74723048 ÷ 591 
The aim is to understand the frequency of 591 in 74723048.

Let's proceed to step 1:
7 divided by 591 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 591

On to step 2:
If we divide 74 by 591, we get 0 and a remainder of 74.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 74 leaves us with 74.
Fetch the next digit (7) from the dividend, attach it to 74 and continue: 747 / 591

Advancing to step 3:
591 goes into 747 1 times with a remainder of 156.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 591 from 747 and we're left with 156.
Grab the next digit (2) from the dividend, add it to 156, then carry on: 1562 / 591

Step 4:
If we divide 1562 by 591, we get 2 and a remainder of 380.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Deduct 1182 from 1562 and we're left with 380.
Fetch the next digit (3) from the dividend, attach it to 380 and continue: 3803 / 591

Moving on to step 5:
3803 divided by 591 is 6 with a remainder of 257.
The number 6 becomes the next digit in our result. 
Result so far: 126.0
If we subtract 3546 from 3803, we get 257.
Include the next digit (0) from the dividend after 257, then repeat: 2570 / 591

Going ahead to step 6:
591 goes into 2570 4 times with a remainder of 206.
Write down 4 as next digit of the result. 
Result so far: 1264.0
The remainder is 206 after subtracting 2364 from 2570.
Take the next digit (4) from the dividend and append it to 206, then repeat: 2064 / 591

Advancing to step 7:
591 can be fit into 2064 3 times, resulting in a remainder of 291.
Record the quotient 3 as the next digit in the result. 
Result so far: 12643.0
Subtract 1773 from 2064 to get 291.
Bring next digit (8) of the dividend behind the 291 and repeat the process: 2918 / 591

Step 8:
591 goes into 2918 4 times with a remainder of 554.
The number 4 becomes the next digit in our result. 
Result so far: 126434.0
If we subtract 2364 from 2918, we get 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

On to step 9:
5540 divided by 591 is 9 with a remainder of 221.
Write down 9 as next digit of the result. 
Result so far: 126434.9
Subtract 5319 from 5540 to get 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Step 10:
591 can be fit into 2210 3 times, resulting in a remainder of 437.
Record the quotient 3 as the next digit in the result. 
Result so far: 126434.93
Deduct 1773 from 2210 and we're left with 437.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4370, and continue the process.

Moving on to step 11:
4370 divided by 591 is 7 with a remainder of 233.
Record the quotient 7 as the next digit in the result. 
Result so far: 126434.937
Subtract 4137 from 4370 to get 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Advancing to step 12:
The number 591 fits into 2330 3 times, leaving a remainder of 557.
Record the quotient 3 as the next digit in the result. 
Result so far: 126434.9373
Deduct 1773 from 2330 and we're left with 557.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5570, and continue the process.

Going ahead to step 13:
591 goes into 5570 9 times with a remainder of 251.
The next digit of our result is 9. 
Result so far: 126434.93739
If we take 5319 away from 5570, we end up with 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Step 14:
If we divide 2510 by 591, we get 4 and a remainder of 146.
Use 4 as the next digit of our solution. 
Result so far: 126434.937394
If we take 2364 away from 2510, we end up with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

On to step 15:
591 can be fit into 1460 2 times, resulting in a remainder of 278.
Put 2 as the next digit of the answer. 
Result so far: 126434.9373942
Deduct 1182 from 1460 and we're left with 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Step 16:
591 goes into 2780 4 times with a remainder of 416.
The number 4 becomes the next digit in our result. 
Result so far: 126434.93739424
Subtract 2364 from 2780 to get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

The final result is 126434.93739424 with a remainder of 4.16e-07.
