divided by 261.

Advancing to step 1:
261 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 261

Let's proceed to step 2:
261 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Grab the next digit (3) from the dividend, add it to 20, then carry on: 203 / 261

Advancing to step 3:
If we divide 203 by 261, we get 0 and a remainder of 203.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 203 and we're left with 203.
Append the next digit (5) from the dividend to 203 and continue with: 2035 / 261

On to step 4:
When dividing 2035 by 261, we get 7 with a remainder of 208.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we take 1827 away from 2035, we end up with 208.
Grab the next digit (7) from the dividend, add it to 208, then carry on: 2087 / 261

Moving on to step 5:
If we divide 2087 by 261, we get 7 and a remainder of 260.
Write down 7 as next digit of the result. 
Result so far: 77.0
Deduct 1827 from 2087 and we're left with 260.
Append the next digit (1) from the dividend to 260 and continue with: 2601 / 261

Let's proceed to step 6:
261 goes into 2601 9 times with a remainder of 252.
Write down 9 as next digit of the result. 
Result so far: 779.0
If we take 2349 away from 2601, we end up with 252.
Bring next digit (9) of the dividend behind the 252 and repeat the process: 2529 / 261

Step 7:
2529 divided by 261 is 9 with a remainder of 180.
The number 9 becomes the next digit in our result. 
Result so far: 7799.0
If we take 2349 away from 2529, we end up with 180.
Fetch the next digit (8) from the dividend, attach it to 180 and continue: 1808 / 261

Advancing to step 8:
261 can be fit into 1808 6 times, resulting in a remainder of 242.
Write down 6 as next digit of the result. 
Result so far: 77996.0
Subtracting 1566 from 1808 leaves us with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Step 9:
If we divide 2420 by 261, we get 9 and a remainder of 71.
The next digit of our result is 9. 
Result so far: 77996.9
If we take 2349 away from 2420, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 10:
261 can be fit into 710 2 times, resulting in a remainder of 188.
Record the quotient 2 as the next digit in the result. 
Result so far: 77996.92
If we subtract 522 from 710, we get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Moving on to step 11:
261 goes into 1880 7 times with a remainder of 53.
The number 7 becomes the next digit in our result. 
Result so far: 77996.927
If we subtract 1827 from 1880, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 12:
261 goes into 530 2 times with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 77996.9272
Deduct 522 from 530 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 13:
261 goes into 80 0 times with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 77996.9272
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 14:
261 can be fit into 800 3 times, resulting in a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 77996.927203
Deduct 783 from 800 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 15:
If we divide 170 by 261, we get 0 and a remainder of 170.
Put 0 as the next digit of the answer. 
Result so far: 77996.927203
Deduct 0 from 170 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Going ahead to step 16:
If we divide 1700 by 261, we get 6 and a remainder of 134.
Record the quotient 6 as the next digit in the result. 
Result so far: 77996.92720306
The remainder is 134 after subtracting 1566 from 1700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

In conclusion, the division gives 77996.92720306 with a balance of 1.34e-07.
