Let's divide 51308860 by 902
We want to figure out the number of times 51308860 can be divided by 902.

Let's proceed to step 1:
902 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 902

Going ahead to step 2:
When dividing 51 by 902, we get 0 with a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Append the next digit (3) from the dividend to 51 and continue with: 513 / 902

On to step 3:
The number 902 fits into 513 0 times, leaving a remainder of 513.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 513 and we're left with 513.
Fetch the next digit (0) from the dividend, attach it to 513 and continue: 5130 / 902

Let's proceed to step 4:
902 can be fit into 5130 5 times, resulting in a remainder of 620.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 4510 from 5130 to get 620.
Bring next digit (8) of the dividend behind the 620 and repeat the process: 6208 / 902

Let's proceed to step 5:
902 can be fit into 6208 6 times, resulting in a remainder of 796.
Record the quotient 6 as the next digit in the result. 
Result so far: 56.0
Subtracting 5412 from 6208 leaves us with 796.
Take the next digit (8) from the dividend and append it to 796, then repeat: 7968 / 902

Moving on to step 6:
When dividing 7968 by 902, we get 8 with a remainder of 752.
Record the quotient 8 as the next digit in the result. 
Result so far: 568.0
Subtract 7216 from 7968 to get 752.
Grab the next digit (6) from the dividend, add it to 752, then carry on: 7526 / 902

Moving on to step 7:
7526 divided by 902 is 8 with a remainder of 310.
Write down 8 as next digit of the result. 
Result so far: 5688.0
Subtract 7216 from 7526 to get 310.
Append the next digit (0) from the dividend to 310 and continue with: 3100 / 902

Advancing to step 8:
If we divide 3100 by 902, we get 3 and a remainder of 394.
Put 3 as the next digit of the answer. 
Result so far: 56883.0
Subtract 2706 from 3100 to get 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Step 9:
If we divide 3940 by 902, we get 4 and a remainder of 332.
The number 4 becomes the next digit in our result. 
Result so far: 56883.4
The remainder is 332 after subtracting 3608 from 3940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

On to step 10:
If we divide 3320 by 902, we get 3 and a remainder of 614.
Use 3 as the next digit of our solution. 
Result so far: 56883.43
Subtracting 2706 from 3320 leaves us with 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

On to step 11:
When dividing 6140 by 902, we get 6 with a remainder of 728.
Use 6 as the next digit of our solution. 
Result so far: 56883.436
Subtracting 5412 from 6140 leaves us with 728.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7280, and continue the process.

Step 12:
The number 902 fits into 7280 8 times, leaving a remainder of 64.
The next digit of our result is 8. 
Result so far: 56883.4368
Subtract 7216 from 7280 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 13:
If we divide 640 by 902, we get 0 and a remainder of 640.
Record the quotient 0 as the next digit in the result. 
Result so far: 56883.4368
If we take 0 away from 640, we end up with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Moving on to step 14:
When dividing 6400 by 902, we get 7 with a remainder of 86.
Put 7 as the next digit of the answer. 
Result so far: 56883.436807
Subtract 6314 from 6400 to get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Moving on to step 15:
If we divide 860 by 902, we get 0 and a remainder of 860.
Put 0 as the next digit of the answer. 
Result so far: 56883.436807
Deduct 0 from 860 and we're left with 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8600, and continue the process.

Moving on to step 16:
902 goes into 8600 9 times with a remainder of 482.
The next digit of our result is 9. 
Result so far: 56883.43680709
Deduct 8118 from 8600 and we're left with 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

The final outcome is 56883.43680709, with a leftover of 4.82e-07.
