51604661 divided by 245 
Let's see how many times 245 fits into 51604661.

Going ahead to step 1:
When dividing 5 by 245, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 245

Moving on to step 2:
245 goes into 51 0 times with a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Grab the next digit (6) from the dividend, add it to 51, then carry on: 516 / 245

Step 3:
245 can be fit into 516 2 times, resulting in a remainder of 26.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 490 from 516 leaves us with 26.
Grab the next digit (0) from the dividend, add it to 26, then carry on: 260 / 245

Let's proceed to step 4:
The number 245 fits into 260 1 times, leaving a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 21.0
Subtracting 245 from 260 leaves us with 15.
Include the next digit (4) from the dividend after 15, then repeat: 154 / 245

On to step 5:
When dividing 154 by 245, we get 0 with a remainder of 154.
Write down 0 as next digit of the result. 
Result so far: 210.0
The remainder is 154 after subtracting 0 from 154.
Grab the next digit (6) from the dividend, add it to 154, then carry on: 1546 / 245

Advancing to step 6:
The number 245 fits into 1546 6 times, leaving a remainder of 76.
Use 6 as the next digit of our solution. 
Result so far: 2106.0
Deduct 1470 from 1546 and we're left with 76.
Bring next digit (6) of the dividend behind the 76 and repeat the process: 766 / 245

Moving on to step 7:
245 can be fit into 766 3 times, resulting in a remainder of 31.
The number 3 becomes the next digit in our result. 
Result so far: 21063.0
Subtract 735 from 766 to get 31.
Fetch the next digit (1) from the dividend, attach it to 31 and continue: 311 / 245

Going ahead to step 8:
245 can be fit into 311 1 times, resulting in a remainder of 66.
The next digit of our result is 1. 
Result so far: 210631.0
If we take 245 away from 311, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 9:
The number 245 fits into 660 2 times, leaving a remainder of 170.
Write down 2 as next digit of the result. 
Result so far: 210631.2
Deduct 490 from 660 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.

Advancing to step 10:
When dividing 1700 by 245, we get 6 with a remainder of 230.
Put 6 as the next digit of the answer. 
Result so far: 210631.26
If we take 1470 away from 1700, we end up with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

On to step 11:
2300 divided by 245 is 9 with a remainder of 95.
Use 9 as the next digit of our solution. 
Result so far: 210631.269
Subtracting 2205 from 2300 leaves us 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.

Going ahead to step 12:
245 can be fit into 950 3 times, resulting in a remainder of 215.
Use 3 as the next digit of our solution. 
Result so far: 210631.2693
If we subtract 735 from 950, we get 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Going ahead to step 13:
245 can be fit into 2150 8 times, resulting in a remainder of 190.
The number 8 becomes the next digit in our result. 
Result so far: 210631.26938
The remainder is 190 after subtracting 1960 from 2150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Going ahead to step 14:
If we divide 1900 by 245, we get 7 and a remainder of 185.
Write down 7 as next digit of the result. 
Result so far: 210631.269387
Subtract 1715 from 1900 to get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Advancing to step 15:
1850 divided by 245 is 7 with a remainder of 135.
Put 7 as the next digit of the answer. 
Result so far: 210631.2693877
If we take 1715 away from 1850, we end up with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

The final result is 210631.2693877 with a remainder of 1.35e-06.
