We divide 63758146 by 521
Our goal is to divide 63758146 by 521.

Step 1:
The number 521 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 521

Moving on to step 2:
521 can be fit into 63 0 times, resulting in a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 63 to get 63.
Bring next digit (7) of the dividend behind the 63 and repeat the process: 637 / 521

Moving on to step 3:
521 can be fit into 637 1 times, resulting in a remainder of 116.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 521 from 637 leaves us with 116.
Include the next digit (5) from the dividend after 116, then repeat: 1165 / 521

Let's proceed to step 4:
521 can be fit into 1165 2 times, resulting in a remainder of 123.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtract 1042 from 1165 to get 123.
Include the next digit (8) from the dividend after 123, then repeat: 1238 / 521

Going ahead to step 5:
521 goes into 1238 2 times with a remainder of 196.
Record the quotient 2 as the next digit in the result. 
Result so far: 122.0
If we subtract 1042 from 1238, we get 196.
Include the next digit (1) from the dividend after 196, then repeat: 1961 / 521

Step 6:
If we divide 1961 by 521, we get 3 and a remainder of 398.
Record the quotient 3 as the next digit in the result. 
Result so far: 1223.0
The remainder is 398 after subtracting 1563 from 1961.
Take the next digit (4) from the dividend and append it to 398, then repeat: 3984 / 521

Step 7:
The number 521 fits into 3984 7 times, leaving a remainder of 337.
Use 7 as the next digit of our solution. 
Result so far: 12237.0
The remainder is 337 after subtracting 3647 from 3984.
Bring next digit (6) of the dividend behind the 337 and repeat the process: 3376 / 521

On to step 8:
When dividing 3376 by 521, we get 6 with a remainder of 250.
Write down 6 as next digit of the result. 
Result so far: 122376.0
Subtract 3126 from 3376 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Going ahead to step 9:
521 goes into 2500 4 times with a remainder of 416.
Use 4 as the next digit of our solution. 
Result so far: 122376.4
Subtract 2084 from 2500 to get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Moving on to step 10:
When dividing 4160 by 521, we get 7 with a remainder of 513.
The next digit of our result is 7. 
Result so far: 122376.47
Subtracting 3647 from 4160 leaves us with 513.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5130, and continue the process.

Let's proceed to step 11:
5130 divided by 521 is 9 with a remainder of 441.
Write down 9 as next digit of the result. 
Result so far: 122376.479
Subtracting 4689 from 5130 leaves us with 441.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4410, and continue the process.

Let's proceed to step 12:
The number 521 fits into 4410 8 times, leaving a remainder of 242.
Record the quotient 8 as the next digit in the result. 
Result so far: 122376.4798
Deduct 4168 from 4410 and we're left with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Let's proceed to step 13:
2420 divided by 521 is 4 with a remainder of 336.
Write down 4 as next digit of the result. 
Result so far: 122376.47984
Subtract 2084 from 2420 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.

Advancing to step 14:
The number 521 fits into 3360 6 times, leaving a remainder of 234.
Put 6 as the next digit of the answer. 
Result so far: 122376.479846
If we subtract 3126 from 3360, we get 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Moving on to step 15:
The number 521 fits into 2340 4 times, leaving a remainder of 256.
Write down 4 as next digit of the result. 
Result so far: 122376.4798464
If we take 2084 away from 2340, we end up with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Moving on to step 16:
If we divide 2560 by 521, we get 4 and a remainder of 476.
The number 4 becomes the next digit in our result. 
Result so far: 122376.47984644
The remainder is 476 after subtracting 2084 from 2560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

The final outcome is 122376.47984644, with a leftover of 4.76e-07.
