745 goes into 66 0 times with a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Fetch the next digit (6) from the dividend, attach it to 66 and continue: 666 / 745

Advancing to step 3:
745 goes into 666 0 times with a remainder of 666.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 666, we end up with 666.
Fetch the next digit (8) from the dividend, attach it to 666 and continue: 6668 / 745

Advancing to step 4:
6668 divided by 745 is 8 with a remainder of 708.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 5960 away from 6668, we end up with 708.
Fetch the next digit (5) from the dividend, attach it to 708 and continue: 7085 / 745

Advancing to step 5:
If we divide 7085 by 745, we get 9 and a remainder of 380.
The next digit of our result is 9. 
Result so far: 89.0
The remainder is 380 after subtracting 6705 from 7085.
Grab the next digit (6) from the dividend, add it to 380, then carry on: 3806 / 745

Going ahead to step 6:
The number 745 fits into 3806 5 times, leaving a remainder of 81.
The number 5 becomes the next digit in our result. 
Result so far: 895.0
Deduct 3725 from 3806 and we're left with 81.
Include the next digit (3) from the dividend after 81, then repeat: 813 / 745

Going ahead to step 7:
The number 745 fits into 813 1 times, leaving a remainder of 68.
Record the quotient 1 as the next digit in the result. 
Result so far: 8951.0
Deduct 745 from 813 and we're left with 68.
Grab the next digit (1) from the dividend, add it to 68, then carry on: 681 / 745

Let's proceed to step 8:
745 can be fit into 681 0 times, resulting in a remainder of 681.
Write down 0 as next digit of the result. 
Result so far: 89510.0
Subtracting 0 from 681 leaves us with 681.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6810, and continue the process.

Going ahead to step 9:
If we divide 6810 by 745, we get 9 and a remainder of 105.
Put 9 as the next digit of the answer. 
Result so far: 89510.9
If we subtract 6705 from 6810, we get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Step 10:
The number 745 fits into 1050 1 times, leaving a remainder of 305.
The next digit of our result is 1. 
Result so far: 89510.91
If we subtract 745 from 1050, we get 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

On to step 11:
The number 745 fits into 3050 4 times, leaving a remainder of 70.
Write down 4 as next digit of the result. 
Result so far: 89510.914
Deduct 2980 from 3050 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 12:
The number 745 fits into 700 0 times, leaving a remainder of 700.
The number 0 becomes the next digit in our result. 
Result so far: 89510.914
If we subtract 0 from 700, we get 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Advancing to step 13:
745 goes into 7000 9 times with a remainder of 295.
Record the quotient 9 as the next digit in the result. 
Result so far: 89510.91409
Subtracting 6705 from 7000 leaves us with 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Advancing to step 14:
2950 divided by 745 is 3 with a remainder of 715.
Put 3 as the next digit of the answer. 
Result so far: 89510.914093
Deduct 2235 from 2950 and we're left with 715.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7150, and continue the process.

Step 15:
745 can be fit into 7150 9 times, resulting in a remainder of 445.
Record the quotient 9 as the next digit in the result. 
Result so far: 89510.9140939
If we take 6705 away from 7150, we end up with 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Moving on to step 16:
4450 divided by 745 is 5 with a remainder of 725.
The next digit of our result is 5. 
Result so far: 89510.91409395
Subtract 3725 from 4450 to get 725.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7250, and continue the process.

In conclusion, the division gives 89510.91409395 with a balance of 7.25e-07.
