70532387 ÷ 690 
The aim is to understand the frequency of 690 in 70532387.

Going ahead to step 1:
When dividing 7 by 690, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 690

Moving on to step 2:
690 goes into 70 0 times with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 70 after subtracting 0 from 70.
Fetch the next digit (5) from the dividend, attach it to 70 and continue: 705 / 690

Moving on to step 3:
The number 690 fits into 705 1 times, leaving a remainder of 15.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 690 from 705 and we're left with 15.
Grab the next digit (3) from the dividend, add it to 15, then carry on: 153 / 690

Moving on to step 4:
690 goes into 153 0 times with a remainder of 153.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 153, we get 153.
Append the next digit (2) from the dividend to 153 and continue with: 1532 / 690

Advancing to step 5:
690 goes into 1532 2 times with a remainder of 152.
Use 2 as the next digit of our solution. 
Result so far: 102.0
Subtracting 1380 from 1532 leaves us with 152.
Include the next digit (3) from the dividend after 152, then repeat: 1523 / 690

Step 6:
When dividing 1523 by 690, we get 2 with a remainder of 143.
Write down 2 as next digit of the result. 
Result so far: 1022.0
Subtract 1380 from 1523 to get 143.
Bring next digit (8) of the dividend behind the 143 and repeat the process: 1438 / 690

Step 7:
If we divide 1438 by 690, we get 2 and a remainder of 58.
Record the quotient 2 as the next digit in the result. 
Result so far: 10222.0
Subtracting 1380 from 1438 leaves us with 58.
Fetch the next digit (7) from the dividend, attach it to 58 and continue: 587 / 690

Going ahead to step 8:
690 can be fit into 587 0 times, resulting in a remainder of 587.
Record the quotient 0 as the next digit in the result. 
Result so far: 102220.0
If we take 0 away from 587, we end up with 587.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5870, and continue the process.

On to step 9:
If we divide 5870 by 690, we get 8 and a remainder of 350.
Put 8 as the next digit of the answer. 
Result so far: 102220.8
The remainder is 350 after subtracting 5520 from 5870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Going ahead to step 10:
690 can be fit into 3500 5 times, resulting in a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 102220.85
Subtracting 3450 from 3500 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 11:
690 goes into 500 0 times with a remainder of 500.
The next digit of our result is 0. 
Result so far: 102220.85
Subtracting 0 from 500 leaves us with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Going ahead to step 12:
When dividing 5000 by 690, we get 7 with a remainder of 170.
The number 7 becomes the next digit in our result. 
Result so far: 102220.8507
Deduct 4830 from 5000 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

On to step 13:
690 can be fit into 1700 2 times, resulting in a remainder of 320.
Record the quotient 2 as the next digit in the result. 
Result so far: 102220.85072
Subtract 1380 from 1700 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 14:
If we divide 3200 by 690, we get 4 and a remainder of 440.
The number 4 becomes the next digit in our result. 
Result so far: 102220.850724
Deduct 2760 from 3200 and we're left with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Advancing to step 15:
When dividing 4400 by 690, we get 6 with a remainder of 260.
Record the quotient 6 as the next digit in the result. 
Result so far: 102220.8507246
If we take 4140 away from 4400, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Moving on to step 16:
690 can be fit into 2600 3 times, resulting in a remainder of 530.
The next digit of our result is 3. 
Result so far: 102220.85072463
Deduct 2070 from 2600 and we're left with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Our division results in 102220.85072463 with a remaining 5.3e-07.
