60721352 ÷ 406 
Let's see how many times 406 fits into 60721352.

On to step 1:
If we divide 6 by 406, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 406

On to step 2:
60 divided by 406 is 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 60 after subtracting 0 from 60.
Take the next digit (7) from the dividend and append it to 60, then repeat: 607 / 406

Let's proceed to step 3:
607 divided by 406 is 1 with a remainder of 201.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 406 away from 607, we end up with 201.
Take the next digit (2) from the dividend and append it to 201, then repeat: 2012 / 406

Moving on to step 4:
2012 divided by 406 is 4 with a remainder of 388.
Write down 4 as next digit of the result. 
Result so far: 14.0
Subtracting 1624 from 2012 leaves us with 388.
Bring next digit (1) of the dividend behind the 388 and repeat the process: 3881 / 406

Advancing to step 5:
406 can be fit into 3881 9 times, resulting in a remainder of 227.
The number 9 becomes the next digit in our result. 
Result so far: 149.0
If we subtract 3654 from 3881, we get 227.
Include the next digit (3) from the dividend after 227, then repeat: 2273 / 406

Advancing to step 6:
406 goes into 2273 5 times with a remainder of 243.
Write down 5 as next digit of the result. 
Result so far: 1495.0
Deduct 2030 from 2273 and we're left with 243.
Take the next digit (5) from the dividend and append it to 243, then repeat: 2435 / 406

Moving on to step 7:
The number 406 fits into 2435 5 times, leaving a remainder of 405.
Use 5 as the next digit of our solution. 
Result so far: 14955.0
The remainder is 405 after subtracting 2030 from 2435.
Bring next digit (2) of the dividend behind the 405 and repeat the process: 4052 / 406

Step 8:
406 goes into 4052 9 times with a remainder of 398.
Use 9 as the next digit of our solution. 
Result so far: 149559.0
Subtracting 3654 from 4052 leaves us with 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Going ahead to step 9:
406 can be fit into 3980 9 times, resulting in a remainder of 326.
Use 9 as the next digit of our solution. 
Result so far: 149559.9
Subtract 3654 from 3980 to get 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Let's proceed to step 10:
3260 divided by 406 is 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 149559.98
If we subtract 3248 from 3260, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 11:
120 divided by 406 is 0 with a remainder of 120.
The number 0 becomes the next digit in our result. 
Result so far: 149559.98
Deduct 0 from 120 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 12:
The number 406 fits into 1200 2 times, leaving a remainder of 388.
Put 2 as the next digit of the answer. 
Result so far: 149559.9802
Subtract 812 from 1200 to get 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Let's proceed to step 13:
406 goes into 3880 9 times with a remainder of 226.
The number 9 becomes the next digit in our result. 
Result so far: 149559.98029
If we subtract 3654 from 3880, we get 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Moving on to step 14:
2260 divided by 406 is 5 with a remainder of 230.
Put 5 as the next digit of the answer. 
Result so far: 149559.980295
The remainder is 230 after subtracting 2030 from 2260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 15:
The number 406 fits into 2300 5 times, leaving a remainder of 270.
Record the quotient 5 as the next digit in the result. 
Result so far: 149559.9802955
The remainder is 270 after subtracting 2030 from 2300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

In conclusion, the division gives 149559.9802955 with a balance of 2.7e-06.
