77474537 divided by 406 
We want to figure out the number of times 77474537 can be divided by 406.

Step 1:
7 divided by 406 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 406

On to step 2:
The number 406 fits into 77 0 times, leaving a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Grab the next digit (4) from the dividend, add it to 77, then carry on: 774 / 406

Step 3:
When dividing 774 by 406, we get 1 with a remainder of 368.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 368 after subtracting 406 from 774.
Append the next digit (7) from the dividend to 368 and continue with: 3687 / 406

Step 4:
406 goes into 3687 9 times with a remainder of 33.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Subtract 3654 from 3687 to get 33.
Fetch the next digit (4) from the dividend, attach it to 33 and continue: 334 / 406

On to step 5:
When dividing 334 by 406, we get 0 with a remainder of 334.
Record the quotient 0 as the next digit in the result. 
Result so far: 190.0
Subtracting 0 from 334 leaves us with 334.
Append the next digit (5) from the dividend to 334 and continue with: 3345 / 406

Step 6:
406 can be fit into 3345 8 times, resulting in a remainder of 97.
Write down 8 as next digit of the result. 
Result so far: 1908.0
Subtract 3248 from 3345 to get 97.
Bring next digit (3) of the dividend behind the 97 and repeat the process: 973 / 406

Going ahead to step 7:
406 can be fit into 973 2 times, resulting in a remainder of 161.
Put 2 as the next digit of the answer. 
Result so far: 19082.0
Subtract 812 from 973 to get 161.
Grab the next digit (7) from the dividend, add it to 161, then carry on: 1617 / 406

Let's proceed to step 8:
406 can be fit into 1617 3 times, resulting in a remainder of 399.
Put 3 as the next digit of the answer. 
Result so far: 190823.0
Deduct 1218 from 1617 and we're left with 399.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3990, and continue the process.

Let's proceed to step 9:
The number 406 fits into 3990 9 times, leaving a remainder of 336.
Put 9 as the next digit of the answer. 
Result so far: 190823.9
The remainder is 336 after subtracting 3654 from 3990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Moving on to step 10:
If we divide 3360 by 406, we get 8 and a remainder of 112.
The next digit of our result is 8. 
Result so far: 190823.98
Subtract 3248 from 3360 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Let's proceed to step 11:
The number 406 fits into 1120 2 times, leaving a remainder of 308.
Write down 2 as next digit of the result. 
Result so far: 190823.982
If we take 812 away from 1120, we end up with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Going ahead to step 12:
3080 divided by 406 is 7 with a remainder of 238.
The number 7 becomes the next digit in our result. 
Result so far: 190823.9827
Deduct 2842 from 3080 and we're left with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

On to step 13:
406 can be fit into 2380 5 times, resulting in a remainder of 350.
The number 5 becomes the next digit in our result. 
Result so far: 190823.98275
The remainder is 350 after subtracting 2030 from 2380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Let's proceed to step 14:
406 can be fit into 3500 8 times, resulting in a remainder of 252.
Write down 8 as next digit of the result. 
Result so far: 190823.982758
Deduct 3248 from 3500 and we're left with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Going ahead to step 15:
When dividing 2520 by 406, we get 6 with a remainder of 84.
The next digit of our result is 6. 
Result so far: 190823.9827586
Subtract 2436 from 2520 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 16:
The number 406 fits into 840 2 times, leaving a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 190823.98275862
The remainder is 28 after subtracting 812 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final result is 190823.98275862 with a remainder of 2.8e-08.
