53420329 divided by 837 
The aim is to understand the frequency of 837 in 53420329.

Let's proceed to step 1:
837 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 837

Advancing to step 2:
When dividing 53 by 837, we get 0 with a remainder of 53.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 53, we end up with 53.
Take the next digit (4) from the dividend and append it to 53, then repeat: 534 / 837

Advancing to step 3:
If we divide 534 by 837, we get 0 and a remainder of 534.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 534 to get 534.
Take the next digit (2) from the dividend and append it to 534, then repeat: 5342 / 837

On to step 4:
837 goes into 5342 6 times with a remainder of 320.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 320 after subtracting 5022 from 5342.
Bring next digit (0) of the dividend behind the 320 and repeat the process: 3200 / 837

Step 5:
When dividing 3200 by 837, we get 3 with a remainder of 689.
The next digit of our result is 3. 
Result so far: 63.0
The remainder is 689 after subtracting 2511 from 3200.
Bring next digit (3) of the dividend behind the 689 and repeat the process: 6893 / 837

Advancing to step 6:
837 can be fit into 6893 8 times, resulting in a remainder of 197.
The next digit of our result is 8. 
Result so far: 638.0
Deduct 6696 from 6893 and we're left with 197.
Bring next digit (2) of the dividend behind the 197 and repeat the process: 1972 / 837

Step 7:
1972 divided by 837 is 2 with a remainder of 298.
The number 2 becomes the next digit in our result. 
Result so far: 6382.0
The remainder is 298 after subtracting 1674 from 1972.
Append the next digit (9) from the dividend to 298 and continue with: 2989 / 837

Step 8:
When dividing 2989 by 837, we get 3 with a remainder of 478.
Record the quotient 3 as the next digit in the result. 
Result so far: 63823.0
If we subtract 2511 from 2989, we get 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Step 9:
The number 837 fits into 4780 5 times, leaving a remainder of 595.
The number 5 becomes the next digit in our result. 
Result so far: 63823.5
Subtract 4185 from 4780 to get 595.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5950, and continue the process.

On to step 10:
5950 divided by 837 is 7 with a remainder of 91.
The next digit of our result is 7. 
Result so far: 63823.57
If we take 5859 away from 5950, we end up with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Let's proceed to step 11:
910 divided by 837 is 1 with a remainder of 73.
Record the quotient 1 as the next digit in the result. 
Result so far: 63823.571
If we take 837 away from 910, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Going ahead to step 12:
If we divide 730 by 837, we get 0 and a remainder of 730.
Put 0 as the next digit of the answer. 
Result so far: 63823.571
Deduct 0 from 730 and we're left with 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

Going ahead to step 13:
7300 divided by 837 is 8 with a remainder of 604.
Put 8 as the next digit of the answer. 
Result so far: 63823.57108
The remainder is 604 after subtracting 6696 from 7300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Moving on to step 14:
6040 divided by 837 is 7 with a remainder of 181.
Use 7 as the next digit of our solution. 
Result so far: 63823.571087
Subtract 5859 from 6040 to get 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Let's proceed to step 15:
If we divide 1810 by 837, we get 2 and a remainder of 136.
The number 2 becomes the next digit in our result. 
Result so far: 63823.5710872
Subtracting 1674 from 1810 leaves us with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Step 16:
When dividing 1360 by 837, we get 1 with a remainder of 523.
Use 1 as the next digit of our solution. 
Result so far: 63823.57108721
If we take 837 away from 1360, we end up with 523.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5230, and continue the process.

After the division, we end up with 63823.57108721 and a remainder of 5.23e-07.
