42154642 ÷ 430 
We want to divide 42154642 by 430.

Step 1:
430 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 430

On to step 2:
430 can be fit into 42 0 times, resulting in a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Append the next digit (1) from the dividend to 42 and continue with: 421 / 430

Let's proceed to step 3:
430 goes into 421 0 times with a remainder of 421.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 421, we end up with 421.
Take the next digit (5) from the dividend and append it to 421, then repeat: 4215 / 430

Advancing to step 4:
430 can be fit into 4215 9 times, resulting in a remainder of 345.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 3870 from 4215 to get 345.
Append the next digit (4) from the dividend to 345 and continue with: 3454 / 430

Going ahead to step 5:
When dividing 3454 by 430, we get 8 with a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 98.0
If we subtract 3440 from 3454, we get 14.
Grab the next digit (6) from the dividend, add it to 14, then carry on: 146 / 430

Advancing to step 6:
If we divide 146 by 430, we get 0 and a remainder of 146.
The number 0 becomes the next digit in our result. 
Result so far: 980.0
If we subtract 0 from 146, we get 146.
Include the next digit (4) from the dividend after 146, then repeat: 1464 / 430

On to step 7:
430 can be fit into 1464 3 times, resulting in a remainder of 174.
Use 3 as the next digit of our solution. 
Result so far: 9803.0
Subtract 1290 from 1464 to get 174.
Bring next digit (2) of the dividend behind the 174 and repeat the process: 1742 / 430

Step 8:
If we divide 1742 by 430, we get 4 and a remainder of 22.
The number 4 becomes the next digit in our result. 
Result so far: 98034.0
Subtract 1720 from 1742 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 9:
If we divide 220 by 430, we get 0 and a remainder of 220.
Use 0 as the next digit of our solution. 
Result so far: 98034.0
Deduct 0 from 220 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Advancing to step 10:
When dividing 2200 by 430, we get 5 with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 98034.05
The remainder is 50 after subtracting 2150 from 2200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 11:
430 goes into 500 1 times with a remainder of 70.
The number 1 becomes the next digit in our result. 
Result so far: 98034.051
If we subtract 430 from 500, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 12:
430 can be fit into 700 1 times, resulting in a remainder of 270.
Put 1 as the next digit of the answer. 
Result so far: 98034.0511
If we take 430 away from 700, we end up with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

The final outcome is 98034.0511, with a leftover of 0.0027.
