We're dividing 99174171 by 245 
Our goal is to divide 99174171 by 245.

Let's proceed to step 1:
When dividing 9 by 245, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 245

Let's proceed to step 2:
245 goes into 99 0 times with a remainder of 99.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 99 after subtracting 0 from 99.
Include the next digit (1) from the dividend after 99, then repeat: 991 / 245

On to step 3:
When dividing 991 by 245, we get 4 with a remainder of 11.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 980 from 991 to get 11.
Append the next digit (7) from the dividend to 11 and continue with: 117 / 245

Step 4:
The number 245 fits into 117 0 times, leaving a remainder of 117.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
Deduct 0 from 117 and we're left with 117.
Take the next digit (4) from the dividend and append it to 117, then repeat: 1174 / 245

On to step 5:
When dividing 1174 by 245, we get 4 with a remainder of 194.
Record the quotient 4 as the next digit in the result. 
Result so far: 404.0
Subtract 980 from 1174 to get 194.
Bring next digit (1) of the dividend behind the 194 and repeat the process: 1941 / 245

Moving on to step 6:
245 goes into 1941 7 times with a remainder of 226.
Use 7 as the next digit of our solution. 
Result so far: 4047.0
Deduct 1715 from 1941 and we're left with 226.
Grab the next digit (7) from the dividend, add it to 226, then carry on: 2267 / 245

Going ahead to step 7:
When dividing 2267 by 245, we get 9 with a remainder of 62.
Record the quotient 9 as the next digit in the result. 
Result so far: 40479.0
Deduct 2205 from 2267 and we're left with 62.
Include the next digit (1) from the dividend after 62, then repeat: 621 / 245

On to step 8:
621 divided by 245 is 2 with a remainder of 131.
Put 2 as the next digit of the answer. 
Result so far: 404792.0
If we subtract 490 from 621, we get 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Advancing to step 9:
245 can be fit into 1310 5 times, resulting in a remainder of 85.
Record the quotient 5 as the next digit in the result. 
Result so far: 404792.5
The remainder is 85 after subtracting 1225 from 1310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

On to step 10:
245 can be fit into 850 3 times, resulting in a remainder of 115.
Record the quotient 3 as the next digit in the result. 
Result so far: 404792.53
Subtract 735 from 850 to get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Going ahead to step 11:
If we divide 1150 by 245, we get 4 and a remainder of 170.
Record the quotient 4 as the next digit in the result. 
Result so far: 404792.534
Subtracting 980 from 1150 leaves us 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.

Advancing to step 12:
245 goes into 1700 6 times with a remainder of 230.
Write down 6 as next digit of the result. 
Result so far: 404792.5346
The remainder is 230 after subtracting 1470 from 1700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 13:
245 can be fit into 2300 9 times, resulting in a remainder of 95.
Put 9 as the next digit of the answer. 
Result so far: 404792.53469
If we take 2205 away from 2300, we end up with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Step 14:
950 divided by 245 is 3 with a remainder of 215.
The number 3 becomes the next digit in our result. 
Result so far: 404792.534693
The remainder is 215 after subtracting 735 from 950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Step 15:
If we divide 2150 by 245, we get 8 and a remainder of 190.
Put 8 as the next digit of the answer. 
Result so far: 404792.5346938
Subtracting 1960 from 2150 leaves us with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Let's proceed to step 16:
If we divide 1900 by 245, we get 7 and a remainder of 185.
Put 7 as the next digit of the answer. 
Result so far: 404792.53469387
If we take 1715 away from 1900, we end up with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

The final outcome is 404792.53469387, with a leftover of 1.85e-07.
