We divide 78555391 by 197
Let's see how many times 197 fits into 78555391.

Let's proceed to step 1:
The number 197 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 197

Step 2:
197 can be fit into 78 0 times, resulting in a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Include the next digit (5) from the dividend after 78, then repeat: 785 / 197

On to step 3:
785 divided by 197 is 3 with a remainder of 194.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 591 from 785 leaves us with 194.
Bring next digit (5) of the dividend behind the 194 and repeat the process: 1945 / 197

Step 4:
The number 197 fits into 1945 9 times, leaving a remainder of 172.
Write down 9 as next digit of the result. 
Result so far: 39.0
The remainder is 172 after subtracting 1773 from 1945.
Fetch the next digit (5) from the dividend, attach it to 172 and continue: 1725 / 197

Going ahead to step 5:
The number 197 fits into 1725 8 times, leaving a remainder of 149.
Use 8 as the next digit of our solution. 
Result so far: 398.0
If we subtract 1576 from 1725, we get 149.
Append the next digit (3) from the dividend to 149 and continue with: 1493 / 197

Let's proceed to step 6:
The number 197 fits into 1493 7 times, leaving a remainder of 114.
Write down 7 as next digit of the result. 
Result so far: 3987.0
If we take 1379 away from 1493, we end up with 114.
Take the next digit (9) from the dividend and append it to 114, then repeat: 1149 / 197

Moving on to step 7:
When dividing 1149 by 197, we get 5 with a remainder of 164.
Record the quotient 5 as the next digit in the result. 
Result so far: 39875.0
Subtract 985 from 1149 to get 164.
Include the next digit (1) from the dividend after 164, then repeat: 1641 / 197

Moving on to step 8:
The number 197 fits into 1641 8 times, leaving a remainder of 65.
Use 8 as the next digit of our solution. 
Result so far: 398758.0
If we subtract 1576 from 1641, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 9:
When dividing 650 by 197, we get 3 with a remainder of 59.
Write down 3 as next digit of the result. 
Result so far: 398758.3
The remainder is 59 after subtracting 591 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 10:
197 can be fit into 590 2 times, resulting in a remainder of 196.
Use 2 as the next digit of our solution. 
Result so far: 398758.32
The remainder is 196 after subtracting 394 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Going ahead to step 11:
197 goes into 1960 9 times with a remainder of 187.
Use 9 as the next digit of our solution. 
Result so far: 398758.329
The remainder is 187 after subtracting 1773 from 1960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Advancing to step 12:
The number 197 fits into 1870 9 times, leaving a remainder of 97.
Put 9 as the next digit of the answer. 
Result so far: 398758.3299
Deduct 1773 from 1870 and we're left with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Our division results in 398758.3299 with a remaining 0.00097.
