We divide 77815689 by 670
The aim is to understand the frequency of 670 in 77815689.

Moving on to step 1:
7 divided by 670 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 670

On to step 2:
77 divided by 670 is 0 with a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Include the next digit (8) from the dividend after 77, then repeat: 778 / 670

Let's proceed to step 3:
The number 670 fits into 778 1 times, leaving a remainder of 108.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 670 from 778 to get 108.
Include the next digit (1) from the dividend after 108, then repeat: 1081 / 670

Step 4:
If we divide 1081 by 670, we get 1 and a remainder of 411.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Deduct 670 from 1081 and we're left with 411.
Bring next digit (5) of the dividend behind the 411 and repeat the process: 4115 / 670

Going ahead to step 5:
670 goes into 4115 6 times with a remainder of 95.
Put 6 as the next digit of the answer. 
Result so far: 116.0
Deduct 4020 from 4115 and we're left with 95.
Bring next digit (6) of the dividend behind the 95 and repeat the process: 956 / 670

Step 6:
The number 670 fits into 956 1 times, leaving a remainder of 286.
The number 1 becomes the next digit in our result. 
Result so far: 1161.0
If we subtract 670 from 956, we get 286.
Grab the next digit (8) from the dividend, add it to 286, then carry on: 2868 / 670

Let's proceed to step 7:
The number 670 fits into 2868 4 times, leaving a remainder of 188.
The next digit of our result is 4. 
Result so far: 11614.0
Deduct 2680 from 2868 and we're left with 188.
Take the next digit (9) from the dividend and append it to 188, then repeat: 1889 / 670

Going ahead to step 8:
If we divide 1889 by 670, we get 2 and a remainder of 549.
Use 2 as the next digit of our solution. 
Result so far: 116142.0
Subtracting 1340 from 1889 leaves us 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:
When dividing 5490 by 670, we get 8 with a remainder of 130.
Put 8 as the next digit of the answer. 
Result so far: 116142.8
If we subtract 5360 from 5490, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 10:
If we divide 1300 by 670, we get 1 and a remainder of 630.
Record the quotient 1 as the next digit in the result. 
Result so far: 116142.81
The remainder is 630 after subtracting 670 from 1300.
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 11:
When dividing 6300 by 670, we get 9 with a remainder of 270.
Put 9 as the next digit of the answer. 
Result so far: 116142.819
If we take 6030 away from 6300, we end up with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

On to step 12:
670 can be fit into 2700 4 times, resulting in a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 116142.8194
If we take 2680 away from 2700, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 13:
When dividing 200 by 670, we get 0 with a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 116142.8194
If we take 0 away from 200, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 14:
2000 divided by 670 is 2 with a remainder of 660.
Record the quotient 2 as the next digit in the result. 
Result so far: 116142.819402
If we subtract 1340 from 2000, we get 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Going ahead to step 15:
670 can be fit into 6600 9 times, resulting in a remainder of 570.
Record the quotient 9 as the next digit in the result. 
Result so far: 116142.8194029
Subtract 6030 from 6600 to get 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Going ahead to step 16:
670 goes into 5700 8 times with a remainder of 340.
Put 8 as the next digit of the answer. 
Result so far: 116142.81940298
If we subtract 5360 from 5700, we get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

The final result is 116142.81940298 with a remainder of 3.4e-07.
