Let's divide 83419378 by 664
Our goal is to divide 83419378 by 664.

On to step 1:
664 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 664

Moving on to step 2:
664 goes into 83 0 times with a remainder of 83.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 83 after subtracting 0 from 83.
Include the next digit (4) from the dividend after 83, then repeat: 834 / 664

Let's proceed to step 3:
If we divide 834 by 664, we get 1 and a remainder of 170.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 664 from 834 to get 170.
Take the next digit (1) from the dividend and append it to 170, then repeat: 1701 / 664

On to step 4:
The number 664 fits into 1701 2 times, leaving a remainder of 373.
The next digit of our result is 2. 
Result so far: 12.0
If we take 1328 away from 1701, we end up with 373.
Grab the next digit (9) from the dividend, add it to 373, then carry on: 3739 / 664

On to step 5:
3739 divided by 664 is 5 with a remainder of 419.
Write down 5 as next digit of the result. 
Result so far: 125.0
Deduct 3320 from 3739 and we're left with 419.
Take the next digit (3) from the dividend and append it to 419, then repeat: 4193 / 664

Going ahead to step 6:
The number 664 fits into 4193 6 times, leaving a remainder of 209.
Write down 6 as next digit of the result. 
Result so far: 1256.0
Subtracting 3984 from 4193 leaves us with 209.
Grab the next digit (7) from the dividend, add it to 209, then carry on: 2097 / 664

Going ahead to step 7:
If we divide 2097 by 664, we get 3 and a remainder of 105.
Put 3 as the next digit of the answer. 
Result so far: 12563.0
Deduct 1992 from 2097 and we're left with 105.
Take the next digit (8) from the dividend and append it to 105, then repeat: 1058 / 664

Let's proceed to step 8:
664 goes into 1058 1 times with a remainder of 394.
Use 1 as the next digit of our solution. 
Result so far: 125631.0
Subtracting 664 from 1058 leaves us with 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

On to step 9:
3940 divided by 664 is 5 with a remainder of 620.
Write down 5 as next digit of the result. 
Result so far: 125631.5
If we take 3320 away from 3940, we end up with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Going ahead to step 10:
664 goes into 6200 9 times with a remainder of 224.
Use 9 as the next digit of our solution. 
Result so far: 125631.59
Subtracting 5976 from 6200 leaves us with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Let's proceed to step 11:
When dividing 2240 by 664, we get 3 with a remainder of 248.
Use 3 as the next digit of our solution. 
Result so far: 125631.593
Subtract 1992 from 2240 to get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

On to step 12:
664 can be fit into 2480 3 times, resulting in a remainder of 488.
Record the quotient 3 as the next digit in the result. 
Result so far: 125631.5933
The remainder is 488 after subtracting 1992 from 2480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

The final outcome is 125631.5933, with a leftover of 0.00488.
