We look at the division of 64166769 by 748 
Let's see how many times 748 fits into 64166769.

Going ahead to step 1:
6 divided by 748 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 748

Moving on to step 2:
If we divide 64 by 748, we get 0 and a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Bring next digit (1) of the dividend behind the 64 and repeat the process: 641 / 748

Moving on to step 3:
When dividing 641 by 748, we get 0 with a remainder of 641.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 641, we get 641.
Grab the next digit (6) from the dividend, add it to 641, then carry on: 6416 / 748

Step 4:
When dividing 6416 by 748, we get 8 with a remainder of 432.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 5984 from 6416, we get 432.
Bring next digit (6) of the dividend behind the 432 and repeat the process: 4326 / 748

Going ahead to step 5:
If we divide 4326 by 748, we get 5 and a remainder of 586.
Write down 5 as next digit of the result. 
Result so far: 85.0
Subtracting 3740 from 4326 leaves us with 586.
Append the next digit (7) from the dividend to 586 and continue with: 5867 / 748

Step 6:
5867 divided by 748 is 7 with a remainder of 631.
Put 7 as the next digit of the answer. 
Result so far: 857.0
Subtracting 5236 from 5867 leaves us with 631.
Include the next digit (6) from the dividend after 631, then repeat: 6316 / 748

Advancing to step 7:
When dividing 6316 by 748, we get 8 with a remainder of 332.
Use 8 as the next digit of our solution. 
Result so far: 8578.0
The remainder is 332 after subtracting 5984 from 6316.
Take the next digit (9) from the dividend and append it to 332, then repeat: 3329 / 748

Step 8:
748 can be fit into 3329 4 times, resulting in a remainder of 337.
Write down 4 as next digit of the result. 
Result so far: 85784.0
Subtract 2992 from 3329 to get 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

On to step 9:
If we divide 3370 by 748, we get 4 and a remainder of 378.
The number 4 becomes the next digit in our result. 
Result so far: 85784.4
Subtracting 2992 from 3370 leaves us with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Let's proceed to step 10:
The number 748 fits into 3780 5 times, leaving a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 85784.45
The remainder is 40 after subtracting 3740 from 3780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 11:
The number 748 fits into 400 0 times, leaving a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 85784.45
Subtract 0 from 400 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Advancing to step 12:
When dividing 4000 by 748, we get 5 with a remainder of 260.
Record the quotient 5 as the next digit in the result. 
Result so far: 85784.4505
If we take 3740 away from 4000, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

On to step 13:
When dividing 2600 by 748, we get 3 with a remainder of 356.
Use 3 as the next digit of our solution. 
Result so far: 85784.45053
The remainder is 356 after subtracting 2244 from 2600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Advancing to step 14:
3560 divided by 748 is 4 with a remainder of 568.
The number 4 becomes the next digit in our result. 
Result so far: 85784.450534
The remainder is 568 after subtracting 2992 from 3560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

On to step 15:
If we divide 5680 by 748, we get 7 and a remainder of 444.
The next digit of our result is 7. 
Result so far: 85784.4505347
The remainder is 444 after subtracting 5236 from 5680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Let's proceed to step 16:
The number 748 fits into 4440 5 times, leaving a remainder of 700.
The number 5 becomes the next digit in our result. 
Result so far: 85784.45053475
If we take 3740 away from 4440, we end up with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

The final outcome is 85784.45053475, with a leftover of 7e-07.
