78390170 divided by 466 
We're looking to find how many times 466 goes into 78390170.

Going ahead to step 1:
7 divided by 466 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 466

Moving on to step 2:
If we divide 78 by 466, we get 0 and a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Append the next digit (3) from the dividend to 78 and continue with: 783 / 466

Let's proceed to step 3:
If we divide 783 by 466, we get 1 and a remainder of 317.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 317 after subtracting 466 from 783.
Include the next digit (9) from the dividend after 317, then repeat: 3179 / 466

Step 4:
If we divide 3179 by 466, we get 6 and a remainder of 383.
The next digit of our result is 6. 
Result so far: 16.0
If we take 2796 away from 3179, we end up with 383.
Bring next digit (0) of the dividend behind the 383 and repeat the process: 3830 / 466

Going ahead to step 5:
The number 466 fits into 3830 8 times, leaving a remainder of 102.
Use 8 as the next digit of our solution. 
Result so far: 168.0
Deduct 3728 from 3830 and we're left with 102.
Take the next digit (1) from the dividend and append it to 102, then repeat: 1021 / 466

Let's proceed to step 6:
When dividing 1021 by 466, we get 2 with a remainder of 89.
The number 2 becomes the next digit in our result. 
Result so far: 1682.0
Deduct 932 from 1021 and we're left with 89.
Bring next digit (7) of the dividend behind the 89 and repeat the process: 897 / 466

Let's proceed to step 7:
When dividing 897 by 466, we get 1 with a remainder of 431.
The next digit of our result is 1. 
Result so far: 16821.0
Subtracting 466 from 897 leaves us with 431.
Bring next digit (0) of the dividend behind the 431 and repeat the process: 4310 / 466

On to step 8:
466 can be fit into 4310 9 times, resulting in a remainder of 116.
The next digit of our result is 9. 
Result so far: 168219.0
Deduct 4194 from 4310 and we're left with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Step 9:
The number 466 fits into 1160 2 times, leaving a remainder of 228.
Use 2 as the next digit of our solution. 
Result so far: 168219.2
If we subtract 932 from 1160, we get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Going ahead to step 10:
When dividing 2280 by 466, we get 4 with a remainder of 416.
Write down 4 as next digit of the result. 
Result so far: 168219.24
The remainder is 416 after subtracting 1864 from 2280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Advancing to step 11:
466 can be fit into 4160 8 times, resulting in a remainder of 432.
The next digit of our result is 8. 
Result so far: 168219.248
If we take 3728 away from 4160, we end up with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Going ahead to step 12:
4320 divided by 466 is 9 with a remainder of 126.
Record the quotient 9 as the next digit in the result. 
Result so far: 168219.2489
Subtract 4194 from 4320 to get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Advancing to step 13:
1260 divided by 466 is 2 with a remainder of 328.
The number 2 becomes the next digit in our result. 
Result so far: 168219.24892
If we take 932 away from 1260, we end up with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

On to step 14:
466 can be fit into 3280 7 times, resulting in a remainder of 18.
Use 7 as the next digit of our solution. 
Result so far: 168219.248927
Deduct 3262 from 3280 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 15:
If we divide 180 by 466, we get 0 and a remainder of 180.
Record the quotient 0 as the next digit in the result. 
Result so far: 168219.248927
If we take 0 away from 180, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

On to step 16:
466 can be fit into 1800 3 times, resulting in a remainder of 402.
Put 3 as the next digit of the answer. 
Result so far: 168219.24892703
Subtracting 1398 from 1800 leaves us with 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

The final result is 168219.24892703 with a remainder of 4.02e-07.
