71089020 ÷ 753 
The aim is to understand the frequency of 753 in 71089020.

Let's proceed to step 1:
The number 753 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 753

Step 2:
If we divide 71 by 753, we get 0 and a remainder of 71.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 71 to get 71.
Grab the next digit (0) from the dividend, add it to 71, then carry on: 710 / 753

Going ahead to step 3:
When dividing 710 by 753, we get 0 with a remainder of 710.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 710, we get 710.
Append the next digit (8) from the dividend to 710 and continue with: 7108 / 753

Step 4:
7108 divided by 753 is 9 with a remainder of 331.
The next digit of our result is 9. 
Result so far: 9.0
Subtracting 6777 from 7108 leaves us with 331.
Bring next digit (9) of the dividend behind the 331 and repeat the process: 3319 / 753

On to step 5:
3319 divided by 753 is 4 with a remainder of 307.
Write down 4 as next digit of the result. 
Result so far: 94.0
The remainder is 307 after subtracting 3012 from 3319.
Fetch the next digit (0) from the dividend, attach it to 307 and continue: 3070 / 753

Advancing to step 6:
If we divide 3070 by 753, we get 4 and a remainder of 58.
Record the quotient 4 as the next digit in the result. 
Result so far: 944.0
Subtract 3012 from 3070 to get 58.
Fetch the next digit (2) from the dividend, attach it to 58 and continue: 582 / 753

On to step 7:
753 can be fit into 582 0 times, resulting in a remainder of 582.
The next digit of our result is 0. 
Result so far: 9440.0
If we subtract 0 from 582, we get 582.
Fetch the next digit (0) from the dividend, attach it to 582 and continue: 5820 / 753

Going ahead to step 8:
753 can be fit into 5820 7 times, resulting in a remainder of 549.
Put 7 as the next digit of the answer. 
Result so far: 94407.0
If we take 5271 away from 5820, we end up with 549.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5490, and continue the process.

Let's proceed to step 9:
5490 divided by 753 is 7 with a remainder of 219.
Use 7 as the next digit of our solution. 
Result so far: 94407.7
If we subtract 5271 from 5490, we get 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

Moving on to step 10:
753 can be fit into 2190 2 times, resulting in a remainder of 684.
Put 2 as the next digit of the answer. 
Result so far: 94407.72
Deduct 1506 from 2190 and we're left with 684.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6840, and continue the process.

Going ahead to step 11:
The number 753 fits into 6840 9 times, leaving a remainder of 63.
The next digit of our result is 9. 
Result so far: 94407.729
Subtracting 6777 from 6840 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 12:
753 goes into 630 0 times with a remainder of 630.
Record the quotient 0 as the next digit in the result. 
Result so far: 94407.729
If we subtract 0 from 630, we get 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Advancing to step 13:
753 goes into 6300 8 times with a remainder of 276.
Use 8 as the next digit of our solution. 
Result so far: 94407.72908
The remainder is 276 after subtracting 6024 from 6300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Let's proceed to step 14:
753 can be fit into 2760 3 times, resulting in a remainder of 501.
Use 3 as the next digit of our solution. 
Result so far: 94407.729083
The remainder is 501 after subtracting 2259 from 2760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5010, and continue the process.

Advancing to step 15:
753 can be fit into 5010 6 times, resulting in a remainder of 492.
Use 6 as the next digit of our solution. 
Result so far: 94407.7290836
Subtracting 4518 from 5010 leaves us with 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

Let's proceed to step 16:
If we divide 4920 by 753, we get 6 and a remainder of 402.
Write down 6 as next digit of the result. 
Result so far: 94407.72908366
The remainder is 402 after subtracting 4518 from 4920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

The final result is 94407.72908366 with a remainder of 4.02e-07.
