64603902 divided by 187 
We want to figure out the number of times 64603902 can be divided by 187.

Advancing to step 1:
6 divided by 187 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 187

Going ahead to step 2:
187 goes into 64 0 times with a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Grab the next digit (6) from the dividend, add it to 64, then carry on: 646 / 187

Going ahead to step 3:
646 divided by 187 is 3 with a remainder of 85.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 561 from 646 leaves us with 85.
Include the next digit (0) from the dividend after 85, then repeat: 850 / 187

Step 4:
If we divide 850 by 187, we get 4 and a remainder of 102.
Put 4 as the next digit of the answer. 
Result so far: 34.0
If we take 748 away from 850, we end up with 102.
Include the next digit (3) from the dividend after 102, then repeat: 1023 / 187

Let's proceed to step 5:
If we divide 1023 by 187, we get 5 and a remainder of 88.
Use 5 as the next digit of our solution. 
Result so far: 345.0
If we take 935 away from 1023, we end up with 88.
Grab the next digit (9) from the dividend, add it to 88, then carry on: 889 / 187

Step 6:
889 divided by 187 is 4 with a remainder of 141.
Write down 4 as next digit of the result. 
Result so far: 3454.0
Deduct 748 from 889 and we're left with 141.
Bring next digit (0) of the dividend behind the 141 and repeat the process: 1410 / 187

Moving on to step 7:
The number 187 fits into 1410 7 times, leaving a remainder of 101.
The number 7 becomes the next digit in our result. 
Result so far: 34547.0
The remainder is 101 after subtracting 1309 from 1410.
Fetch the next digit (2) from the dividend, attach it to 101 and continue: 1012 / 187

Moving on to step 8:
187 goes into 1012 5 times with a remainder of 77.
Record the quotient 5 as the next digit in the result. 
Result so far: 345475.0
The remainder is 77 after subtracting 935 from 1012.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Let's proceed to step 9:
187 can be fit into 770 4 times, resulting in a remainder of 22.
The number 4 becomes the next digit in our result. 
Result so far: 345475.4
If we subtract 748 from 770, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 10:
187 goes into 220 1 times with a remainder of 33.
Write down 1 as next digit of the result. 
Result so far: 345475.41
Deduct 187 from 220 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 11:
330 divided by 187 is 1 with a remainder of 143.
The next digit of our result is 1. 
Result so far: 345475.411
The remainder is 143 after subtracting 187 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

In conclusion, the division gives 345475.411 with a balance of 0.0143.
