51581964 ÷ 706 
The aim is to understand the frequency of 706 in 51581964.

Moving on to step 1:
The number 706 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 706

Going ahead to step 2:
51 divided by 706 is 0 with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Take the next digit (5) from the dividend and append it to 51, then repeat: 515 / 706

Let's proceed to step 3:
706 goes into 515 0 times with a remainder of 515.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 515 after subtracting 0 from 515.
Append the next digit (8) from the dividend to 515 and continue with: 5158 / 706

Let's proceed to step 4:
706 can be fit into 5158 7 times, resulting in a remainder of 216.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 216 after subtracting 4942 from 5158.
Take the next digit (1) from the dividend and append it to 216, then repeat: 2161 / 706

Advancing to step 5:
When dividing 2161 by 706, we get 3 with a remainder of 43.
Write down 3 as next digit of the result. 
Result so far: 73.0
If we subtract 2118 from 2161, we get 43.
Append the next digit (9) from the dividend to 43 and continue with: 439 / 706

Moving on to step 6:
706 goes into 439 0 times with a remainder of 439.
Write down 0 as next digit of the result. 
Result so far: 730.0
The remainder is 439 after subtracting 0 from 439.
Take the next digit (6) from the dividend and append it to 439, then repeat: 4396 / 706

Going ahead to step 7:
The number 706 fits into 4396 6 times, leaving a remainder of 160.
Use 6 as the next digit of our solution. 
Result so far: 7306.0
Subtract 4236 from 4396 to get 160.
Grab the next digit (4) from the dividend, add it to 160, then carry on: 1604 / 706

Advancing to step 8:
If we divide 1604 by 706, we get 2 and a remainder of 192.
Put 2 as the next digit of the answer. 
Result so far: 73062.0
Deduct 1412 from 1604 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

On to step 9:
706 can be fit into 1920 2 times, resulting in a remainder of 508.
Put 2 as the next digit of the answer. 
Result so far: 73062.2
If we take 1412 away from 1920, we end up with 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

On to step 10:
When dividing 5080 by 706, we get 7 with a remainder of 138.
The next digit of our result is 7. 
Result so far: 73062.27
Deduct 4942 from 5080 and we're left with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Moving on to step 11:
706 goes into 1380 1 times with a remainder of 674.
Put 1 as the next digit of the answer. 
Result so far: 73062.271
Subtract 706 from 1380 to get 674.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6740, and continue the process.

Moving on to step 12:
When dividing 6740 by 706, we get 9 with a remainder of 386.
The next digit of our result is 9. 
Result so far: 73062.2719
The remainder is 386 after subtracting 6354 from 6740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Let's proceed to step 13:
706 goes into 3860 5 times with a remainder of 330.
Record the quotient 5 as the next digit in the result. 
Result so far: 73062.27195
If we subtract 3530 from 3860, we get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Step 14:
When dividing 3300 by 706, we get 4 with a remainder of 476.
Put 4 as the next digit of the answer. 
Result so far: 73062.271954
If we subtract 2824 from 3300, we get 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Going ahead to step 15:
When dividing 4760 by 706, we get 6 with a remainder of 524.
The next digit of our result is 6. 
Result so far: 73062.2719546
The remainder is 524 after subtracting 4236 from 4760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Advancing to step 16:
If we divide 5240 by 706, we get 7 and a remainder of 298.
Put 7 as the next digit of the answer. 
Result so far: 73062.27195467
Subtracting 4942 from 5240 leaves us with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

The final result is 73062.27195467 with a remainder of 2.98e-07.
