We divide 53671585 by 397
The aim is to understand the frequency of 397 in 53671585.

Advancing to step 1:
When dividing 5 by 397, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 397

Moving on to step 2:
The number 397 fits into 53 0 times, leaving a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 53, we end up with 53.
Append the next digit (6) from the dividend to 53 and continue with: 536 / 397

Going ahead to step 3:
When dividing 536 by 397, we get 1 with a remainder of 139.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 397 from 536 and we're left with 139.
Fetch the next digit (7) from the dividend, attach it to 139 and continue: 1397 / 397

Advancing to step 4:
The number 397 fits into 1397 3 times, leaving a remainder of 206.
The next digit of our result is 3. 
Result so far: 13.0
If we take 1191 away from 1397, we end up with 206.
Include the next digit (1) from the dividend after 206, then repeat: 2061 / 397

Let's proceed to step 5:
If we divide 2061 by 397, we get 5 and a remainder of 76.
Use 5 as the next digit of our solution. 
Result so far: 135.0
Subtracting 1985 from 2061 leaves us with 76.
Append the next digit (5) from the dividend to 76 and continue with: 765 / 397

Advancing to step 6:
When dividing 765 by 397, we get 1 with a remainder of 368.
Write down 1 as next digit of the result. 
Result so far: 1351.0
Subtract 397 from 765 to get 368.
Fetch the next digit (8) from the dividend, attach it to 368 and continue: 3688 / 397

Let's proceed to step 7:
3688 divided by 397 is 9 with a remainder of 115.
Put 9 as the next digit of the answer. 
Result so far: 13519.0
The remainder is 115 after subtracting 3573 from 3688.
Grab the next digit (5) from the dividend, add it to 115, then carry on: 1155 / 397

Advancing to step 8:
1155 divided by 397 is 2 with a remainder of 361.
Write down 2 as next digit of the result. 
Result so far: 135192.0
Subtract 794 from 1155 to get 361.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

Step 9:
397 goes into 3610 9 times with a remainder of 37.
The next digit of our result is 9. 
Result so far: 135192.9
Subtracting 3573 from 3610 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 10:
370 divided by 397 is 0 with a remainder of 370.
Put 0 as the next digit of the answer. 
Result so far: 135192.9
If we take 0 away from 370, we end up with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Step 11:
397 can be fit into 3700 9 times, resulting in a remainder of 127.
Record the quotient 9 as the next digit in the result. 
Result so far: 135192.909
Subtract 3573 from 3700 to get 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Going ahead to step 12:
1270 divided by 397 is 3 with a remainder of 79.
The next digit of our result is 3. 
Result so far: 135192.9093
If we take 1191 away from 1270, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

On to step 13:
When dividing 790 by 397, we get 1 with a remainder of 393.
Use 1 as the next digit of our solution. 
Result so far: 135192.90931
Deduct 397 from 790 and we're left with 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

Moving on to step 14:
The number 397 fits into 3930 9 times, leaving a remainder of 357.
Use 9 as the next digit of our solution. 
Result so far: 135192.909319
Deduct 3573 from 3930 and we're left with 357.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

Step 15:
397 can be fit into 3570 8 times, resulting in a remainder of 394.
The next digit of our result is 8. 
Result so far: 135192.9093198
The remainder is 394 after subtracting 3176 from 3570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Moving on to step 16:
If we divide 3940 by 397, we get 9 and a remainder of 367.
Use 9 as the next digit of our solution. 
Result so far: 135192.90931989
If we subtract 3573 from 3940, we get 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

The quotient of the division is 135192.90931989, and the remainder is 3.67e-07.
