Let's divide 86435478 by 220
Let's see how many times 220 fits into 86435478.

Advancing to step 1:
220 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 220

Moving on to step 2:
The number 220 fits into 86 0 times, leaving a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Fetch the next digit (4) from the dividend, attach it to 86 and continue: 864 / 220

Moving on to step 3:
When dividing 864 by 220, we get 3 with a remainder of 204.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 660 from 864 leaves us with 204.
Append the next digit (3) from the dividend to 204 and continue with: 2043 / 220

Moving on to step 4:
220 can be fit into 2043 9 times, resulting in a remainder of 63.
Put 9 as the next digit of the answer. 
Result so far: 39.0
Subtract 1980 from 2043 to get 63.
Include the next digit (5) from the dividend after 63, then repeat: 635 / 220

Going ahead to step 5:
220 can be fit into 635 2 times, resulting in a remainder of 195.
Use 2 as the next digit of our solution. 
Result so far: 392.0
Subtracting 440 from 635 leaves us with 195.
Append the next digit (4) from the dividend to 195 and continue with: 1954 / 220

Going ahead to step 6:
The number 220 fits into 1954 8 times, leaving a remainder of 194.
Put 8 as the next digit of the answer. 
Result so far: 3928.0
Subtracting 1760 from 1954 leaves us with 194.
Append the next digit (7) from the dividend to 194 and continue with: 1947 / 220

Going ahead to step 7:
220 can be fit into 1947 8 times, resulting in a remainder of 187.
Write down 8 as next digit of the result. 
Result so far: 39288.0
Subtracting 1760 from 1947 leaves us with 187.
Bring next digit (8) of the dividend behind the 187 and repeat the process: 1878 / 220

Going ahead to step 8:
220 goes into 1878 8 times with a remainder of 118.
The number 8 becomes the next digit in our result. 
Result so far: 392888.0
Subtract 1760 from 1878 to get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Step 9:
The number 220 fits into 1180 5 times, leaving a remainder of 80.
Write down 5 as next digit of the result. 
Result so far: 392888.5
Deduct 1100 from 1180 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 10:
220 can be fit into 800 3 times, resulting in a remainder of 140.
Record the quotient 3 as the next digit in the result. 
Result so far: 392888.53
Subtracting 660 from 800 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 11:
The number 220 fits into 1400 6 times, leaving a remainder of 80.
The number 6 becomes the next digit in our result. 
Result so far: 392888.536
If we take 1320 away from 1400, we end up 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.

Going ahead to step 12:
220 can be fit into 800 3 times, resulting in a remainder of 140.
The next digit of our result is 3. 
Result so far: 392888.5363
The remainder is 140 after subtracting 660 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 13:
220 goes into 1400 6 times with a remainder of 80.
Use 6 as the next digit of our solution. 
Result so far: 392888.53636
Subtracting 1320 from 1400 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 14:
When dividing 800 by 220, we get 3 with a remainder of 140.
The number 3 becomes the next digit in our result. 
Result so far: 392888.536363
The remainder is 140 after subtracting 660 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 15:
220 goes into 1400 6 times with a remainder of 80.
Use 6 as the next digit of our solution. 
Result so far: 392888.5363636
Subtracting 1320 from 1400 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 16:
220 can be fit into 800 3 times, resulting in a remainder of 140.
Use 3 as the next digit of our solution. 
Result so far: 392888.53636363
If we take 660 away from 800, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

The quotient of the division is 392888.53636363, and the remainder is 1.4e-07.
