Let's divide 51397365 by 655
Let's see how many times 655 fits into 51397365.

Going ahead to step 1:
5 divided by 655 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 655

Step 2:
When dividing 51 by 655, we get 0 with a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Bring next digit (3) of the dividend behind the 51 and repeat the process: 513 / 655

Moving on to step 3:
655 goes into 513 0 times with a remainder of 513.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 513, we end up with 513.
Append the next digit (9) from the dividend to 513 and continue with: 5139 / 655

On to step 4:
5139 divided by 655 is 7 with a remainder of 554.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 4585 from 5139, we get 554.
Bring next digit (7) of the dividend behind the 554 and repeat the process: 5547 / 655

Let's proceed to step 5:
The number 655 fits into 5547 8 times, leaving a remainder of 307.
Put 8 as the next digit of the answer. 
Result so far: 78.0
Subtracting 5240 from 5547 leaves us with 307.
Grab the next digit (3) from the dividend, add it to 307, then carry on: 3073 / 655

On to step 6:
655 goes into 3073 4 times with a remainder of 453.
Use 4 as the next digit of our solution. 
Result so far: 784.0
Subtracting 2620 from 3073 leaves us with 453.
Take the next digit (6) from the dividend and append it to 453, then repeat: 4536 / 655

Moving on to step 7:
655 can be fit into 4536 6 times, resulting in a remainder of 606.
The next digit of our result is 6. 
Result so far: 7846.0
The remainder is 606 after subtracting 3930 from 4536.
Append the next digit (5) from the dividend to 606 and continue with: 6065 / 655

Advancing to step 8:
6065 divided by 655 is 9 with a remainder of 170.
Use 9 as the next digit of our solution. 
Result so far: 78469.0
Subtract 5895 from 6065 to get 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 9:
1700 divided by 655 is 2 with a remainder of 390.
Use 2 as the next digit of our solution. 
Result so far: 78469.2
Deduct 1310 from 1700 and we're left with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Let's proceed to step 10:
The number 655 fits into 3900 5 times, leaving a remainder of 625.
Write down 5 as next digit of the result. 
Result so far: 78469.25
Deduct 3275 from 3900 and we're left with 625.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6250, and continue the process.

Going ahead to step 11:
If we divide 6250 by 655, we get 9 and a remainder of 355.
Use 9 as the next digit of our solution. 
Result so far: 78469.259
Subtract 5895 from 6250 to get 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Let's proceed to step 12:
The number 655 fits into 3550 5 times, leaving a remainder of 275.
The number 5 becomes the next digit in our result. 
Result so far: 78469.2595
Deduct 3275 from 3550 and we're left with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Advancing to step 13:
The number 655 fits into 2750 4 times, leaving a remainder of 130.
Record the quotient 4 as the next digit in the result. 
Result so far: 78469.25954
The remainder is 130 after subtracting 2620 from 2750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 14:
When dividing 1300 by 655, we get 1 with a remainder of 645.
The next digit of our result is 1. 
Result so far: 78469.259541
Deduct 655 from 1300 and we're left with 645.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6450, and continue the process.

Going ahead to step 15:
655 goes into 6450 9 times with a remainder of 555.
Put 9 as the next digit of the answer. 
Result so far: 78469.2595419
Deduct 5895 from 6450 and we're left with 555.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

Moving on to step 16:
The number 655 fits into 5550 8 times, leaving a remainder of 310.
The next digit of our result is 8. 
Result so far: 78469.25954198
If we subtract 5240 from 5550, we get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

The final outcome is 78469.25954198, with a leftover of 3.1e-07.
