34210513 divided by 401 
We want to figure out the number of times 34210513 can be divided by 401.

Step 1:
If we divide 3 by 401, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 401

Advancing to step 2:
34 divided by 401 is 0 with a remainder of 34.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 34 to get 34.
Grab the next digit (2) from the dividend, add it to 34, then carry on: 342 / 401

Moving on to step 3:
342 divided by 401 is 0 with a remainder of 342.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 342, we end up with 342.
Fetch the next digit (1) from the dividend, attach it to 342 and continue: 3421 / 401

Moving on to step 4:
When dividing 3421 by 401, we get 8 with a remainder of 213.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtracting 3208 from 3421 leaves us with 213.
Append the next digit (0) from the dividend to 213 and continue with: 2130 / 401

Moving on to step 5:
The number 401 fits into 2130 5 times, leaving a remainder of 125.
The next digit of our result is 5. 
Result so far: 85.0
If we subtract 2005 from 2130, we get 125.
Include the next digit (5) from the dividend after 125, then repeat: 1255 / 401

On to step 6:
When dividing 1255 by 401, we get 3 with a remainder of 52.
Use 3 as the next digit of our solution. 
Result so far: 853.0
The remainder is 52 after subtracting 1203 from 1255.
Append the next digit (1) from the dividend to 52 and continue with: 521 / 401

Advancing to step 7:
401 goes into 521 1 times with a remainder of 120.
Put 1 as the next digit of the answer. 
Result so far: 8531.0
If we subtract 401 from 521, we get 120.
Bring next digit (3) of the dividend behind the 120 and repeat the process: 1203 / 401

On to step 8:
401 can be fit into 1203 3 times, resulting in a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 85313.0
If we take 1203 away from 1203, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
0 divided by 401 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 85313.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
The number 401 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 85313.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 85313.0 with a balance of 0.0.
