We divide 45990073 by 84
The aim is to understand the frequency of 84 in 45990073.

Going ahead to step 1:
When dividing 4 by 84, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 84

On to step 2:
45 divided by 84 is 0 with a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Grab the next digit (9) from the dividend, add it to 45, then carry on: 459 / 84

Going ahead to step 3:
459 divided by 84 is 5 with a remainder of 39.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 39 after subtracting 420 from 459.
Grab the next digit (9) from the dividend, add it to 39, then carry on: 399 / 84

On to step 4:
84 goes into 399 4 times with a remainder of 63.
Record the quotient 4 as the next digit in the result. 
Result so far: 54.0
If we take 336 away from 399, we end up with 63.
Include the next digit (0) from the dividend after 63, then repeat: 630 / 84

On to step 5:
630 divided by 84 is 7 with a remainder of 42.
The number 7 becomes the next digit in our result. 
Result so far: 547.0
Deduct 588 from 630 and we're left with 42.
Append the next digit (0) from the dividend to 42 and continue with: 420 / 84

Step 6:
84 goes into 420 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 5475.0
If we subtract 420 from 420, we get 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 84

On to step 7:
84 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 54750.0
If we take 0 away from 7, we end up with 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 84

On to step 8:
73 divided by 84 is 0 with a remainder of 73.
Record the quotient 0 as the next digit in the result. 
Result so far: 547500.0
Subtract 0 from 73 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Advancing to step 9:
When dividing 730 by 84, we get 8 with a remainder of 58.
Put 8 as the next digit of the answer. 
Result so far: 547500.8
If we take 672 away from 730, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 10:
84 can be fit into 580 6 times, resulting in a remainder of 76.
The next digit of our result is 6. 
Result so far: 547500.86
The remainder is 76 after subtracting 504 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 11:
The number 84 fits into 760 9 times, leaving a remainder of 4.
The next digit of our result is 9. 
Result so far: 547500.869
Deduct 756 from 760 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 12:
84 goes into 40 0 times with a remainder of 40.
The next digit of our result is 0. 
Result so far: 547500.869
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 13:
400 divided by 84 is 4 with a remainder of 64.
Write down 4 as next digit of the result. 
Result so far: 547500.86904
Subtracting 336 from 400 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 14:
If we divide 640 by 84, we get 7 and a remainder of 52.
Write down 7 as next digit of the result. 
Result so far: 547500.869047
Subtract 588 from 640 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 15:
84 goes into 520 6 times with a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 547500.8690476
If we take 504 away from 520, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 16:
84 goes into 160 1 times with a remainder of 76.
Use 1 as the next digit of our solution. 
Result so far: 547500.86904761
Deduct 84 from 160 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The quotient of the division is 547500.86904761, and the remainder is 7.6e-08.
