We're dividing 86164543 by 437 
We want to figure out the number of times 86164543 can be divided by 437.

Let's proceed to step 1:
When dividing 8 by 437, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 437

Step 2:
437 can be fit into 86 0 times, resulting in a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Include the next digit (1) from the dividend after 86, then repeat: 861 / 437

Advancing to step 3:
If we divide 861 by 437, we get 1 and a remainder of 424.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 437 away from 861, we end up with 424.
Grab the next digit (6) from the dividend, add it to 424, then carry on: 4246 / 437

Moving on to step 4:
The number 437 fits into 4246 9 times, leaving a remainder of 313.
The next digit of our result is 9. 
Result so far: 19.0
Deduct 3933 from 4246 and we're left with 313.
Append the next digit (4) from the dividend to 313 and continue with: 3134 / 437

Advancing to step 5:
If we divide 3134 by 437, we get 7 and a remainder of 75.
The number 7 becomes the next digit in our result. 
Result so far: 197.0
Subtract 3059 from 3134 to get 75.
Bring next digit (5) of the dividend behind the 75 and repeat the process: 755 / 437

Moving on to step 6:
The number 437 fits into 755 1 times, leaving a remainder of 318.
Use 1 as the next digit of our solution. 
Result so far: 1971.0
The remainder is 318 after subtracting 437 from 755.
Fetch the next digit (4) from the dividend, attach it to 318 and continue: 3184 / 437

Moving on to step 7:
3184 divided by 437 is 7 with a remainder of 125.
Put 7 as the next digit of the answer. 
Result so far: 19717.0
The remainder is 125 after subtracting 3059 from 3184.
Grab the next digit (3) from the dividend, add it to 125, then carry on: 1253 / 437

Advancing to step 8:
1253 divided by 437 is 2 with a remainder of 379.
Use 2 as the next digit of our solution. 
Result so far: 197172.0
Subtract 874 from 1253 to get 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

Step 9:
3790 divided by 437 is 8 with a remainder of 294.
Write down 8 as next digit of the result. 
Result so far: 197172.8
Subtract 3496 from 3790 to get 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Advancing to step 10:
437 can be fit into 2940 6 times, resulting in a remainder of 318.
Write down 6 as next digit of the result. 
Result so far: 197172.86
The remainder is 318 after subtracting 2622 from 2940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Moving on to step 11:
When dividing 3180 by 437, we get 7 with a remainder of 121.
Write down 7 as next digit of the result. 
Result so far: 197172.867
The remainder is 121 after subtracting 3059 from 3180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Moving on to step 12:
437 goes into 1210 2 times with a remainder of 336.
The next digit of our result is 2. 
Result so far: 197172.8672
Subtracting 874 from 1210 leaves us with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Moving on to step 13:
If we divide 3360 by 437, we get 7 and a remainder of 301.
The next digit of our result is 7. 
Result so far: 197172.86727
Deduct 3059 from 3360 and we're left with 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Step 14:
3010 divided by 437 is 6 with a remainder of 388.
The number 6 becomes the next digit in our result. 
Result so far: 197172.867276
The remainder is 388 after subtracting 2622 from 3010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Advancing to step 15:
437 goes into 3880 8 times with a remainder of 384.
Put 8 as the next digit of the answer. 
Result so far: 197172.8672768
Deduct 3496 from 3880 and we're left with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Advancing to step 16:
437 goes into 3840 8 times with a remainder of 344.
The number 8 becomes the next digit in our result. 
Result so far: 197172.86727688
The remainder is 344 after subtracting 3496 from 3840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

The quotient of the division is 197172.86727688, and the remainder is 3.44e-07.
