We look at the division of 51437389 by 941 
The aim is to understand the frequency of 941 in 51437389.

Let's proceed to step 1:
941 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 941

Advancing to step 2:
941 can be fit into 51 0 times, resulting in a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Include the next digit (4) from the dividend after 51, then repeat: 514 / 941

Moving on to step 3:
When dividing 514 by 941, we get 0 with a remainder of 514.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 514, we end up with 514.
Take the next digit (3) from the dividend and append it to 514, then repeat: 5143 / 941

Step 4:
If we divide 5143 by 941, we get 5 and a remainder of 438.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 4705 from 5143 and we're left with 438.
Take the next digit (7) from the dividend and append it to 438, then repeat: 4387 / 941

On to step 5:
941 goes into 4387 4 times with a remainder of 623.
The next digit of our result is 4. 
Result so far: 54.0
Deduct 3764 from 4387 and we're left with 623.
Bring next digit (3) of the dividend behind the 623 and repeat the process: 6233 / 941

Going ahead to step 6:
6233 divided by 941 is 6 with a remainder of 587.
The next digit of our result is 6. 
Result so far: 546.0
Deduct 5646 from 6233 and we're left with 587.
Take the next digit (8) from the dividend and append it to 587, then repeat: 5878 / 941

Advancing to step 7:
941 goes into 5878 6 times with a remainder of 232.
Put 6 as the next digit of the answer. 
Result so far: 5466.0
If we subtract 5646 from 5878, we get 232.
Grab the next digit (9) from the dividend, add it to 232, then carry on: 2329 / 941

Advancing to step 8:
941 can be fit into 2329 2 times, resulting in a remainder of 447.
Use 2 as the next digit of our solution. 
Result so far: 54662.0
If we subtract 1882 from 2329, we get 447.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4470, and continue the process.

On to step 9:
941 goes into 4470 4 times with a remainder of 706.
The number 4 becomes the next digit in our result. 
Result so far: 54662.4
Subtract 3764 from 4470 to get 706.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7060, and continue the process.

On to step 10:
If we divide 7060 by 941, we get 7 and a remainder of 473.
Use 7 as the next digit of our solution. 
Result so far: 54662.47
Subtracting 6587 from 7060 leaves us with 473.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4730, and continue the process.

On to step 11:
4730 divided by 941 is 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 54662.475
Subtracting 4705 from 4730 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 12:
941 can be fit into 250 0 times, resulting in a remainder of 250.
Record the quotient 0 as the next digit in the result. 
Result so far: 54662.475
The remainder is 250 after subtracting 0 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Going ahead to step 13:
941 can be fit into 2500 2 times, resulting in a remainder of 618.
Write down 2 as next digit of the result. 
Result so far: 54662.47502
Subtracting 1882 from 2500 leaves us with 618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6180, and continue the process.

Let's proceed to step 14:
If we divide 6180 by 941, we get 6 and a remainder of 534.
Put 6 as the next digit of the answer. 
Result so far: 54662.475026
Deduct 5646 from 6180 and we're left with 534.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

Going ahead to step 15:
If we divide 5340 by 941, we get 5 and a remainder of 635.
Record the quotient 5 as the next digit in the result. 
Result so far: 54662.4750265
If we subtract 4705 from 5340, we get 635.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6350, and continue the process.

Let's proceed to step 16:
The number 941 fits into 6350 6 times, leaving a remainder of 704.
The number 6 becomes the next digit in our result. 
Result so far: 54662.47502656
Subtracting 5646 from 6350 leaves us with 704.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

The final outcome is 54662.47502656, with a leftover of 7.04e-07.
