We're dividing 51145929 by 902 
The aim is to understand the frequency of 902 in 51145929.

Let's proceed to step 1:
902 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 902

Moving on to step 2:
When dividing 51 by 902, we get 0 with a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Grab the next digit (1) from the dividend, add it to 51, then carry on: 511 / 902

Moving on to step 3:
When dividing 511 by 902, we get 0 with a remainder of 511.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 511 to get 511.
Include the next digit (4) from the dividend after 511, then repeat: 5114 / 902

Step 4:
902 can be fit into 5114 5 times, resulting in a remainder of 604.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 4510 from 5114 and we're left with 604.
Append the next digit (5) from the dividend to 604 and continue with: 6045 / 902

On to step 5:
If we divide 6045 by 902, we get 6 and a remainder of 633.
Put 6 as the next digit of the answer. 
Result so far: 56.0
The remainder is 633 after subtracting 5412 from 6045.
Fetch the next digit (9) from the dividend, attach it to 633 and continue: 6339 / 902

Step 6:
If we divide 6339 by 902, we get 7 and a remainder of 25.
Record the quotient 7 as the next digit in the result. 
Result so far: 567.0
If we take 6314 away from 6339, we end up with 25.
Grab the next digit (2) from the dividend, add it to 25, then carry on: 252 / 902

Moving on to step 7:
902 can be fit into 252 0 times, resulting in a remainder of 252.
Use 0 as the next digit of our solution. 
Result so far: 5670.0
Deduct 0 from 252 and we're left with 252.
Bring next digit (9) of the dividend behind the 252 and repeat the process: 2529 / 902

On to step 8:
2529 divided by 902 is 2 with a remainder of 725.
Record the quotient 2 as the next digit in the result. 
Result so far: 56702.0
Subtract 1804 from 2529 to get 725.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7250, and continue the process.

On to step 9:
7250 divided by 902 is 8 with a remainder of 34.
The next digit of our result is 8. 
Result so far: 56702.8
Subtracting 7216 from 7250 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 10:
902 goes into 340 0 times with a remainder of 340.
Use 0 as the next digit of our solution. 
Result so far: 56702.8
If we take 0 away from 340, we end up with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Step 11:
902 can be fit into 3400 3 times, resulting in a remainder of 694.
Record the quotient 3 as the next digit in the result. 
Result so far: 56702.803
If we take 2706 away from 3400, we end up with 694.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6940, and continue the process.

Moving on to step 12:
902 can be fit into 6940 7 times, resulting in a remainder of 626.
Use 7 as the next digit of our solution. 
Result so far: 56702.8037
Subtract 6314 from 6940 to get 626.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

Advancing to step 13:
902 goes into 6260 6 times with a remainder of 848.
Put 6 as the next digit of the answer. 
Result so far: 56702.80376
If we take 5412 away from 6260, we end up with 848.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8480, and continue the process.

Let's proceed to step 14:
902 can be fit into 8480 9 times, resulting in a remainder of 362.
The number 9 becomes the next digit in our result. 
Result so far: 56702.803769
Deduct 8118 from 8480 and we're left with 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

On to step 15:
902 can be fit into 3620 4 times, resulting in a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 56702.8037694
Deduct 3608 from 3620 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 16:
120 divided by 902 is 0 with a remainder of 120.
Use 0 as the next digit of our solution. 
Result so far: 56702.8037694
The remainder is 120 after subtracting 0 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

The final result is 56702.8037694 with a remainder of 1.2e-07.
