67198389 ÷ 406 
Let's see how many times 406 fits into 67198389.

On to step 1:
If we divide 6 by 406, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 406

Advancing to step 2:
406 goes into 67 0 times with a remainder of 67.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 67 to get 67.
Bring next digit (1) of the dividend behind the 67 and repeat the process: 671 / 406

Advancing to step 3:
406 can be fit into 671 1 times, resulting in a remainder of 265.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 265 after subtracting 406 from 671.
Fetch the next digit (9) from the dividend, attach it to 265 and continue: 2659 / 406

Advancing to step 4:
The number 406 fits into 2659 6 times, leaving a remainder of 223.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtracting 2436 from 2659 leaves us with 223.
Include the next digit (8) from the dividend after 223, then repeat: 2238 / 406

Going ahead to step 5:
The number 406 fits into 2238 5 times, leaving a remainder of 208.
Put 5 as the next digit of the answer. 
Result so far: 165.0
If we subtract 2030 from 2238, we get 208.
Include the next digit (3) from the dividend after 208, then repeat: 2083 / 406

Moving on to step 6:
When dividing 2083 by 406, we get 5 with a remainder of 53.
The number 5 becomes the next digit in our result. 
Result so far: 1655.0
Subtract 2030 from 2083 to get 53.
Include the next digit (8) from the dividend after 53, then repeat: 538 / 406

Moving on to step 7:
406 can be fit into 538 1 times, resulting in a remainder of 132.
Put 1 as the next digit of the answer. 
Result so far: 16551.0
If we subtract 406 from 538, we get 132.
Grab the next digit (9) from the dividend, add it to 132, then carry on: 1329 / 406

Let's proceed to step 8:
When dividing 1329 by 406, we get 3 with a remainder of 111.
Use 3 as the next digit of our solution. 
Result so far: 165513.0
The remainder is 111 after subtracting 1218 from 1329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Going ahead to step 9:
406 can be fit into 1110 2 times, resulting in a remainder of 298.
Write down 2 as next digit of the result. 
Result so far: 165513.2
Subtract 812 from 1110 to get 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Let's proceed to step 10:
When dividing 2980 by 406, we get 7 with a remainder of 138.
The next digit of our result is 7. 
Result so far: 165513.27
Subtract 2842 from 2980 to get 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Going ahead to step 11:
When dividing 1380 by 406, we get 3 with a remainder of 162.
Record the quotient 3 as the next digit in the result. 
Result so far: 165513.273
Deduct 1218 from 1380 and we're left with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Step 12:
The number 406 fits into 1620 3 times, leaving a remainder of 402.
The number 3 becomes the next digit in our result. 
Result so far: 165513.2733
Deduct 1218 from 1620 and we're left with 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

The final result is 165513.2733 with a remainder of 0.00402.
