Let's divide 58107711 by 840
Let's see how many times 840 fits into 58107711.

On to step 1:
The number 840 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 840

Step 2:
If we divide 58 by 840, we get 0 and a remainder of 58.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 58 to get 58.
Bring next digit (1) of the dividend behind the 58 and repeat the process: 581 / 840

Advancing to step 3:
581 divided by 840 is 0 with a remainder of 581.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 581 to get 581.
Bring next digit (0) of the dividend behind the 581 and repeat the process: 5810 / 840

Going ahead to step 4:
840 goes into 5810 6 times with a remainder of 770.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 5040 from 5810 and we're left with 770.
Take the next digit (7) from the dividend and append it to 770, then repeat: 7707 / 840

Let's proceed to step 5:
840 goes into 7707 9 times with a remainder of 147.
Put 9 as the next digit of the answer. 
Result so far: 69.0
If we subtract 7560 from 7707, we get 147.
Bring next digit (7) of the dividend behind the 147 and repeat the process: 1477 / 840

On to step 6:
When dividing 1477 by 840, we get 1 with a remainder of 637.
Use 1 as the next digit of our solution. 
Result so far: 691.0
If we subtract 840 from 1477, we get 637.
Append the next digit (1) from the dividend to 637 and continue with: 6371 / 840

Advancing to step 7:
The number 840 fits into 6371 7 times, leaving a remainder of 491.
Write down 7 as next digit of the result. 
Result so far: 6917.0
Subtract 5880 from 6371 to get 491.
Bring next digit (1) of the dividend behind the 491 and repeat the process: 4911 / 840

Advancing to step 8:
4911 divided by 840 is 5 with a remainder of 711.
Record the quotient 5 as the next digit in the result. 
Result so far: 69175.0
The remainder is 711 after subtracting 4200 from 4911.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7110, and continue the process.

Step 9:
7110 divided by 840 is 8 with a remainder of 390.
The next digit of our result is 8. 
Result so far: 69175.8
Deduct 6720 from 7110 and we're left with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Let's proceed to step 10:
If we divide 3900 by 840, we get 4 and a remainder of 540.
Write down 4 as next digit of the result. 
Result so far: 69175.84
If we take 3360 away from 3900, we end up with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Advancing to step 11:
When dividing 5400 by 840, we get 6 with a remainder of 360.
Use 6 as the next digit of our solution. 
Result so far: 69175.846
The remainder is 360 after subtracting 5040 from 5400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Going ahead to step 12:
If we divide 3600 by 840, we get 4 and a remainder of 240.
Write down 4 as next digit of the result. 
Result so far: 69175.8464
Subtracting 3360 from 3600 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 13:
If we divide 2400 by 840, we get 2 and a remainder of 720.
Record the quotient 2 as the next digit in the result. 
Result so far: 69175.84642
Subtract 1680 from 2400 to get 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Going ahead to step 14:
When dividing 7200 by 840, we get 8 with a remainder of 480.
Use 8 as the next digit of our solution. 
Result so far: 69175.846428
The remainder is 480 after subtracting 6720 from 7200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Advancing to step 15:
4800 divided by 840 is 5 with a remainder of 600.
Put 5 as the next digit of the answer. 
Result so far: 69175.8464285
If we take 4200 away from 4800, we end up with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Step 16:
6000 divided by 840 is 7 with a remainder of 120.
Put 7 as the next digit of the answer. 
Result so far: 69175.84642857
Deduct 5880 from 6000 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

After the division, we end up with 69175.84642857 and a remainder of 1.2e-07.
