18345170 ÷ 429 
We want to figure out the number of times 18345170 can be divided by 429.

Going ahead to step 1:
The number 429 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 429

Advancing to step 2:
When dividing 18 by 429, we get 0 with a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Take the next digit (3) from the dividend and append it to 18, then repeat: 183 / 429

Going ahead to step 3:
If we divide 183 by 429, we get 0 and a remainder of 183.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 183 after subtracting 0 from 183.
Append the next digit (4) from the dividend to 183 and continue with: 1834 / 429

Going ahead to step 4:
If we divide 1834 by 429, we get 4 and a remainder of 118.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 1716 from 1834 leaves us with 118.
Grab the next digit (5) from the dividend, add it to 118, then carry on: 1185 / 429

Let's proceed to step 5:
429 can be fit into 1185 2 times, resulting in a remainder of 327.
Use 2 as the next digit of our solution. 
Result so far: 42.0
If we subtract 858 from 1185, we get 327.
Grab the next digit (1) from the dividend, add it to 327, then carry on: 3271 / 429

Step 6:
When dividing 3271 by 429, we get 7 with a remainder of 268.
The next digit of our result is 7. 
Result so far: 427.0
Deduct 3003 from 3271 and we're left with 268.
Fetch the next digit (7) from the dividend, attach it to 268 and continue: 2687 / 429

Going ahead to step 7:
The number 429 fits into 2687 6 times, leaving a remainder of 113.
Use 6 as the next digit of our solution. 
Result so far: 4276.0
If we take 2574 away from 2687, we end up with 113.
Bring next digit (0) of the dividend behind the 113 and repeat the process: 1130 / 429

Moving on to step 8:
If we divide 1130 by 429, we get 2 and a remainder of 272.
Write down 2 as next digit of the result. 
Result so far: 42762.0
If we subtract 858 from 1130, we get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Step 9:
When dividing 2720 by 429, we get 6 with a remainder of 146.
Put 6 as the next digit of the answer. 
Result so far: 42762.6
Deduct 2574 from 2720 and we're left with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Advancing to step 10:
The number 429 fits into 1460 3 times, leaving a remainder of 173.
The next digit of our result is 3. 
Result so far: 42762.63
If we take 1287 away from 1460, we end up with 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Let's proceed to step 11:
If we divide 1730 by 429, we get 4 and a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 42762.634
Deduct 1716 from 1730 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 12:
429 can be fit into 140 0 times, resulting in a remainder of 140.
Record the quotient 0 as the next digit in the result. 
Result so far: 42762.634
Subtract 0 from 140 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 13:
429 can be fit into 1400 3 times, resulting in a remainder of 113.
Write down 3 as next digit of the result. 
Result so far: 42762.63403
Deduct 1287 from 1400 and we're left with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Going ahead to step 14:
When dividing 1130 by 429, we get 2 with a remainder of 272.
The number 2 becomes the next digit in our result. 
Result so far: 42762.634032
Deduct 858 from 1130 and we're left with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Step 15:
429 goes into 2720 6 times with a remainder of 146.
The number 6 becomes the next digit in our result. 
Result so far: 42762.6340326
If we subtract 2574 from 2720, we get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Moving on to step 16:
1460 divided by 429 is 3 with a remainder of 173.
Record the quotient 3 as the next digit in the result. 
Result so far: 42762.63403263
If we take 1287 away from 1460, we end up with 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Our division results in 42762.63403263 with a remaining 1.73e-07.
