61691096 divided by 840 
The aim is to understand the frequency of 840 in 61691096.

Let's proceed to step 1:
840 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 840

Step 2:
61 divided by 840 is 0 with a remainder of 61.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 61 leaves us with 61.
Fetch the next digit (6) from the dividend, attach it to 61 and continue: 616 / 840

Step 3:
616 divided by 840 is 0 with a remainder of 616.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 616 to get 616.
Take the next digit (9) from the dividend and append it to 616, then repeat: 6169 / 840

Step 4:
The number 840 fits into 6169 7 times, leaving a remainder of 289.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 5880 from 6169 and we're left with 289.
Append the next digit (1) from the dividend to 289 and continue with: 2891 / 840

Advancing to step 5:
840 goes into 2891 3 times with a remainder of 371.
The number 3 becomes the next digit in our result. 
Result so far: 73.0
If we subtract 2520 from 2891, we get 371.
Take the next digit (0) from the dividend and append it to 371, then repeat: 3710 / 840

Let's proceed to step 6:
840 can be fit into 3710 4 times, resulting in a remainder of 350.
Write down 4 as next digit of the result. 
Result so far: 734.0
The remainder is 350 after subtracting 3360 from 3710.
Include the next digit (9) from the dividend after 350, then repeat: 3509 / 840

Going ahead to step 7:
If we divide 3509 by 840, we get 4 and a remainder of 149.
Put 4 as the next digit of the answer. 
Result so far: 7344.0
Subtract 3360 from 3509 to get 149.
Bring next digit (6) of the dividend behind the 149 and repeat the process: 1496 / 840

Moving on to step 8:
840 can be fit into 1496 1 times, resulting in a remainder of 656.
Record the quotient 1 as the next digit in the result. 
Result so far: 73441.0
If we subtract 840 from 1496, we get 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Moving on to step 9:
If we divide 6560 by 840, we get 7 and a remainder of 680.
Use 7 as the next digit of our solution. 
Result so far: 73441.7
Deduct 5880 from 6560 and we're left with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Step 10:
840 can be fit into 6800 8 times, resulting in a remainder of 80.
Write down 8 as next digit of the result. 
Result so far: 73441.78
If we take 6720 away from 6800, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 11:
The number 840 fits into 800 0 times, leaving a remainder of 800.
Record the quotient 0 as the next digit in the result. 
Result so far: 73441.78
Subtract 0 from 800 to get 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

On to step 12:
The number 840 fits into 8000 9 times, leaving a remainder of 440.
The next digit of our result is 9. 
Result so far: 73441.7809
The remainder is 440 after subtracting 7560 from 8000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Going ahead to step 13:
840 can be fit into 4400 5 times, resulting in a remainder of 200.
Record the quotient 5 as the next digit in the result. 
Result so far: 73441.78095
Deduct 4200 from 4400 and we're left 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.

Advancing to step 14:
840 goes into 2000 2 times with a remainder of 320.
The next digit of our result is 2. 
Result so far: 73441.780952
The remainder is 320 after subtracting 1680 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 15:
The number 840 fits into 3200 3 times, leaving a remainder of 680.
Record the quotient 3 as the next digit in the result. 
Result so far: 73441.7809523
The remainder is 680 after subtracting 2520 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Let's proceed to step 16:
6800 divided by 840 is 8 with a remainder of 80.
Use 8 as the next digit of our solution. 
Result so far: 73441.78095238
Subtracting 6720 from 6800 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final result is 73441.78095238 with a remainder of 8e-08.
