Let's divide 63921547 by 428
Our goal is to divide 63921547 by 428.

Advancing to step 1:
428 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 428

Moving on to step 2:
The number 428 fits into 63 0 times, leaving a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Take the next digit (9) from the dividend and append it to 63, then repeat: 639 / 428

Moving on to step 3:
428 can be fit into 639 1 times, resulting in a remainder of 211.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 428 from 639 and we're left with 211.
Take the next digit (2) from the dividend and append it to 211, then repeat: 2112 / 428

Moving on to step 4:
2112 divided by 428 is 4 with a remainder of 400.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Deduct 1712 from 2112 and we're left with 400.
Include the next digit (1) from the dividend after 400, then repeat: 4001 / 428

Going ahead to step 5:
428 goes into 4001 9 times with a remainder of 149.
Record the quotient 9 as the next digit in the result. 
Result so far: 149.0
If we subtract 3852 from 4001, we get 149.
Fetch the next digit (5) from the dividend, attach it to 149 and continue: 1495 / 428

Moving on to step 6:
428 goes into 1495 3 times with a remainder of 211.
Write down 3 as next digit of the result. 
Result so far: 1493.0
Deduct 1284 from 1495 and we're left with 211.
Append the next digit (4) from the dividend to 211 and continue with: 2114 / 428

On to step 7:
The number 428 fits into 2114 4 times, leaving a remainder of 402.
The number 4 becomes the next digit in our result. 
Result so far: 14934.0
If we subtract 1712 from 2114, we get 402.
Take the next digit (7) from the dividend and append it to 402, then repeat: 4027 / 428

Moving on to step 8:
The number 428 fits into 4027 9 times, leaving a remainder of 175.
The number 9 becomes the next digit in our result. 
Result so far: 149349.0
If we take 3852 away from 4027, we end up with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Advancing to step 9:
1750 divided by 428 is 4 with a remainder of 38.
Write down 4 as next digit of the result. 
Result so far: 149349.4
If we subtract 1712 from 1750, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 10:
428 goes into 380 0 times with a remainder of 380.
Write down 0 as next digit of the result. 
Result so far: 149349.4
Deduct 0 from 380 and we're left with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Advancing to step 11:
428 goes into 3800 8 times with a remainder of 376.
The number 8 becomes the next digit in our result. 
Result so far: 149349.408
If we subtract 3424 from 3800, we get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Step 12:
When dividing 3760 by 428, we get 8 with a remainder of 336.
Put 8 as the next digit of the answer. 
Result so far: 149349.4088
Subtract 3424 from 3760 to get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

In conclusion, the division gives 149349.4088 with a balance of 0.00336.
