We're dividing 74761645 by 840 
The aim is to understand the frequency of 840 in 74761645.

Going ahead to step 1:
The number 840 fits into 7 0 times, leaving 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 (4) from the dividend to 7 and continue with: 74 / 840

Advancing to step 2:
The number 840 fits into 74 0 times, leaving a remainder of 74.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 74, we get 74.
Append the next digit (7) from the dividend to 74 and continue with: 747 / 840

On to step 3:
The number 840 fits into 747 0 times, leaving a remainder of 747.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 747, we get 747.
Fetch the next digit (6) from the dividend, attach it to 747 and continue: 7476 / 840

Advancing to step 4:
The number 840 fits into 7476 8 times, leaving a remainder of 756.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we take 6720 away from 7476, we end up with 756.
Include the next digit (1) from the dividend after 756, then repeat: 7561 / 840

Advancing to step 5:
7561 divided by 840 is 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 89.0
If we subtract 7560 from 7561, we get 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 840

Advancing to step 6:
840 goes into 16 0 times with a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 890.0
The remainder is 16 after subtracting 0 from 16.
Fetch the next digit (4) from the dividend, attach it to 16 and continue: 164 / 840

Going ahead to step 7:
The number 840 fits into 164 0 times, leaving a remainder of 164.
Write down 0 as next digit of the result. 
Result so far: 8900.0
Subtracting 0 from 164 leaves us with 164.
Take the next digit (5) from the dividend and append it to 164, then repeat: 1645 / 840

Advancing to step 8:
If we divide 1645 by 840, we get 1 and a remainder of 805.
Record the quotient 1 as the next digit in the result. 
Result so far: 89001.0
Subtracting 840 from 1645 leaves us with 805.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8050, and continue the process.

Going ahead to step 9:
840 goes into 8050 9 times with a remainder of 490.
Write down 9 as next digit of the result. 
Result so far: 89001.9
Deduct 7560 from 8050 and we're left with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Step 10:
If we divide 4900 by 840, we get 5 and a remainder of 700.
The number 5 becomes the next digit in our result. 
Result so far: 89001.95
Subtracting 4200 from 4900 leaves us with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Moving on to step 11:
840 goes into 7000 8 times with a remainder of 280.
Use 8 as the next digit of our solution. 
Result so far: 89001.958
Deduct 6720 from 7000 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Moving on to step 12:
2800 divided by 840 is 3 with a remainder of 280.
The number 3 becomes the next digit in our result. 
Result so far: 89001.9583
Deduct 2520 from 2800 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 13:
If we divide 2800 by 840, we get 3 and a remainder of 280.
Write down 3 as next digit of the result. 
Result so far: 89001.95833
If we subtract 2520 from 2800, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

The quotient of the division is 89001.95833, and the remainder is 0.00028.
