The aim is to understand the frequency of 420 in 29503445.

Step 1:
The number 420 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 420

On to step 2:
420 can be fit into 29 0 times, resulting in a remainder of 29.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 29 and we're left with 29.
Grab the next digit (5) from the dividend, add it to 29, then carry on: 295 / 420

Step 3:
420 goes into 295 0 times with a remainder of 295.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 295 to get 295.
Append the next digit (0) from the dividend to 295 and continue with: 2950 / 420

On to step 4:
420 can be fit into 2950 7 times, resulting in a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we take 2940 away from 2950, we end up with 10.
Bring next digit (3) of the dividend behind the 10 and repeat the process: 103 / 420

Going ahead to step 5:
The number 420 fits into 103 0 times, leaving a remainder of 103.
The next digit of our result is 0. 
Result so far: 70.0
If we take 0 away from 103, we end up with 103.
Fetch the next digit (4) from the dividend, attach it to 103 and continue: 1034 / 420

Going ahead to step 6:
1034 divided by 420 is 2 with a remainder of 194.
Use 2 as the next digit of our solution. 
Result so far: 702.0
Subtract 840 from 1034 to get 194.
Bring next digit (4) of the dividend behind the 194 and repeat the process: 1944 / 420

Advancing to step 7:
If we divide 1944 by 420, we get 4 and a remainder of 264.
The number 4 becomes the next digit in our result. 
Result so far: 7024.0
The remainder is 264 after subtracting 1680 from 1944.
Bring next digit (5) of the dividend behind the 264 and repeat the process: 2645 / 420

Going ahead to step 8:
2645 divided by 420 is 6 with a remainder of 125.
Write down 6 as next digit of the result. 
Result so far: 70246.0
If we take 2520 away from 2645, we end up with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Going ahead to step 9:
420 goes into 1250 2 times with a remainder of 410.
Use 2 as the next digit of our solution. 
Result so far: 70246.2
If we take 840 away from 1250, we end up with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Advancing to step 10:
4100 divided by 420 is 9 with a remainder of 320.
The number 9 becomes the next digit in our result. 
Result so far: 70246.29
Subtracting 3780 from 4100 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.

Advancing to step 11:
When dividing 3200 by 420, we get 7 with a remainder of 260.
Put 7 as the next digit of the answer. 
Result so far: 70246.297
Subtracting 2940 from 3200 leaves us 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.

Step 12:
2600 divided by 420 is 6 with a remainder of 80.
Put 6 as the next digit of the answer. 
Result so far: 70246.2976
Deduct 2520 from 2600 and we're left 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.

On to step 13:
800 divided by 420 is 1 with a remainder of 380.
Use 1 as the next digit of our solution. 
Result so far: 70246.29761
If we subtract 420 from 800, we get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

On to step 14:
3800 divided by 420 is 9 with a remainder of 20.
Record the quotient 9 as the next digit in the result. 
Result so far: 70246.297619
If we subtract 3780 from 3800, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 15:
When dividing 200 by 420, we get 0 with a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 70246.297619
The remainder is 200 after subtracting 0 from 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 16:
2000 divided by 420 is 4 with a remainder of 320.
Put 4 as the next digit of the answer. 
Result so far: 70246.29761904
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.

Our division results in 70246.29761904 with a remaining 3.2e-07.
