6209991 divided by 401 
Our goal is to divide 6209991 by 401.

Step 1:
The number 401 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 401

On to step 2:
The number 401 fits into 62 0 times, leaving a remainder of 62.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 62 and we're left with 62.
Fetch the next digit (0) from the dividend, attach it to 62 and continue: 620 / 401

Step 3:
When dividing 620 by 401, we get 1 with a remainder of 219.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 401 from 620 to get 219.
Bring next digit (9) of the dividend behind the 219 and repeat the process: 2199 / 401

Advancing to step 4:
401 can be fit into 2199 5 times, resulting in a remainder of 194.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtracting 2005 from 2199 leaves us with 194.
Fetch the next digit (9) from the dividend, attach it to 194 and continue: 1949 / 401

Let's proceed to step 5:
If we divide 1949 by 401, we get 4 and a remainder of 345.
Write down 4 as next digit of the result. 
Result so far: 154.0
If we subtract 1604 from 1949, we get 345.
Take the next digit (9) from the dividend and append it to 345, then repeat: 3459 / 401

Step 6:
If we divide 3459 by 401, we get 8 and a remainder of 251.
Write down 8 as next digit of the result. 
Result so far: 1548.0
Deduct 3208 from 3459 and we're left with 251.
Append the next digit (1) from the dividend to 251 and continue with: 2511 / 401

Step 7:
2511 divided by 401 is 6 with a remainder of 105.
Use 6 as the next digit of our solution. 
Result so far: 15486.0
If we subtract 2406 from 2511, we get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Moving on to step 8:
401 goes into 1050 2 times with a remainder of 248.
Record the quotient 2 as the next digit in the result. 
Result so far: 15486.2
Subtracting 802 from 1050 leaves us with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

On to step 9:
When dividing 2480 by 401, we get 6 with a remainder of 74.
The next digit of our result is 6. 
Result so far: 15486.26
Subtract 2406 from 2480 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 10:
401 goes into 740 1 times with a remainder of 339.
Record the quotient 1 as the next digit in the result. 
Result so far: 15486.261
Subtract 401 from 740 to get 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

Let's proceed to step 11:
The number 401 fits into 3390 8 times, leaving a remainder of 182.
Write down 8 as next digit of the result. 
Result so far: 15486.2618
Deduct 3208 from 3390 and we're left with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Moving on to step 12:
1820 divided by 401 is 4 with a remainder of 216.
The next digit of our result is 4. 
Result so far: 15486.26184
If we subtract 1604 from 1820, we get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Moving on to step 13:
401 can be fit into 2160 5 times, resulting in a remainder of 155.
The number 5 becomes the next digit in our result. 
Result so far: 15486.261845
If we subtract 2005 from 2160, we get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Advancing to step 14:
The number 401 fits into 1550 3 times, leaving a remainder of 347.
The number 3 becomes the next digit in our result. 
Result so far: 15486.2618453
If we take 1203 away from 1550, we end up with 347.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3470, and continue the process.

Moving on to step 15:
When dividing 3470 by 401, we get 8 with a remainder of 262.
Write down 8 as next digit of the result. 
Result so far: 15486.26184538
If we take 3208 away from 3470, we end up with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Our division results in 15486.26184538 with a remaining 2.62e-07.
