We divide 33899570 by 840
The aim is to understand the frequency of 840 in 33899570.

Advancing to step 1:
3 divided by 840 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 840

Advancing to step 2:
840 goes into 33 0 times with a remainder of 33.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 33 leaves us with 33.
Grab the next digit (8) from the dividend, add it to 33, then carry on: 338 / 840

Moving on to step 3:
840 goes into 338 0 times with a remainder of 338.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 338 to get 338.
Fetch the next digit (9) from the dividend, attach it to 338 and continue: 3389 / 840

On to step 4:
840 goes into 3389 4 times with a remainder of 29.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 3360 away from 3389, we end up with 29.
Fetch the next digit (9) from the dividend, attach it to 29 and continue: 299 / 840

Moving on to step 5:
When dividing 299 by 840, we get 0 with a remainder of 299.
Put 0 as the next digit of the answer. 
Result so far: 40.0
If we take 0 away from 299, we end up with 299.
Take the next digit (5) from the dividend and append it to 299, then repeat: 2995 / 840

Going ahead to step 6:
840 can be fit into 2995 3 times, resulting in a remainder of 475.
The next digit of our result is 3. 
Result so far: 403.0
Deduct 2520 from 2995 and we're left with 475.
Take the next digit (7) from the dividend and append it to 475, then repeat: 4757 / 840

Going ahead to step 7:
840 can be fit into 4757 5 times, resulting in a remainder of 557.
Write down 5 as next digit of the result. 
Result so far: 4035.0
The remainder is 557 after subtracting 4200 from 4757.
Take the next digit (0) from the dividend and append it to 557, then repeat: 5570 / 840

Moving on to step 8:
840 can be fit into 5570 6 times, resulting in a remainder of 530.
Use 6 as the next digit of our solution. 
Result so far: 40356.0
If we subtract 5040 from 5570, we get 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Advancing to step 9:
5300 divided by 840 is 6 with a remainder of 260.
Put 6 as the next digit of the answer. 
Result so far: 40356.6
If we take 5040 away from 5300, 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.

Going ahead to step 10:
2600 divided by 840 is 3 with a remainder of 80.
Record the quotient 3 as the next digit in the result. 
Result so far: 40356.63
Subtracting 2520 from 2600 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.

Let's proceed to step 11:
800 divided by 840 is 0 with a remainder of 800.
Use 0 as the next digit of our solution. 
Result so far: 40356.63
If we take 0 away from 800, we end up with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Going ahead to step 12:
840 can be fit into 8000 9 times, resulting in a remainder of 440.
Use 9 as the next digit of our solution. 
Result so far: 40356.6309
Subtract 7560 from 8000 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Let's proceed to step 13:
When dividing 4400 by 840, we get 5 with a remainder of 200.
The next digit of our result is 5. 
Result so far: 40356.63095
Subtracting 4200 from 4400 leaves us 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 can be fit into 2000 2 times, resulting in a remainder of 320.
Put 2 as the next digit of the answer. 
Result so far: 40356.630952
Subtracting 1680 from 2000 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 15:
840 goes into 3200 3 times with a remainder of 680.
The number 3 becomes the next digit in our result. 
Result so far: 40356.6309523
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.

Going ahead to step 16:
If we divide 6800 by 840, we get 8 and a remainder of 80.
The number 8 becomes the next digit in our result. 
Result so far: 40356.63095238
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 quotient of the division is 40356.63095238, and the remainder is 8e-08.
