84090138 ÷ 196 
We want to divide 84090138 by 196.

Let's proceed to step 1:
196 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 196

Step 2:
When dividing 84 by 196, we get 0 with a remainder of 84.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 84 to get 84.
Include the next digit (0) from the dividend after 84, then repeat: 840 / 196

Step 3:
196 goes into 840 4 times with a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 56 after subtracting 784 from 840.
Include the next digit (9) from the dividend after 56, then repeat: 569 / 196

Moving on to step 4:
The number 196 fits into 569 2 times, leaving a remainder of 177.
Write down 2 as next digit of the result. 
Result so far: 42.0
If we take 392 away from 569, we end up with 177.
Take the next digit (0) from the dividend and append it to 177, then repeat: 1770 / 196

Let's proceed to step 5:
196 can be fit into 1770 9 times, resulting in a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 429.0
Subtract 1764 from 1770 to get 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 196

Going ahead to step 6:
196 can be fit into 61 0 times, resulting in a remainder of 61.
The number 0 becomes the next digit in our result. 
Result so far: 4290.0
Subtracting 0 from 61 leaves us with 61.
Bring next digit (3) of the dividend behind the 61 and repeat the process: 613 / 196

Advancing to step 7:
196 goes into 613 3 times with a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 42903.0
If we subtract 588 from 613, we get 25.
Take the next digit (8) from the dividend and append it to 25, then repeat: 258 / 196

Let's proceed to step 8:
196 can be fit into 258 1 times, resulting in a remainder of 62.
Write down 1 as next digit of the result. 
Result so far: 429031.0
If we subtract 196 from 258, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 9:
196 can be fit into 620 3 times, resulting in a remainder of 32.
Use 3 as the next digit of our solution. 
Result so far: 429031.3
If we subtract 588 from 620, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 10:
The number 196 fits into 320 1 times, leaving a remainder of 124.
The number 1 becomes the next digit in our result. 
Result so far: 429031.31
If we take 196 away from 320, we end up with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Step 11:
1240 divided by 196 is 6 with a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 429031.316
Deduct 1176 from 1240 and we're left 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.

Going ahead to step 12:
If we divide 640 by 196, we get 3 and a remainder of 52.
The next digit of our result is 3. 
Result so far: 429031.3163
Deduct 588 from 640 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 13:
The number 196 fits into 520 2 times, leaving a remainder of 128.
Record the quotient 2 as the next digit in the result. 
Result so far: 429031.31632
Subtracting 392 from 520 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

On to step 14:
1280 divided by 196 is 6 with a remainder of 104.
The next digit of our result is 6. 
Result so far: 429031.316326
If we take 1176 away from 1280, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Let's proceed to step 15:
When dividing 1040 by 196, we get 5 with a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 429031.3163265
If we subtract 980 from 1040, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 16:
When dividing 600 by 196, we get 3 with a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 429031.31632653
The remainder is 12 after subtracting 588 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

In conclusion, the division gives 429031.31632653 with a balance of 1.2e-08.
