Let's divide 51290340 by 857
The aim is to understand the frequency of 857 in 51290340.

Moving on to step 1:
5 divided by 857 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 857

Going ahead to step 2:
857 can be fit into 51 0 times, resulting in a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Fetch the next digit (2) from the dividend, attach it to 51 and continue: 512 / 857

Let's proceed to step 3:
857 can be fit into 512 0 times, resulting in a remainder of 512.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 512, we get 512.
Fetch the next digit (9) from the dividend, attach it to 512 and continue: 5129 / 857

Going ahead to step 4:
857 goes into 5129 5 times with a remainder of 844.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 4285 from 5129 and we're left with 844.
Bring next digit (0) of the dividend behind the 844 and repeat the process: 8440 / 857

Moving on to step 5:
When dividing 8440 by 857, we get 9 with a remainder of 727.
Record the quotient 9 as the next digit in the result. 
Result so far: 59.0
Subtract 7713 from 8440 to get 727.
Fetch the next digit (3) from the dividend, attach it to 727 and continue: 7273 / 857

Moving on to step 6:
857 can be fit into 7273 8 times, resulting in a remainder of 417.
Write down 8 as next digit of the result. 
Result so far: 598.0
The remainder is 417 after subtracting 6856 from 7273.
Grab the next digit (4) from the dividend, add it to 417, then carry on: 4174 / 857

Advancing to step 7:
When dividing 4174 by 857, we get 4 with a remainder of 746.
Write down 4 as next digit of the result. 
Result so far: 5984.0
The remainder is 746 after subtracting 3428 from 4174.
Grab the next digit (0) from the dividend, add it to 746, then carry on: 7460 / 857

Going ahead to step 8:
When dividing 7460 by 857, we get 8 with a remainder of 604.
Record the quotient 8 as the next digit in the result. 
Result so far: 59848.0
Deduct 6856 from 7460 and we're left with 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Going ahead to step 9:
6040 divided by 857 is 7 with a remainder of 41.
Put 7 as the next digit of the answer. 
Result so far: 59848.7
Subtracting 5999 from 6040 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 10:
When dividing 410 by 857, we get 0 with a remainder of 410.
Record the quotient 0 as the next digit in the result. 
Result so far: 59848.7
Subtracting 0 from 410 leaves us with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Advancing to step 11:
857 goes into 4100 4 times with a remainder of 672.
Record the quotient 4 as the next digit in the result. 
Result so far: 59848.704
If we take 3428 away from 4100, we end up with 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

Moving on to step 12:
If we divide 6720 by 857, we get 7 and a remainder of 721.
Use 7 as the next digit of our solution. 
Result so far: 59848.7047
Subtract 5999 from 6720 to get 721.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7210, and continue the process.

On to step 13:
857 goes into 7210 8 times with a remainder of 354.
Put 8 as the next digit of the answer. 
Result so far: 59848.70478
Subtracting 6856 from 7210 leaves us with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Let's proceed to step 14:
857 goes into 3540 4 times with a remainder of 112.
Record the quotient 4 as the next digit in the result. 
Result so far: 59848.704784
Subtracting 3428 from 3540 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Going ahead to step 15:
857 can be fit into 1120 1 times, resulting in a remainder of 263.
Use 1 as the next digit of our solution. 
Result so far: 59848.7047841
If we take 857 away from 1120, we end up with 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Step 16:
2630 divided by 857 is 3 with a remainder of 59.
Put 3 as the next digit of the answer. 
Result so far: 59848.70478413
Subtracting 2571 from 2630 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

After the division, we end up with 59848.70478413 and a remainder of 5.9e-08.
