70783991 ÷ 142 
We want to divide 70783991 by 142.

Let's proceed to step 1:
If we divide 7 by 142, we get 0 and 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.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 142

Going ahead to step 2:
70 divided by 142 is 0 with a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 70, we end up with 70.
Bring next digit (7) of the dividend behind the 70 and repeat the process: 707 / 142

Advancing to step 3:
When dividing 707 by 142, we get 4 with a remainder of 139.
The next digit of our result is 4. 
Result so far: 4.0
If we take 568 away from 707, we end up with 139.
Append the next digit (8) from the dividend to 139 and continue with: 1398 / 142

On to step 4:
If we divide 1398 by 142, we get 9 and a remainder of 120.
The next digit of our result is 9. 
Result so far: 49.0
Subtract 1278 from 1398 to get 120.
Bring next digit (3) of the dividend behind the 120 and repeat the process: 1203 / 142

Going ahead to step 5:
If we divide 1203 by 142, we get 8 and a remainder of 67.
Use 8 as the next digit of our solution. 
Result so far: 498.0
Subtract 1136 from 1203 to get 67.
Grab the next digit (9) from the dividend, add it to 67, then carry on: 679 / 142

Going ahead to step 6:
142 goes into 679 4 times with a remainder of 111.
The number 4 becomes the next digit in our result. 
Result so far: 4984.0
The remainder is 111 after subtracting 568 from 679.
Fetch the next digit (9) from the dividend, attach it to 111 and continue: 1119 / 142

On to step 7:
If we divide 1119 by 142, we get 7 and a remainder of 125.
Record the quotient 7 as the next digit in the result. 
Result so far: 49847.0
Deduct 994 from 1119 and we're left with 125.
Bring next digit (1) of the dividend behind the 125 and repeat the process: 1251 / 142

On to step 8:
1251 divided by 142 is 8 with a remainder of 115.
Use 8 as the next digit of our solution. 
Result so far: 498478.0
Subtract 1136 from 1251 to get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Step 9:
142 goes into 1150 8 times with a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 498478.8
The remainder is 14 after subtracting 1136 from 1150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 10:
142 can be fit into 140 0 times, resulting in a remainder of 140.
The next digit of our result is 0. 
Result so far: 498478.8
Subtract 0 from 140 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 11:
If we divide 1400 by 142, we get 9 and a remainder of 122.
Use 9 as the next digit of our solution. 
Result so far: 498478.809
Deduct 1278 from 1400 and we're left with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Moving on to step 12:
142 can be fit into 1220 8 times, resulting in a remainder of 84.
Write down 8 as next digit of the result. 
Result so far: 498478.8098
Subtract 1136 from 1220 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.

Let's proceed to step 13:
If we divide 840 by 142, we get 5 and a remainder of 130.
The number 5 becomes the next digit in our result. 
Result so far: 498478.80985
The remainder is 130 after subtracting 710 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 14:
142 can be fit into 1300 9 times, resulting in a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 498478.809859
If we take 1278 away from 1300, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 15:
If we divide 220 by 142, we get 1 and a remainder of 78.
Use 1 as the next digit of our solution. 
Result so far: 498478.8098591
If we take 142 away from 220, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 16:
780 divided by 142 is 5 with a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 498478.80985915
If we take 710 away from 780, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final outcome is 498478.80985915, with a leftover of 7e-08.
