745 goes into 4521 6 times with a remainder of 51.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 51 after subtracting 4470 from 4521.
Include the next digit (0) from the dividend after 51, then repeat: 510 / 745

Let's proceed to step 5:
If we divide 510 by 745, we get 0 and a remainder of 510.
Use 0 as the next digit of our solution. 
Result so far: 60.0
If we subtract 0 from 510, we get 510.
Include the next digit (9) from the dividend after 510, then repeat: 5109 / 745

Moving on to step 6:
The number 745 fits into 5109 6 times, leaving a remainder of 639.
Use 6 as the next digit of our solution. 
Result so far: 606.0
If we take 4470 away from 5109, we end up with 639.
Take the next digit (6) from the dividend and append it to 639, then repeat: 6396 / 745

On to step 7:
The number 745 fits into 6396 8 times, leaving a remainder of 436.
Write down 8 as next digit of the result. 
Result so far: 6068.0
Subtracting 5960 from 6396 leaves us with 436.
Include the next digit (1) from the dividend after 436, then repeat: 4361 / 745

Moving on to step 8:
4361 divided by 745 is 5 with a remainder of 636.
Record the quotient 5 as the next digit in the result. 
Result so far: 60685.0
Deduct 3725 from 4361 and we're left with 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

Moving on to step 9:
745 goes into 6360 8 times with a remainder of 400.
The number 8 becomes the next digit in our result. 
Result so far: 60685.8
If we take 5960 away from 6360, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 10:
745 goes into 4000 5 times with a remainder of 275.
Use 5 as the next digit of our solution. 
Result so far: 60685.85
If we subtract 3725 from 4000, we get 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Step 11:
When dividing 2750 by 745, we get 3 with a remainder of 515.
The number 3 becomes the next digit in our result. 
Result so far: 60685.853
If we take 2235 away from 2750, we end up with 515.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

Step 12:
5150 divided by 745 is 6 with a remainder of 680.
Record the quotient 6 as the next digit in the result. 
Result so far: 60685.8536
Deduct 4470 from 5150 and we're left with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Let's proceed to step 13:
When dividing 6800 by 745, we get 9 with a remainder of 95.
The number 9 becomes the next digit in our result. 
Result so far: 60685.85369
Subtract 6705 from 6800 to get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Moving on to step 14:
When dividing 950 by 745, we get 1 with a remainder of 205.
Put 1 as the next digit of the answer. 
Result so far: 60685.853691
Deduct 745 from 950 and we're left with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Advancing to step 15:
The number 745 fits into 2050 2 times, leaving a remainder of 560.
Write down 2 as next digit of the result. 
Result so far: 60685.8536912
Subtract 1490 from 2050 to get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Going ahead to step 16:
745 can be fit into 5600 7 times, resulting in a remainder of 385.
Record the quotient 7 as the next digit in the result. 
Result so far: 60685.85369127
Deduct 5215 from 5600 and we're left with 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Our division results in 60685.85369127 with a remaining 3.85e-07.
